【China Aluminum Network】 Zinc alloy is an alloy composed of other elements added on the basis of zinc. Often added alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloys have a low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of residuals; however, they have low creep strength and are susceptible to natural ageing causing dimensional changes. Melting method, die casting or pressure processing into the material. According to the manufacturing process can be divided into cast zinc alloy and deformed zinc alloy. Can be used for die-casting instruments, auto parts shell pole surface galvanized anti-corrosion, boiler water wall hot dip zinc treatment to improve high temperature corrosion resistance.

Aluminum alloys are aluminum based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, and lithium. Aluminum alloys are a class of non-ferrous metal structural materials that are widely used in industry and are widely used in aerospace, 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. The zinc alloy is more than 400 degrees, and the aluminum alloy has to go over 700 degrees.

2, different processing equipment, although they are called die casting machine, but it can not be universal.

3, processing technology and parameters are different.

Second, the difference between products

The affinity between zinc alloy and iron is poor, so the draft angle can be made small, generally around 0.5°, while the draft angle of aluminum alloy is generally 1~1.5°.
