Invar Alloy/ Invar sheet/ Invar36 sheet
we are specialized in producing Invar alloy, also known as the expansion of low-alloy 4J36, Invar, Invar 36, Nilo36, FeNi36, K96300, ASTM-F1684, and so on.
The implementation of standards: YB / T 5241-93
Use: -60 ° C - 80 ° C air temperature change, there are more the lower expansion coefficient of plastic and good for making changes in the temperature range of near-constant size of the components are widely used in radio, precision instruments, equipment and other industries, so measuring standards, the microwave cavity, the two-metal layer, such as fluctuations in.it can be made in line with its customer's specifications wire, bar, pipe, strip.
