ABSTRACT:
An aluminum bearing-alloy containing 1.5 to 8 mass % of Si is provided, in which there can be observed Si grains on the sliding surface of the aluminum bearing-alloy. A fractional area of the observed Si grains having a grain size of less than 4 μm is 20 to 60% of a total area of all the observed Si grains. Another fractional area of the observed Si grains having a grain size of from 4 to 20 μm is not less than 40% of the total area of all the observed Si grains.
