Application:

It is mainly used in industrial refrigerating treatment, so that the matrix of the metal structure to generate a uniform, fine and dispersed precipitation. The precipitation of carbide will improve the abrasion resistance, friction performance and increase hardness of metal. The carbide is the ideal alternative to liquid nitrogen.

For the copper sleeve and bearings contracting, it is widely used in precise mechanical assembly. Applied to large scale equipment(cars, large engineering machineries, aircraft component, Aerospace equipment parts, Military equipment parts etc.) lower temperature test.
