Between 38 and 46% zinc, the alloy is a two-phase structure, and is known as beta phase. With more than 50% zinc, another solid solution called gamma is found. The beta and gamma solid solutions are not as ductile as the alpha solid solution; therefore, very few alloys containing more than about 40% zinc are of commercial importance.
