    for the aerospace industry

Description

VDM® Powder 780 is the powder variant of an age-hardenable nickel-cobalt-chromium alloy for use in additive manufacturing. Hardenability is achieved by means of admixtures of niobium, titanium and aluminum.
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

Microstructural properties

VDM® Powder 780 has an austenitic microstructure where different phases can occur. By means of different heat treatments, 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.

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 spacecraft, motor vehicle turbo chargers, high-strength screws, springs and mounting elements, and for heat-resistant tools in
forgeries, extruders and separating shearers.
