Abstract
A silver/palladium alloy for electrical contact applications comprises, on a weight percent basis, 20-50 silver, 20-50 palladium, 20-40 copper, less than 1.0 nickel, 0.1-5 zinc, 0.01-0.3 boron, and up to 1 percent by weight of modifying elements selected from the group consisting of rhenium, ruthenium, gold, and platinum. The combination of zinc and boron provides an alloy of high strength and hardness and permits the use of lower amounts of both copper and palladium.
