Abstract
Castings made from aluminum and its alloys have at least one face including at least one region of wear-resistant zones. These castings are formed by a controlled distribution of zones hardened by local melting effect. The zones, no matter what their length and shape, have a width and depth between 3 and 150 .mu.m and the surface fraction or percentage of the zones for the wear-resistant region is between 5 and 60%.
