4J32 alloy is also called Super-Invar alloy.In -6o℃ to 8o℃ temperature range the expansion coefficient is lower than that of 4J36, but the low temperature structure stability is not good as that of 4J36. It is primarily used for manufacture high precision instrument parts that require high-accuarcy dimensions within the range of ambient temperature variations.
