浸锑石墨环

Antimony-impregnated graphite is an excellent self-lubricating anti-wear material, it can be used in high temperature 500°C, deep cold -253°C, high speed 20,000 rpm, high pressure 10Mpa, or high viscosity and other media, it is especially suitable for use under water, oil, kerosene and other media working conditions.

Antimony metal is insoluble in water, hydrochloric acid and concentrated alkali solutions.

Antimony rarely melts when rubbing with steel under the condition of increasing load and speed, therefore, the use of antimony-impregnated graphite material is also suitable for water, hydrochloric acid, concentrated alkali and other media.

The antimony-impregnated graphite material can be silicon carbide, tungsten carbide or stainless steel.
