    Description

    Features:
    Material:Graphite
    High temperature resistance: the melting point of graphite is 3850, the boiling point is 4250 65 The strength of graphite strengthened with the increase of temperature, and the strength of graphite increased by 2000 times.
    Electrical conductivity and thermal conductivity: graphite has one hundred times higher conductivity than ordinary nonmetallic minerals. Thermal conductivity exceeds steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature, and even at extremely high temperatures, graphite becomes an adiabatic body. Graphite conducts electricity because each carbon atom in the graphite forms only three covalent bonds with other carbon atoms, and each carbon atom retains one free electron to transfer charge.
    Lubrication: The lubrication performance of graphite depends on the size of graphite flake, the larger the flake, the smaller the friction coefficient, the better the lubrication performance.
    Chemical stability: Graphite has good chemical stability at room temperature, can resist acid, alkali and organic solvent corrosion.
    Thermal shock resistance: graphite can withstand drastic changes in temperature when used at room temperature without damage, temperature mutation, the volume of graphite changes little, will not produce cracks.
