Depending on the use conditions, stricter analysis limits apply to certain alloy elements. VDM® Powder 780 contains low amounts of oxygen of up to 0.03%.
Features & Benefits
- Labeling Claims
- Base Chemicals Features
- Features
VDM® Powder 780 is characterized by:
- Spherical particles
- High purity
- Low oxygen content
- Good weldability
- Higher application temperature (potentially up to 750°C)
- High temperature oxidation resistance
- Corrosion Resistance
As a result of the high chromium and cobalt content, conventionally manufactured VDM® Alloy 780 has a good high temperature oxidation resistance.

- Applications
VDM® Powder 780 can be used for many demanding applications. Originally, it was developed for static and rotating components in aircraft turbines such as housings, mounting elements and turbine disks.
The material can also be used for static and rotating components in stationary gas turbines, rocket drives and space-craft, motor vehicle turbo chargers, high-strength screws, springs and mounting elements, and for heat-resistant tools in forgeries, extruders and separating shearers.
Properties

- Physical Properties
- Microstructural Properties
VDM® Powder 780 has an austenitic microstructure where different phases can occur. By means of different heat treat-ments, graduated mechanical properties of the material can be achieved. The excellent mechanical properties of VDM® Powder 780 result from the γ’-formation during precipitation hardening.
