Overview
Technical Parameter
This product is based on a high-density copper alloy with a special formula, with a porous bronze layer sintered in the middle, and a mixture of polytetrafluoroethylene (PTFE) and lead (Pb) rolled on the surface. It can provide good self-lubricating, wear-resistant, low friction and other properties, fully utilizing the advantages of metals and multi-element polymers.
