    Zinc processing The metal and its alloys | Britannica

    At 40 to 45 percent zinc, the solidified alloys form mixed alpha and beta phases, in which hot plasticity is followed on cooling by reasonable cold-working properties. These are used in casting, hot-pressing, and extruding. The brasses have high strengths, good corrosion resistance, and good electrical conductivity.

    Engineering Characteristics Zinc Die Casting

    Zincalloys can be diecastwith less draft angle than competitive materials. In fact,zinccomponents can sometimes becastwith zero draft angles which is a major advantage when producing parts in moving mechanical contacts such as gears. Zero internal draft permits net shape manufacturing resulting in lower cost production.
