Tungsten copper hot hydrostatic extrusion is a kind of new manufacturing process based on powder metallurgy technology. Tungsten copper material is composed of tungsten and copper, which contains all advantages of these two metals, which can be widely used in high-voltage switch, vacuum switch, electrical contacts, EDM electrodes, welding electrode and plasma plating electrodes fields.


【Know Tungsten】Tungsten Copper CIP

tungsten copper CIP picture

Cold Isostatic Pressing, CIP, it refers to the isostatic pressing technique carried out at the room temperature. CIP usually uses rubber and plastics as mold wrapped materials, the liquid as the medium, the pressure is 100-630MPa, which mainly applied in powder molding. The purpose is to provide a sintered preform for the next process, such as forging or HIP process and so on. Compared with common molding process, tungsten copper CIP process has more uniform compacts and higher efficiency.
