Mi-Tech Metals Diemitechâ„¢ Tungsten-Based Metal
Categories: Metal; Nonferrous Metal; Refractory Metal; Tungsten Alloy

Material Notes: Diemitech is a new tungsten-based material used for high temperature tooling, die casting, extrusion dies, hot upsetting, and electro brazing. It has a higher tungsten content than similar available materials, giving it superior refractory properties resulting in greater resistance to erosion and wear. Diemitech maintains good thermal conductivity and physical properties at high working temperatures.

Advantages of using Diemitech:Tools run much cooler because its thermal conductivity is 3-4 times that of steel.
Low thermal expansion - 1/3 that of steel.
Withstands thermal shock.
Excellent mechanical properties at elevated temperatures.
Resists erosion and scaling.
Minimizes soldering and heat checking.
No costly treatment required, normally can be placed into service as machines.
Superior physical properties compared to steel at high working temperatures.
Diemitech is machinable, similar to cast iron.
