4J32 4J36 4J29 Super Invar
4 j32 is also called Super Invar alloy (Super Invar alloy. In 60 ~ 80 ℃ temperature range, its expansion coefficient is lower than 4 j36 alloy, but the organization is 4 j36 alloy poor stability at low temperature. This alloy is mainly used in the manufacture of requirements in the environmental temperature change range size high precision instrument parts
Note:
Super Invar is also known as 32HK(Russia),Super-Invar,Super Nilvar, SI(Japan),Invar Superieur,Chinese 4J32,etc.
Usage:Super invar are suitable for environmental temperature,make dimensional precision parts for instrumentation.
Specification:Sheet/Plate,Bar/Rod, Wire/Coil,Tube/Pipe/Capillary
