Cr20Ni30 and Cr20Ni35 is an austenitic nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1150°C. Cr20Ni30 and Cr20Ni35 is especially characterized by high resistivity and relatively low prices when compared with other nickel-chromium alloys. In spite of its relatively high iron content, NiCr3020 is resistant to oxidation and chemical corrosion. Cr20Ni30 and Cr20Ni35 is weak-magnetic.
