NiCr 30/20 (1.4860) has high resistivity and relatively low prices when compared with other nickel-chromium alloys, can be used at operating temperature up to 1000°C. Although it has relatively high iron content, NiCr 30/20 is resistant to oxidation and chemical corrosion.
Common trade names: NiCr30/20, Ni30Cr20.
