Special alloy formulations, non-standard diameters, private labelling and…
Custom capabilities
- Custom alloy formulations — non-standard NiCr/NiSi ratios, special element additions
- Non-standard diameters — φ0.015 mm to φ8.0 mm, custom tolerance classes
- Special surface finishes — electro-polished, nickel-plated, tin-coated
- Custom spool sizes — DIN 80 / 125 / 160 / 250 / 400, plywood reels, custom labelling
- Private labelling — your part number, your branding on the spool
- Contract drawing — we draw your wire to your specification under NDA
- Dual certification — IEC 60584-1 + ASTM E230 on the same batch at no extra charge
- Pre-cut lengths — spooled to your exact metre requirement
- Sample melts — 5–50 kg trial batches for alloy development
How it works
- Specification — send us your target alloy composition, EMF curve, diameter, tolerance and quantity. Our metallurgist reviews and confirms feasibility, typically within one business day.
- Sample melt — for new alloy formulations we produce a trial melt first. You test the wire in your application, and we iterate composition until the EMF output matches your specification.
- Production — once the sample is approved we move to full production. Every batch carries the same furnace-number traceability and test certification as our standard products.
Frequently Asked Questions
What is the minimum quantity for a custom alloy?
50 kg for a production custom melt. Trial batches of 5–50 kg are available for alloy development, so the formulation can be proven before it is scaled.
Can you draw a non-standard diameter?
Yes — φ0.015 mm to φ8.0 mm, with custom tolerance classes, special surface finishes (electro-polished, nickel-plated, tin-coated) and spool sizes from DIN 80 to DIN 400.
How does a custom order proceed?
Three stages: specification review with a metallurgist within one business day, then a 5–50 kg sample melt iterated until the EMF output matches your target, then full production carrying the same furnace-number traceability as standard products.
Do you offer private labelling and contract drawing under NDA?
Yes. Spools can carry your part number and branding, and we draw wire to your specification under NDA.
Bottom line: Custom work runs on the same traceability as standard products: a 5–50 kg sample melt is iterated against your target EMF curve before any production commitment, then full batches carry the same furnace number, test certification and dual IEC/ASTM certification as the catalogue range.
