The invention relates to antifriction alloys YPbSn10Ca and YPbSn10Mg with superior properties in comparison with the commercial alloy YPbSn10. For this invention we used Ca and Mg due to the fact that they present a low toxicity. These elements could segregate at the grain dimensions/ dendrites and reducing interface energy grain/dendrite, stopping the movement or grain slipping.
