Zinc alloys are alloys based on zinc and added to other elements.Have added alloying elements are low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing. It is resistant to corrosion in the atmosphere, and the residual waste is easy to recover and remelt; but the creep strength is low, and it is easy to cause dimensional changes caused by natural aging. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. It can be used for die casting instruments, galvanized anti-corrosion on the surface of electric poles of automobile parts, hot-dip galvanizing treatment of pots and cold-walled pipes to improve high-temperature corrosion resistance.

The main alloying elements of aluminum alloy are copper, silicon, magnesium, zinc and manganese. The secondary alloying elements are nickel, iron, titanium, chromium and lithium. Aluminum alloy is one of the most widely used non-ferrous metal structural materials in the industry, and is widely used in aviation, aerospace, automotive, machinery manufacturing, marine and chemical industries.

First, the difference in die casting process is as follows:
1. The melting temperature of the two alloys is different when processing, the zinc alloy is more than 400 degrees, and the aluminum alloy is going to more than 700 degrees.
2, different processing equipment, although they are called die casting machines, but can not be used at all.
3. Processing technology and parameters are different.
