Product Description and Application
Alloy32 is also also known as 4J32, Super Invar
Alloy32 alloy is called Super-Invar alloy. Its expansion coefficient is lower than 4J36 alloy in the range of -60 ~ 80℃, but its microstructure stability is worse than 4J36 alloy at low temperature. The alloy is mainly used in the manufacture of highly precise instrument parts requiring sizes within the range of ambient temperature variations.
