Precision Alloys

Precision alloys are metal materials with special physical properties (such as magnetic , electrical , and thermal properties) . The vast majority of precision alloys are based on ferrous metals , and only a few are based on non-ferrous metals . Usually include magnetic alloys (see magnetic materials ), elastic alloys , expansion alloys , thermal bimetals , electrical alloys , hydrogen storage alloys (see hydrogen storage materials ), shape memory alloys , magnetostrictive alloys (see magnetostrictive materials ),etc. 

Precision alloys are divided into 7 categories according to their different physical properties, namely: soft magnetic alloys , deformed permanent magnetic alloys , elastic alloys, expansion alloys, thermal bimetals, resistance alloys , and thermoelectric alloys.

Soft magnetic alloys：Permalloy 80(Mumetal); 1J79(Alloy 79); 1J85(Alloy 85); Hiperco 50A

Elastic alloys：3J58,3J53, 3J01 Eect

Expansion alloys: Kovar Alloy(4J29), Invar 36(4J36), Super Invar (4J32),Alloy 42(4J42), Alloy 50(4J50) Ect
