Tungsten Alooy High-Temperature Tooling
High-Temperature Tooling
If your work involves die casting, extrusion or other high-temperature tooling applications, you know the challenges of working in an extreme environment. It¡¯s hard to keep everything up and running¡ªmost materials just can¡¯t cut it. Now Chinatungstens¡¯ high-density alloys can stand the heat.
Chinatungsten¡¯s tungsten alloys can withstand just about anything you can dish out. With high-thermal conductivity (three to four times that of steel), and low-thermal expansion (one-third that of steel), it¡¯s an excellent choice for high-heat applications. Diemitech:
resists erosion, scaling, chipping and breakage
minimizes soldering and heat checking is machinable, similar to gray cast iron
withstands thermal shock
doesn¡¯t require costly heat treatment (tools can be placed into service as machined)
maintains superior physical properties at high temperatures
