Material
Bronze ( DIN-CuZn25Al5Mn4Fe3 )

Introduction
Casting bronze bearings(CuZn25Al5Mn4Fe3), made of bronze CuZn25Al5Mn4Fe3 as base material, are produced by the process of precision machining. They are widely used in the applications of mold, metallurgy and engineering machinery due to the advantages of low friction coefficient, high working temperature and long life.
