Bi-metal strip (sheet/plate) backed with high quality low carbon steel and sintering bronze powder on the surface,is forming by several time high temperature sintering and extrusion rolling. Then it can be produced into bushing by blanking, rolling, forming, sizing, tinning and other machining. With excellent wear resistance and good physical and mechanical properties,this kind of bi-metal strip (sheet/plate) is a kind of ideal ease-friction material, applying to producing sliding bearing, thrust washer, lateral plate, bearing bushing and other mechanical components, especially in auto industry. 35kg/bag With Waterproof Paper.
