Die Casting Zinc Alloys Zamak. Zinc alloy is preferred by most people in the metal making industry especially in die casting for many reasons. The most popular of the reasons is the fact that zinc has a low melting point. It means that it does not require a very high temperature in order for it to turn into its liquid state. This characteristic makes it easier to be casted.
Another reason why zinc alloy is preferred is that this metal is durable and takes a long time before it actually deteriorates. It is highly ductile and can be casted into different shapes and sizes. It can withstand huge amounts of pressure. However, in order that such qualities of zinc be retained, it is necessary that the other metals mixed with it are limited. Hence, other metals such as lead and tin must be used in moderation.
These outstanding characteristics of die casting zinc alloys made it a top choice of producers in many industries such as automotive, medical equipments and household appliances.
Die casting zinc alloys are not only limited to a single type. Zinc alloys are also known as Zamak in the industrial world. Zamak is an acronym that stands for zinc, aluminum, magnesium and copper. Zinc comes in various types with different levels depending on the output desired. Die Casting Zinc Alloys are classified as Zinc #2, Zinc #3, Zinc #5, and Zinc #7. The other classification of zinc alloy is ZA or the zinc-aluminum alloy. It is further classified into ZA-8, ZA-12, and ZA-27.
