Description

P/M antifriction material is material finished via powder metallurgy technology after adding lubricating components or sintering porous basis skeleton and impregnating liquid lubricating component. It can be divided into copper-base antifriction material and composite self-lubricating material, which is used in parts reducing friction, such as, bearing, wearing pad etc.
