Where you can buy electrical steel depends on how much you need. For a few sheets, go to a lamination prototype shop or a catalogue supplier. From about 500 kg, an exporter with its own cutting line can supply cut sheet. From 3 to 5 tonnes, you can buy part of a coil or a full coil. Mills themselves sell by the coil.
“Where can I get a small amount of silicon steel?” is one of the most repeated questions on engineering forums. The usual story is the same: one supplier wants a very high price for a single sheet, another only quotes by the tonne, and most don’t answer at all. This guide explains why that happens and which door to knock on for each quantity.
We’re Wuxi Zhongxin Special Steel (ZHX Steel). We supply grain-oriented and non-oriented coil, slit strip and cut sheet, so we’ll also state our own typical minimums and what we can do when you need less than that. If you haven’t settled the grade yet, start with our guide on how to choose electrical steel.
Key Takeaways
- No single channel covers every quantity. Match the channel to the amount: sheets, hundreds of kilograms, or tonnes.
- Mills sell full coils. Service centers and exporters with cutting lines exist to break those coils into smaller lots.
- Our own terms: coil typically from about 5 tonnes, cut sheet from 500 kg, both with about 15 days lead time.
- Less than a full coil, for example 3 tonnes, is cut from a coil. If it isn’t in stock, allow a few more days.
- A sample typically costs USD 200 including freight and takes about a week. The USD 200 is refunded when a bulk order follows.
- Electrical steel isn’t made as bar or rod. A rod-shaped core is built from stacked strips.
Who Sells Electrical Steel, and How Small Will Each Go?
Six kinds of seller handle electrical steel, and each one has a natural lot size. It helps to know each one’s usual size before you ask.
| Channel | Smallest practical lot | What you receive | Best for |
|---|---|---|---|
| Steel mill | Full coils, usually many tonnes per grade | Master coil | Large, repeat production |
| Exporter or supplier with its own slitting and cutting | Part of a coil, or a few hundred kilograms of sheet | Coil, slit strip, cut sheet, with mill certificate | Pilot lots and small production |
| Service center or local distributor | Lower than a mill; varies by company and stock | Slit or sheared material from stock | Buyers near the stock, fast delivery |
| Lamination maker or prototype shop | A handful of finished parts | Laser-cut or stamped laminations | Prototypes that need parts, not sheet |
| Catalogue or online retailer | One sheet | Small sheets, often without full test data | One-off experiments |
| Salvage | One old motor or transformer | Used laminations | Hobby builds, proof of concept |
The middle rows matter most for small buyers. A steel service center buys from mills and holds stock. Industry descriptions list its typical work as slitting, shearing, blanking, cutting to length and levelling, and note that it has a lower minimum order quantity than a mill and shorter lead times because the stock is already there.
One thing to check on any quote is who actually made the steel. Our guide on how to source electrical steel from China explains the difference between a mill, an authorised supplier and a trading company.
Why Do Mills and Exporters Quote in Tonnes?
Because electrical steel is made and handled as coil, and a coil weighs tonnes. Three practical reasons sit behind every minimum.
- The coil is the unit. A mill rolls, anneals and coats a coil as one piece. Selling half of it leaves the mill with a remainder it then has to place.
- Cutting creates leftovers. When a supplier slits or shears part of a coil for you, the rest stays in its warehouse until another buyer wants that grade and thickness.
- Order costs are fixed. The test certificate, export packing, documents and inland transport cost about the same for 300 kg as for 5 tonnes.
Our own numbers follow from this. A coil order typically starts at about 5 tonnes, roughly one coil, with a lead time of about 15 days. If you need less, for example 3 tonnes, we cut it from a coil. If that grade isn’t in stock, allow a few more days. Cut sheet starts at 500 kg, also with a lead time of about 15 days.
For how grade, slitting and certificates change the schedule on larger orders, see lead times and MOQ for custom electrical steel.
Where Can You Buy a Few Sheets or Under 200 kg?
Below a few hundred kilograms you have five practical routes. Which one fits depends on whether you need sheet, finished parts, or only enough material for a test.
Buy laminations, not sheet. If the goal is a prototype stator or core, a lamination shop is usually the shortest route. Prototype and low-volume laminations are normally laser-cut or wire-cut without tooling, and the shop supplies the steel from its own stock. Fraunhofer IFAM, for example, describes laser cutting electrical sheet for single parts and small batches. We compare what laser cutting, stamping and wire EDM cost, and how each affects core loss, in our guide to prototype motor laminations.
Catalogue suppliers. Industrial catalogues sell single sheets. Forum users report that the price per kilogram is many times the bulk price. For one experiment that can still be the cheapest total.
Ask a coil supplier directly. Many will send a sample of a stocked grade, and some can cut a small lot when the grade is on the floor. Our sample typically costs USD 200 including freight. If you need more than a sample but less than our usual minimum, tell us the grade, size and amount, and we’ll do our best to meet it.
Other buyers’ surplus. People who bought a full lot sometimes sell the rest. One forum poster ended up with a few tonnes of M250-35A sheet and offered it on to other builders.
Local motor rewind and transformer repair shops. They may sell offcuts or used cores.
Whichever route you take, ask what grade it is. Material sold as “silicon steel” on consumer marketplaces is not always non-oriented silicon steel, and without a grade name and thickness you can’t compare test results.
How Do University Labs and R&D Teams Get Samples?
Ask for a paid sample of a stocked grade, and say that it is for evaluation. Researchers often report asking for “engineering samples under 200 kg” and getting silence. From the supplier’s side, an open-ended request for a small free lot of a special size is work with no order behind it.
A paid sample changes that. Our terms are typical of how exporters handle it:
- Cost: typically USD 200, freight included.
- Time: about one week.
- Refund: the USD 200 is refunded when a bulk order follows.
Three things make a sample request easy to accept.
- Ask for a standard grade and thickness that is likely to be in stock, not a custom one.
- State the size of sample you need for your test, for example Epstein strips or a few sheets for laser cutting.
- Say what happens next: the quantity and timing of the pilot or production order if the sample passes.
If your project needs several hundred kilograms for a test series, tell us the amount. Cut sheet normally starts at 500 kg, and for a research project we’ll look at what we can do from stock.
Why Do Small Inquiries Go Unanswered, and How Do You Write One That Gets a Reply?
Most ignored inquiries are missing the facts a supplier needs to quote. “Please send price for silicon steel, small quantity” can’t be answered, so it isn’t. A complete inquiry takes five minutes to write.
| Include | Example | Why it matters |
|---|---|---|
| Grade and standard | M270-35A (EN 10106), or 35W270 | Sets the price class |
| Thickness and width | 0.35 mm × 1,000 mm | Decides whether stock fits |
| Form | Cut sheet 1,000 × 2,000 mm | Coil, slit strip and sheet have different minimums |
| Quantity | 600 kg now, 5 tonnes per quarter later | Shows whether there is a follow-on order |
| Application | Servo motor stator, laser-cut | Lets the supplier suggest an equivalent grade |
| Destination and terms | Hamburg, CIF | Freight is a large share of a small order |
| Documents | EN 10204 3.1 certificate | Avoids a surprise at delivery |
A message built from that table looks like this:
We are a motor developer in Germany. We need 600 kg of M270-35A, 0.35 mm, as cut sheet 1,000 × 2,000 mm, for a pilot build of 40 laser-cut stators. If the pilot passes, we expect about 5 tonnes per quarter. Please quote CIF Hamburg with an EN 10204 3.1 certificate, and tell us the lead time. If this grade is not in stock, please offer the nearest equivalent.
Two more habits help. Give a grade in the supplier’s own naming system if you can; our grade equivalents guide maps GB, EN, JIS and ASTM names.
And say which certificate you need. Our guide to EN 10204 3.1 and 3.2 certificates shows why the two are not interchangeable.
Can Sheet Be Slit or Cut Smaller to Reduce Freight?
Yes. Any supplier with a slitting or cut-to-length line can deliver narrower strip or smaller sheets, and smaller pieces pack onto standard pallets. Full-size sheets of about 1.1 × 1.2 m are awkward and costly to move in small numbers.
Three points to settle before cutting.
- Cut to the size your process uses. If your laser bed takes 500 × 1,000 mm, order that. Every extra cut later is your scrap.
- Don’t fold or bend sheets to fit a box. Bending strains the steel, and strain raises core loss. Ship flat, or as a small coil.
- State the tolerance you need. Width tolerance and edge burr depend on the slitting setup. Our article on slitting tolerances and camber lists what to check.
Narrow slit coils are the most compact form. A few hundred kilograms of strip ships as one or two small coils on a pallet. Our electrical steel slitting service page describes the widths and forms available.
Is There Electrical Steel in Bar or Rod Form?
No. Electrical steel is only produced as thin sheet and strip, because its job depends on being thin. A laminated core is a stack of thin iron sheets, each coated with an insulating layer, and the thinner the sheets, the lower the eddy-current loss. A solid bar of the same alloy would lose that advantage completely, which is why solid iron cores aren’t used in transformers or inductors.
If your design calls for a rod-shaped core, there are four ways to get one.
| Need | Practical option |
|---|---|
| AC core in a rod or bar shape | Stack narrow slit strips or cut laminations into a bar and clamp or bond them |
| DC electromagnet or pole piece | Solid soft iron or low-carbon steel bar is acceptable, since there is no alternating flux |
| High frequency | Ferrite rod or a powder core |
| Round cross-section, AC | Stack strips of stepped widths to approximate a circle |
For the first option, order slit strip at the bar width you need. A stack of 0.35 mm strips 20 mm high holds about 55 layers.
Can You Reuse Laminations from Old Transformers and Motors?
Yes, for a prototype or a hobby build. It is a common piece of forum advice, and it works within limits.
| Check | Why |
|---|---|
| You won’t know the grade | Old laminations carry no certificate, so loss and permeability are guesses |
| Coating may be damaged | Prying a varnished or welded stack apart scratches the insulation between sheets |
| Bent sheets lose performance | Strain from disassembly raises core loss |
| Shape is fixed | You can re-cut smaller parts from large transformer sheets, but not larger ones |
| Transformer sheet is usually grain-oriented | Its low loss applies in one direction only, which suits few motor designs |
So reused laminations are fine for proving a concept. They are a poor basis for an efficiency measurement or for anything you plan to sell. The same caution applies to cheap lots sold as new: our guide to prime vs secondary CRGO explains how reclaimed and downgraded material reaches the market.
What We Supply, and from What Quantity
These are our normal terms as of October 2026. They are typical figures, and we confirm the exact quantity and date with each quotation.
| You need | What we do | Typical minimum | Typical time |
|---|---|---|---|
| Material to test | Sample of a stocked grade | USD 200 including freight, refunded against a bulk order | About one week |
| Cut sheet | Sheared to your size | 500 kg | About 15 days |
| Less than a full coil | Cut from a coil, as coil or slit strip | For example 3 tonnes | About 15 days if in stock; a few more days if not |
| Full coil | Coil as produced, or slit to width | About 5 tonnes | About 15 days |
These are starting points, not limits. If your quantity falls below them, send it anyway: we try to meet each customer’s requirement as far as stock and cutting allow. For a real example of a slit strip order and how it was packed, see our 50A310 slit strip order profile.
To get a quote, send the seven items from the inquiry table. Request a quote and we’ll reply with price, lead time and the certificate type.
Bottom Line
Match the channel to the quantity.
- A few sheets or parts: prototype lamination shop, catalogue supplier, salvage, or ask a coil supplier what it can cut from stock.
- Material to test: a paid sample from a coil supplier. Ours is typically USD 200 with freight, refunded on a bulk order.
- About 500 kg and up: cut sheet from a supplier with a cutting line.
- About 3 tonnes: part of a coil, cut from stock.
- About 5 tonnes and up: full coils.
And whatever the quantity, write the inquiry with grade, size, form, quantity and destination. A complete inquiry is the main reason a small buyer gets an answer.
FAQ
What is the minimum order quantity for electrical steel?
It depends on the form and the seller. Mills sell full coils. From us, coil typically starts at about 5 tonnes, a smaller lot such as 3 tonnes can be cut from a coil, and cut sheet starts at 500 kg. For less than that, ask: we do our best to meet smaller requests, starting with a sample.
Can I buy just one sheet of electrical steel?
Yes, from a catalogue or online supplier, or as an offcut from a lamination shop. Expect a much higher price per kilogram than bulk material and limited test data. If you need parts, ordering finished laser-cut laminations is usually simpler than buying a sheet.
How much does an electrical steel sample cost?
Our sample typically costs USD 200 including freight and takes about a week. The USD 200 is refunded when a bulk order follows. Other suppliers set their own terms, so ask what the sample contains and whether freight is included. Our guide to Incoterms for electrical steel explains freight terms on the order that follows.
Why won’t suppliers reply to my inquiry?
Usually because the inquiry can’t be quoted. A message with no grade, thickness, form or quantity gives the supplier nothing to price. State those four items, add the destination and the follow-on volume, and the supplier has what it needs to answer.
Is electrical steel available as rod or bar?
No. It is made only as thin sheet and strip, because thin insulated layers are what keep eddy-current loss low. For a bar-shaped AC core, stack slit strips. For a DC electromagnet, a solid soft iron bar is acceptable.
Can I use laminations from an old microwave oven transformer?
For a hobby project or a proof of concept, yes. You won’t know the grade, the coating may be damaged when the stack is separated, and the sheet is fixed in shape. Don’t use salvaged laminations to measure efficiency or in a product.
