It is bimetal bush with steel as backing and sintered CuPb30 as lining layer. It has good performance in anti-seizing, alien substance contamination. It is necessary to be overplated certain soft alloy and mostly applied in intermal combustion engine under high speed and middle to low load, e.g.main bush and connect-rod bush.
1. Chemical compositions: CuPb30. 2. Max load capacity: 25N/mm2. 3. Tempearture max: 170℃. 4. Alloy Hardness: (30~45)HB.
