Tungsten Alloy High-Temperature Molding Part

Description

Tungsten alloy high temperature tooling is also called as tungsten alloy extrusion dies or 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. And it does not require heat treatment before use.

Advantages

1. Tungsten alloy high temperature tooling has longer service life than parts made from steel or satellite.
2. Tungsten alloy extrusion die has good resistance to thermal cycling preventing cracking or heat-checking.
3. It has great hot wear resistance to erosion and excellent resistance to soldering.
