Powder metallurgy (PM) is a manufacturing process that uses metal powders—including graphite—to produce solid components through compaction and sintering. This method is widely used in the automotive, aerospace, medical, and tooling industries for its efficiency, minimal material waste, and high precision.
In PM, graphite plays both a functional and technical role, acting as a lubricant, sintering aid, and property modifier.
Internal Lubricant
Reduces friction during compaction
Enhances mold filling
Minimizes die wear
Sintering Aid
Promotes diffusion bonding between metal particles
Improves consistency of sintered structures
Property Enhancer
Boosts thermal and electrical conductivity
Adds self-lubricating properties to final components
Suitable for standard PM applications
Purity: 85–99.9%
Common sizes: -200 mesh, -325 mesh
Cost-effective with good lubricity
Used in friction components
High purity and uniform particle size
Ideal for high-spec technical parts
