Tungsten alloy in high temperature tooling is called as tungsten alloy extrusion dies and die casting components.
　　Tungsten alloy can save time and money in hot metal working. The high tungsten content offers good resistance to thermal cracking, erosion, soldering and the effects of heat cycling in hot metal working processes. Experience has shown that, due to its non-wetting properties, tungsten alloy has significantly increased longevity over the equivalent parts in steel or cast iron. Tungsten alloy does not require heat treatment before use.
　　Tungsten alloy can save time and money in the extrusion of copper and copper alloys because its high tungsten content offers good resistance to metal pick up, erosion, soldering and the effects of heat cycling such as thermal cracking. This significantly increases the operating life of die inserts compared to the same components made from steel or stellite.
