Powder metallurgy (PM) has become a cornerstone of modern manufacturing, especially in the automotive, aerospace, and machinery industries. Its ability to produce complex shapes with minimal material waste makes it highly cost-efficient. Yet, the performance of sintered components relies heavily on the composition and preparation of the powders. Among the critical additives, natural flake graphite plays a central role as both a carbon source and a lubricant during compaction and sintering.

Discover how natural graphite powder enhances masterbatch formulations by imparting conductivity, thermal stability, and antistatic properties to plastics and polymers.

In grease applications, natural flake graphite acts as a solid film lubricant, maintaining lubrication even under boundary or dry-running conditions. This is especially valuable in situations where oil separation or evaporation can lead to metal-to-metal contact.

Efficient thermal management is crucial to the performance and lifespan of today’s high-power electronics, EV batteries, and aerospace components. Natural graphite—thanks to its high in-plane thermal conductivity and light weight—has become a material of choice for engineers seeking efficient passive cooling.

Discover how natural graphite is critical for high-performance lithium-ion batteries and EVs, with global demand surging 200% since 2019. Explore graphite’s benefits, market trends, and how to choose the right grade.

In May 2025, China’s flake graphite exports fell for the second consecutive month, while new projects in Australia and rising U.S. tariffs on Chinese graphite are reshaping the global supply landscape.
