Zinc alloy and aluminum alloy data line which is better?

Aluminum-based alloy. The main alloying elements are copper, silicon, magnesium, zinc, manganese, nickel, iron, titanium, chromium, lithium and other minor alloying elements. Low density aluminum, but the intensity is relatively high, close to or better than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of second only to steel . Aluminum alloy is divided into two categories: casting aluminum alloy, used in the cast; deformed aluminum alloy, can withstand the pressure processing, mechanical properties higher than the as-cast. Machinable into various forms, specifications of aluminum alloy. Mainly used in the manufacture of aviation equipment, daily necessities, such as building windows and doors. Zinc-based alloys with other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and so on. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing. It is corrosion-resistant in the atmosphere and easy to recycle and remelt the scrap materials. However, the creep strength is low and the dimensional change easily occurs due to natural aging. Melt method of preparation, die-casting or pressure processing materials. According to the manufacturing process can be divided into casting zinc alloy and deformed zinc alloy. The main addition of zinc alloy elements are aluminum, copper and magnesium. Zinc alloy according to the processing technology can be divided into two types of deformation and casting zinc alloy casting zinc alloy fluidity and corrosion resistance is good for die-casting instruments, such as automotive parts shell. 【Zinc alloy composition and casting quality】 Zinc alloy characteristics, a large proportion. Second, good casting performance, can die-casting complex shape, thin-walled precision parts, casting surface smooth. Third, the surface can be processed: electroplating, spraying, painting. Fourth, melting and die-casting does not attract iron, non-corrosive pressure type, non-stick mold. Fifth, there is room temperature mechanical properties and wear resistance. Six, low melting point, melting at 5 ℃, easy die-casting molding.
