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—most 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
