Wax Additives for PM Lubrication and Surface Quality

Powder metallurgy (PM) is widely used to produce precision metal parts. Proper lubrication during compaction and sintering is essential to reduce die wear and achieve high-quality surfaces. Wax additives are key to enhancing these properties.

Advantages of Wax Additives in PM

1. Superior Lubrication: Reduces die friction, preventing part defects and tool wear.

2. Surface Quality Enhancement: Produces smooth, defect-free sintered surfaces.

3. Residue-Free Burnout: Fully decomposable waxes prevent carbon deposits.

Technical Considerations

Micronized polyethylene and paraffin waxes are widely applied for their excellent lubrication and clean burnout properties. The exact addition rate should be determined based on part geometry, powder type, and compaction pressure.

A PM automotive parts manufacturer integrated a high-performance micronized wax into their powder blend and observed reduced die wear and cleaner sintered surfaces.
