A New Aluminum-Based Bearing Alloy for Slide Type Antifriction Bearings 932903
A new aluminum alloy named 1531 is described. It has been specifically designed for journal bearings of the new families of automotive engines expected to be produced in the second half of the nineties.
This new alloy, based on the Al-Sn-Si system, offers improved characteristics as regards resistance to dynamic loading and to wear, in comparison with conventional AlSn20 alloys now used.
The foreseen technological production process makes such alloy competitive to overplated Cu-Pb alloys.
