Product Description
Our NiCr resistance heating wire combines nickel and chromium for outstanding performance as a resistance heating element. Cr20Ni80 offers higher nickel content for maximum oxidation resistance and stability up to 1200°C, while Cr15Ni60 provides cost-effective high resistivity for many industrial uses. Both grades feature non-magnetic properties, excellent formability into coils or spirals, and long service life in continuous high-heat operations.
