The difference between zinc alloy and aluminum alloy

【China Aluminum Industry Network】 Zinc alloy is an alloy composed of zinc and other elements. Often added alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloys have low melting points, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of residual wastes; but low creep strength, easy to attack natural aging leads to scale changes. Melting method, die casting or pressure processing into the material. According to manufacturing technology can be divided into forged zinc alloy and deformed zinc alloy. Can be used for die-casting appearance, car parts housing pole pole galvanized anti-corrosion, boiler water-wall hot dip galvanized pipe to improve the performance of high temperature corrosion.

Aluminum alloys are aluminum based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and non-essential alloying elements include nickel, iron, titanium, chromium, and lithium. Aluminium alloys are a type of non-ferrous metal structural materials that are widely used in the industry and are used in many fields such as aviation, aerospace, cars, machinery manufacturing, ships, and chemical industries.

First, the technical differences in die casting are as follows:

1, the melting temperature of the two alloy processing is not the same, the zinc alloy in 400 degrees, the aluminum alloy to go to more than 700 degrees.

2, processing equipment is not the same, although they are called die casting machine, but completely can not be universal.

3, processing technology and parameters are not the same.

Second, the differences in the goods

The affinity of zinc alloy and iron is poor, so the draft can be made very small, usually about 0.5°, while the draft of aluminum alloy is usually 1~1.5°
