摘　　要：研究了一种以铝为基体，加入7％的锡，并适量添加铜、镍、钛、硼等合金元素的新型铝基滑动轴承合金。结果表明，该合金的性能特点为：σb为195—207．5MPa，魂为5．4％-6．3％，硬度为72～76HBS，其强度和塑性不低于ZQSn6-6-3锡青铜的水平，硬度略高于ZQSn6-6—3锡青铜；并具有优良的耐磨性、减摩性和抗咬合性等滑动轴性能，适合用于制造整体材质的轴瓦、轴套等机械零件。The experiment research deals with the usage performance of a kind of aluminum alloy during nature aging. The alloy comprises 7% of stannum and appropriate cuprum, nickel, titanium , boron etc. The test results show that the alloy＇ s tensile strength ranges from 195MPa to 207.5MPa,breaking elongation percentage （ 85 ） ranges from 5.4% to 6. 3%, hardness ranges from HBS72 to HBS76,its strength and plasticity is not lower than that of ZQSn6-6-3 tin bronze alloys, its hardness is little better than that of ZQSn6- 6-3 tin bronze alloys; further more.9,it has excellent wear resistance , friction-reduce ability and anti-seizure property. It is suitable for making mechanical components such as unitary-material bearing shells.
