The difference between zinc alloy and aluminum alloy

Zinc alloy is an alloy based on zinc and composed of other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low temperature zinc alloy. Zinc alloy melting point is low, good liquidity, easy to weld, brazing and plastic processing, corrosion resistance in the atmosphere, waste material is easy to recover and remelting; However, the creep strength is low and the size change is easily caused by natural aging. It is prepared by melting, die casting or pressure machining. According to the manufacturing process can be divided into cast zinc alloy and deformation zinc alloy. It can be used for die-casting instrument, automobile parts shell, electric pole surface galvanized anti-corrosion, boiler water wall pipe hot dip zinc treatment to improve high temperature corrosion resistance, etc.

Aluminum alloy is based on aluminum alloy general name. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy is one of the most widely used nonferrous metal structural materials in industry. It is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry.


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


1, two kinds of alloy processing molten temperature is different, zinc alloy in more than 400 degrees, aluminum alloy to go to more than 700 degrees.


2, processing equipment is different, although called die casting machine, but completely can not be used.


3. Different processing technology and parameters.


Second, the difference on the product


The affinity of zinc alloy and iron is poor, so the die slope can be made very small, generally about 0.5°, and the aluminum alloy die slope is general
