Aluminum alloy is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the minor alloying elements are nickel, iron, titanium, chromium, and lithium. Aluminum alloy is the most widely used type of non-ferrous metal structure material in industry. It is widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries.
Zinc alloy is an alloy composed of zinc and other elements. The alloying elements often added are low temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of residues; however, its creep strength is low and it is easy to cause dimensional changes due to natural aging. Zinc alloy is prepared by melting method, die-casting or pressure processing. 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 anticorrosion on the surface of automobile parts' housings, electric poles, and hot-dip galvanizing treatment of boiler water-cooled wall pipes to improve high-temperature corrosion resistance.

The differences in the die casting process of aluminum alloy and zinc alloy are as follows:
1. The molten soup temperature is different when the two alloys are processed. The zinc alloy is more than 400 degrees, and the aluminum alloy must be more than 700 degrees.
2. The processing equipment is different. Although they are all called die-casting machines, they cannot be universally used.
3. The processing technology and parameters are different.

Difference between mechanical properties of aluminum alloy and zinc alloy
Zinc alloy hardness 65-140, tensile strength 260-440
Aluminum alloy hardness 45-90, tensile strength 120-290
The overall zinc alloy has higher hardness and higher tensile strength than aluminum alloy.
