This type of dies made of ceramet is mainly used for hot extrusion of copper and its alloys, including Ti, stainless steel and Al alloys.

The average serving life of these dies is in the range of 500 to 5000 work pieces a die, and is 10 to 100 times more than that of traditional steel dies. The production expense in dies is reduced by above 60%. The precision and surface qualities of the extruded products are better, and the production efficiency and finished products rate are increased. Most of the Copper processing factories have used this patented dies in China.

Property: High thermo stability and abrasive resistance; No oxidizing in high temperature; No deformation, no hanging up; High precision of finished products; High surface quality; High finished product rate
