Abstract (en)
[origin: WO2022073575A1] The invention relates to an electrically conducting material (1) comprising a substrate (10) of copper or a copper alloy and a coating (2) of at least one layer (21, 22), wherein the coating (2) has an outermost layer (21) of which at least 90% by volume consists of an intermetallic phase (41) which comprises or is Cu6Sn5. According to the invention, the surface of the outermost layer (21) facing away from the substrate (10) has isolated silver-rich precipitates (3) covering a proportion of the surface area of 7 to 20%.
