The melting point of nickel is high. Nickel-based alloy powders often work well at temperatures up to 1200°C.
The structure of the alloy provides good resistance to oxidation. In high-temperature environments, the alloy forms a thin, protective oxide layer, which prevents further damage from oxidizing agents.
When used in compositions where materials face cycles of stress, the nickel-based alloy powder helps parts absorb vibration and shock. It makes components suitable for work under repetitive loads.
It has a good mix of strength, ductility, and hardness.
Another important property is its ability to form a good bond during sintering.
