1.1 This specification covers zinc master alloys which are used in hot dip galvanizing for the purpose of adjusting the concentration of certain alloying elements in the molten zinc bath. Table 1 covers the chemical composition of these materials which include three master alloys of zinc-aluminum (brightener) and one master alloy of zinc-antimony.
