Abstract
The properties of copper-tin-lead alloys are improved with respect to mechanical resistance and resistance to corrosion by the incorporation therein, in specific proportions of nickel. Antifriction layers on steel supporting strips are obtained by sintering and rolling onto steel strips metal powder particles obtained by powdering a metal alloy of 2-10% nickel, 8-27% lead, 0.5-10% tin and the balance copper.
