How to tell the difference between zinc and aluminum alloy for die casting service?
Die casting is one of the most cost-effective, accurate and versatile manufacturing processes in the world today. The main field of die casting industry can be divided into zinc alloy die casting and aluminum alloy die casting, which are widely used in recent years. Then do you know the difference between zinc and aluminum alloys? You’ve come to the right place! Here at Die-casting Mould, we will discuss the difference between zinc and aluminum alloys and comparison of zinc die casting & aluminum die casting. If you want to know more information, make sure to continue reading below!
What Is Zinc Alloy
Zinc alloy is an alloy composed of zinc based on adding other elements. The common alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has a low melting point, good fluidity, easy to weld, braze, and plastic processing, corrosion resistance in the atmosphere, and easy recycling and remelting of residual waste; but its creep strength is low and natural aging is easy to cause dimensional changes. Prepared by melting method, die-casting or pressure-processed into material. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. It can be used for die-casting instrument, auto parts shell electric pole surface galvanized anti-corrosion, boiler water wall pipe hot dip galvanizing treatment to improve high temperature corrosion resistance, etc.
Features of zinc alloy:
● Relatively large.
● Good casting performance, can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
● Can be used for surface treatment: electroplating, spraying, painting, polishing, grinding, etc.
● When melting and die casting, it does not absorb iron, does not corrode the pressure, and does not stick to the mold.
● It has good mechanical properties and wear resistance at room temperature.
● Low melting point, melting at 385℃, easy to die casting.
