Cast iron frames
According to material, they can be divided into two types: ductile iron frames and gray iron frames: Ductile iron frames are rarely used, generally have smaller specifications and require higher precision. The accuracy of high profile iron, such as ground iron and ductile iron frames, is greater than grade. Gray iron frames are widely used. Gray iron has low cost, short production cycle, simple process and durability, which is one of the reasons why manufacturers and users prefer it.
