Flake graphite is a natural solid lubricant with a layered structure. It has complete crystallization, thin flakes, good toughness, and excellent physical and chemical properties such as good temperature resistance, self-lubrication, conductivity, thermal shock resistance, and corrosion resistance.
Natural flake graphite has good temperature resistance and can remain stable in high temperature environment. Its layered structure makes the graphite have excellent self-lubricity and can be used as a solid lubricant.
High purity graphite refers to graphite material that has been refined to remove impurities, achieving a carbon content of 99.9% or higher. It possesses excellent mechanical strength. And density and purity are both high, making it an ideal material for various applications.
Micro-powder graphite is a fine, high-purity graphite material often processed to meet specific particle size requirements. It is widely used in various industries due to its excellent properties, such as high-temperature resistance, lubricity, conductivity, and chemical stability.
