Because of an additional 1% copper, #5 zinc alloy has higher hardness and strength than #3 but less ductility which may affect formability. #5 has an excellent castability and a better creep resistance (deformation under high temperature stress). It is also good for electroplating, surface finishing and machining.

Applications

Sports equipment, industrial parts, zippers
