Production Method for FeCoNiCrMn Powder

Typical production methods for FeCoNiCrMn powder include:

• Gasverstuiving?- High pressure inert gas used to atomize molten alloy to produce fine spherical powder with good flow and packing density.
• Verstuiven van water?- High velocity water jet breaks up molten metal stream into fine irregular powder particles. Lower cost but higher oxygen pickup.
• Mechanische legering?- Kogelmolen van gemengde elementaire poeders gevolgd door sinteren en secundaire atomisering.

Gas atomization provides the best control over powder characteristics like particle size distribution, morphology, purity and microstructure.
