Improving Lubrication and Flow in Powder Metallurgy with Micronized Waxes

In powder metallurgy, micronized wax additives act as internal lubricants to improve powder compaction, ejection, and sintered surface quality without residue or interference.

Functional Advantages

• Die Wall Lubrication: Reduces ejection force during pressing.

• Flow Aid: Improves fill consistency in complex dies.

• Clean Burnout: Leaves minimal residue during sintering.

Wax Selection Criteria

• Melting point: 105–130°C

• Ash content: <0.05% for clean combustion

• Particle size: <10 µm for homogeneous blending

Typical Use Cases

Measurable Impact

• Green density increased by up to 5%.

• Sintered part surface roughness reduced.

• Press force reduced by 10–20%.

Micronized wax additives for powder metallurgy increase productivity and part quality while reducing tool wear and contamination risks.
