Natural Graphite Powder is a critical additive in powder metallurgy (PM), enhancing lubricity, electrical conductivity, and sintering performance in metal-based composites. XINGSHI supplies high-purity graphite tailored for iron-based, copper-based, and specialty alloy PM parts.
✅ Key Benefits:
✔ Improved Compaction – Reduces friction during pressing
✔ Enhanced Sintering – Promotes densification & reduces porosity
✔ Cost-Effective – Optimizes production efficiency
| Parameter | Standard Grade | High-Purity Grade | Ultra-Fine Grade |

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 |
