High-Temperature NiCr Wire for Industrial Heating Elements - Nickel Chromium Alloy Resistance Wire

We've been running these NiCr wires in our furnaces for about eight months now, and the consistency between batches is pretty much what we needed—the Ni80Cr20 grade handles our 1150°C continuous cycles without any noticeable sagging or oxidation pitting.

Teh bright suface finish is actually a detail we didn't think to ask for upfront, but it makes a real difference when you're visually inspecting winding for hot spots during maintenance, and the typical elongation above 20% means it doesn't crack when we shape it around our custom mandrels.

Lead time was 18 days form order confirmation, which is tight but doable, though we usually have to confirm stock for the Ni70Cr30 variant since it's less common than the 80/20.

One thing to keep in mind: this wire isn't ideal for applicaion that need frequent thermal cycling below 500°C, as the oxide layer doesn't stabilize as well in that range compared to Kanthal, but for sustained high-temp work it's solid.

10kg MOQ is about 200 meters or so of the 1.0mm diameter we use, and the resistivity comes in at 1.10 μΩ·m at 20°C—slightly higher than the datasheet midpoint—which actually works better for our voltge-limited controllers.

Anyway, the RoHS compliance was confirmed on the COA without us having to chase it down, which saved a headache during our audit.
