Nickel-Chromium AlloysNickel-Chromium Alloys are characterized by high resistivity, good oxidation resistance and very good form stability. They have good ductility after using and excellent weldability.NiCr alloys are used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.Main grades and propertiesNi30Cr20Chemical composition %Ni30.0~34.0Cr18.0~21.0FeBalanceHighest service temperature ℃1100Melting point ℃1390Density g/cm37.90Resistivity μΩ.m,20℃1.04Elongation %≥20Specific heat J/g.℃0.500Thermal conductivity KJ/m.h.℃43.8Coefficient of linear extensibility α×10-6/℃19.0MicrostructureAusteniteMagnetic propertynonmagnetic
