Good Price With High Quality 4J36 Plate Manufacture Invar 36 Price Per Kg
1 . Description:
4J36 is a special low-expansion iron-nickel alloy with ultra-low expansion coefficient. The control of carbon and manganese is very important. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment can stabilize the thermal expansion coefficient within a certain temperature range.
