Antimony-impregnated graphite is a composite material made by impregnating metallic antimony into a graphite matrix, combining
the self-lubricating property of graphite with the density of metals. It features high hardness, excellent wear resistance, superior
thermalconductivity, and stable performance under dry friction or superheated steam media. It is widely used in high-pressure, high-
speedmechanical seals, bearings, and brushes.
High wear resistance: Antimony fills the pores of graphite, enhancing the material's strength and hardness, and significantly improving its
wear resistance.
Self-lubricating: Retains the original low coefficient of friction of graphite.
High temperature resistance / Density: Suitable for high-temperature environments (but the melting point of antimony is around 630°C,
which limits its application in extremely high temperatures), the material is dense and impermeable.
Extensively used in mechanical industries for mechanical seals, sealing rings, bearings, and bushings.
Suitable for dry friction working conditions.
Perform well in steam media.
