Material Characteristics

Waspaloy is a hardenable nickel-base superalloy with very good strength properties at temperatures of up to approx. 980 °C. Due to its good oxidation resistance, the material is frequently used in gas turbines. Additive manufacturing enables a wide range of applications across multiple industries through functional integration at high temperatures.

  1. The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
