|Publication Date:||10 May 2002|
|ICS Code (Lead, zinc, tin and their alloys):||77.120.60|
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.
