AMPERSINT® high-alloyed metal powder solutions for Hot Isostatic Pressing (HIP)

Hot Isostatic Pressing is used to densify powders or cast and sintered parts at high pressure and at temperatures from 900 °C to 1,250 °C for example for steels and superalloys. The Hot Isostatic Pressing process provides improved stability and mechanical properties of solid parts due to the fine and homogeneous isotropic microstructure. Furthermore Hot Isostatic Pressing permits the use of composite materials and the creation of large and complex shaped components from powders.

Construction Part Hot Isostatic Pressing
It is very complementary to other powder metallurgy processes such as Metal Injection Molding (MIM), pressing and sintering, or Additive Manufacturing technologies. The application areas are broad, ranging from offshore applications to aviation, tooling and electronics.

In close collaboration with our customers we produce high-alloyed AMPERSINT® metal powders of all major standard compositions, such as nickel- (Ni), cobalt- (Co) and iron- (Fe) based alloys, as well as customized solutions with tailored chemistries and particle size distributions. Available from small to large scale batch sizes.
