Mar 16, 2011· White metals (SnPbCuSb) are extensively used as materials of journal bearings made of tin and leadbased alloys. We study the tribological and mechanical properties of the journal bearings manufactured from Snbased SnPbCuSb, pure Sn, pure Pb, alloy elements, and pure Cu metals. A shaft of SAE1050 steel (journal) was used as a counter abrader.
