Lead-less assembly alloy with a base of tin incorporating an additional chemical element that forms an intermetallic compound with tin to retard oxidation by air

摘要

A lead-less assembly alloy has a base of tin (Sn) and at least one chemical element chosen from silver (Ag), copper (Cu) and bismuth (Bi) and includes at least one additional chemical element. This additional element is one that retards the oxidation of the alloy in air selected from magnesium, manganese and nickel and is present in a proportion of 0.05 %.wt.
