4J36 Low Expansion Alloy Invar 36 Curie Temperature 230°C Nilo 36 China Origin Fast Delivery

Low Expansion Alloy 4J36 Strip Wire Bar Curie Temperature 230°C

4J36 is well known as Invar36 worldwide. It is a Low Expansion Alloy with Curie point of around 230°C.Invar alloy (Invar 36) is a low expansion alloy consisting of 36% Nickel, balance Iron. Invar Alloy exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required, such as in precision instruments like optoelectronic devices, optical and laser benches, electronics, and other kinds of scientific instruments.
