The lubrication performance of metal silicon depends on the size of the metal silicon scale. The larger the scale, the smaller the friction coefficient, and the better the lubrication performance; Chemical stability, metal silicon has good chemical stability at room temperature, resistant to acid, alkali, and corrosion; Good plasticity, good toughness of metal silicon, and can be ground into thin sheets; Heat resistant vibration, metal silicon can withstand drastic temperature changes without damage when used at room temperature; When the temperature suddenly changes, the volume of metal silicon does not change much and will not produce cracks.
