We work off stock for most outer diameters in that 2mm to 4mm range, but the 6mm or custom builds usually need about 20 days or so—plan accordingly if you're buying for a tight timeline.
It basically tops out at around 40 watts per meter and 600 volts, which covers most automotive and medical heating loops we see, but it's not built for high-frequency signal or power transmission, so don't use it for that.
The hot deformation test comes in under 30%, and the insulation resistance sits at least 5 MΩ, which is solid for environments that see up to 200°C continuous or even 250°C spikes—some buyers push the upper limit on the nichrome or CuNi core though (usually for higher ohm/m values like 40).
Anyway, teh DC resistance tolerance is tight at ±5%, and the outer diameter is +0.2/-0.1mm, so if you're sketching a loom or a heater mat layout, assume bulk will land inside that window.
5, our company offer a flat and round profile here, and what it does is use a glass fiber core skeleton wrapped in the alloy wire, then silicone sheath—one detail that's easy to miss is the sparks test comes back with no spark-over, which matters in a medical setting.
You will get a COA with each reel, and our company can do custom resistnce values form 0.3 ohm/m to 10,000 ohm/m, just confirm the lead time for anything outside the standdard 0.3, 1.4, 3, or 5 ohm/m options.
Yes, this cable is certified ISO9001, CCC, and RoHS. We can include copies of the certificates with your shipment — just let your sales rep know.
That range is standard, but we can customize the conductor size for larger volumes. Contact us with your specific needs and we'll work out the MOQ.
You can pick either nichrome or CuNi wire for the heating coil — it depends on your target resistance and temperature requirements. Both options are available on order.
For a standard spec order like 1000 meters, lead time is usually 15-20 working days. Custom specs or larger quantities may add a few more days.
Store it in a cool, dry place away from direct sunlight, ideally between 5°C and 35°C. Keep it in its original packaging to avoid dust or moisture exposure.
