The difference between zinc alloy and aluminum alloy

According to Jiahangaero learned that zinc alloy is an alloy composed of zinc as the base and adding other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is easy to recycle and remelt; but the creep strength is low, and it is prone to dimensional changes caused by natural aging. 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.Jiahangaero can be used for die-casting instruments, galvanized anti-corrosion on the surface of utility poles for automobile parts shells, hot-dip galvanizing treatment for boiler water-cooled wall pipes to improve high-temperature corrosion resistance, etc.

Aluminum alloy is a general term for alloys based on aluminum. Jiahangaero states that the main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry.

The differences in die casting process are as follows:

• The melting temperature of the two alloys is different during processing. The temperature of the zinc alloy is more than 400 degrees, and that of the aluminum alloy is more than 700 degrees.

• The processing equipment is different. Although they are all called die-casting machines, they cannot be used universally.

• The processing technology and parameters are different.
