Alpha brass is an alloy of Brass that contains less than 38% of Zinc. The zinc is dissolved in the Copper and the alloy has the same structure as copper. Alpha brass is ductile, has high tensile strength and can be cold-worked. Most ancient brasses do not contain over 28% zinc as this was the proportion that was adsorbed by the copper when the zinc ore was reduced (Scott, 1991).
