You're looking at roughly 0.1mm to 8.0mm diameter range for bare solid wire, and we've got oxidized wire from 1.2mm up to 8.0mm — that's teh sweet spot for most industiral ovens or furnace work, and we usually have stock in the 0.5mm to 3.2mm sizes for quick dispatch to US or EU buyers.
It's basically Chromel and Alumel alloys, Ni90Cr10 for the positive leg and NiAlCo or NiSi3 for the negative, so you're getting the standard Type K pairing that handles continuous temps up to 1,100°C, and we can customize the gauge if your applicaion needs something tighter than the usual 0.5mm or 1.0mm.
Compliance isn't an issue since we meet IEC 584-1/2/3, ANSI MC 96.1, ASTM E230, and DIN EN 60584-1/2, so you won't have trouble with import docs for the UK or EU — RoHS and ISO9001 certs come with every batch, and our company can provide COAs on request (usually within 2-3 days of order).
One thing that catches some buyers off guard is that this wire isn't suited for direct immersion in molten metals or corrosive acidic environments without proper sheathing — it's a bare thermocouple wire for standard temp sensing, not a probe assembly, so plan your instalation accordingly.
4 to 6 weeks lead time for custom diameters outside our standard range, but we ship on DIN spools or in coils and cartons depending on your quantiy — most buyers go with the 1.0mm or 1.6mm for general use, and the oxidized option (1.2mm to 8.0mm) handles oxidation better in high-temp air furnaces.
For custom orders, we typically require an MOQ of 500 meters for smaller diameters like 0.1mm. If you need less, we can check if we have standard stock available.
Custom orders for oxidized wire usually take 10-15 working days after order confirmation, since we produce it specifically for you. Standard sizes might ship faster.
Yes, we include the ISO9001 certificate and a material test report with every shipment. We can also provide RoHS compliance docs upon request.
We stick to the standard Ni90Cr10 for Chromel and NiAlCo/NiSi3 for Alumel to meet IEC and ASTM specs. Custom alloy ratios aren't available, but we can adjust diameter and packaging.
Just keep it in a dry area at room temperature, away from corrosive chemicals. The DIN spools or cartons we use protect it fine for storage up to a year.
