The material are almost made from Ni-Cr alloy with benefits of increased products life, light weight, reduced distortion, stable quality and smooth surface of the castings. To make sure the longer service life and guarantee the physical properties of the castings, the 100% new raw material like pure nickel plate, FeCr chrome alloy are normally use.
