AE Casting uses a variety of alloys to achieve different properties in the final product. The most common alloys consist of about 95 percent zinc, a few percent aluminum, and smaller amounts of copper and magnesium. Which Alloy is best for a product depends on the properties of the end product. Zamak is a group of the most common zinc alloys. The latest in Zamak is the Ezac brand. It is a specially developed alloy of zinc that has better properties than other alloys in several areas. The Alloy has better creep resistance, higher tensile strength and is stronger. We Use this alloy when a product must meet high requirements.
