关于铝基合金系列中的铝铅轴瓦材料的应用,目前我国尚未开展,因此大家不很熟悉。随着进口机型的逐年增加,主机配套和社会维修所需求的轴瓦材料种类也在不断发展,在近年引进的某些汽车发动机中,已提出了使用铝铅合金材料的要求,轴瓦材料为铸造或锻造铝铅合金复合于钢带上的双金属带,其合金成份为含Pb4～ As for the application of aluminum-aluminum aluminum bearing bush material in the aluminum-based alloy series, at present, our country has not yet carried out, so we are not very familiar with it. With the increase of imported models year by year, the types of bearing bush materials required by the host equipment and social maintenance are also developing. In some automobile engines introduced in recent years, the requirements for using aluminum-lead alloy materials have been proposed. The bearing materials are cast Or forged aluminum alloy bimetal strip on the steel compound, the alloy composition is Pb4 ~
