It is a high tin and aluminum based bush, which adopts steel as backing and is coated a lining of AlSn20Cu through rolling treatment. It is of fairly good fatigue resistance, load capacity and good anti-corrosion and also performs well in bearing’s sliding properties. It is widely applied under high speed and low load such as internal combustion engine, air compressor and cooling machine.
