Aluminum alloys of resistance to wear high and having good pharmacological anti - seizing, for the bearings and bearings

摘要

P the invention described in the alloys obtained by adding of 0,01 - 3 by weight of at least one element of the alloy chosen from the group of mn, v, cr, ti, mg and was of the alloys for the bearings of the system a1 - - - pb, sn, cu of the prior art [0002]. By adding at least one of these elements of the alloy, it is possible to improve the resistance of the wear and the pharmacological anti-seizure of the alloys in bearings in order to satisfy the requirements created by increasing the speed and the load of the internal combustion engines. / p
