MATERIAL ON AN ALUMINIUM BASIS FOR ANTI-FRICTION BEARINGS

摘要

The invention relates to a material on an aluminium basis used for anti-friction bearings and consisting of an aluminium alloy containing between 10 and 25 percent by weight tin or between 5 and 25 percent by weight lead as well as constituents due to contamination. To obtain an aluminium alloy which has good deformation behaviour and high fatigue resistance and is economical to produce said alloy contains between 0.75 and 2.5 percent by weight iron and alloying additions of a) manganese and silicon, whereby the percentage by weight of manganese and silicon is at least half the percentage by weight of iron, but no more than 3 percent by weight for manganese and no more than 2 percent by weight for silicon; or b) between 0.1 and 0.5 percent by weight cobalt or molybdenum.
