Recommended industry choices for powder metallurgy natural graphite models
Particle size | Application Scene | Advantage | Limitation |
Coarse（+100mesh~+200mesh） | Conventional structural components (such as gears, bearings) | Improve suppressed liquidity and reduce costs | Poor mixing uniformity |
Medium（-100mesh ~-325mesh） | High density components (such as oil containing bearings) | Improve sintering density and reduce porosity | Possible increase in suppression resistance |
Ultra-fine（-325mesh~Submicro） | Precision electronic contacts, MIM feeding | Enhance conductivity/lubrication uniformity | Easy to agglomerate, requiring surface treatment |
