Cr20Ni80 consists of approximately 80% nickel and 20% chromium. This composition gives the wire a unique balance of properties: outstanding electrical stability, excellent resistance to oxidation, and the ability to perform at temperatures up to 1250°C. With an electrical resistivity of about 1.09 μΩ·m at room temperature, it offers precise heating performance, making it ideal for designing heating elements of varying shapes and capacities.

Supplied on spools, our Cr20Ni80 Nichrome wire is easy to handle, transport, and integrate into custom heating systems. The spool format allows engineers and manufacturers to cut and wind the wire according to their exact design needs, whether that’s for large-scale industrial furnaces or compact electronic devices.
