High Temp 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. Fortunately, Mi-Tech Metals' high-density alloys can stand the heat.
Machining High Temperature Tooling
Our tungsten alloys (particularly our 93W-Ni-Fe-Mo product) 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
