Alloy 42
Alloy 42,ASTM F30,UNS k94100,(Fe-42Ni) ,Chinese 4J42 42 Alloy, a low expansion alloy, is very similar to Invar 36 with a slightly different Coefficient of Thermal Expansion. This nickel-iron alloy is ideal forlid, lead frames, stencil/etching, telecommunications and aircraft industry, offering a more affordable alternative to Kovar when a tight seal is not required.
