Zinc alloy is an alloy based on zinc and other elements. Commonly added alloying elements include low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has a low melting point, good fluidity, and is easy to weld, braze and process plastics. Also, in the atmosphere, zinc alloys are highly corrosive and easy to recycle. Material made by melting method, die casting, or pressure processing.
Advantages of Zinc alloy:
Good casting performance. It can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
Various surface treatments are available. E. g: 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 abrasion resistance at room temperature.
Low melting point. Melty at 385°C, easily die-casting.
B. Aluminum Alloy
Aluminum alloy is the most widely used non-ferrous metal structural material in the industry and used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, and chemical industries. With the rapid development of the industrial economy, the demand for pressure cast aluminum and aluminum alloy welded structural parts is increasing, and the weldability of aluminum alloy also study in-depth.
Advantages of Aluminum Alloy:
The density is small. The density aluminum alloy is close to 2.7g, about 1/3 of that of iron or copper.
Aluminum alloy has high strength. After cold working, it will increase. Heat treatment is strengthening other grades of aluminum alloy.
Good electrical and thermal conductivity. The electrical and thermal conductivity of aluminum is second only to silver, copper, and gold.
Good corrosion resistance. The aluminum surface is prone to naturally produce a dense and strength AL2O3 protective film, which can protect the substrate from corrosion. Through artificial anodic oxidation and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can obtain.
Easy to process. After adding certain alloying elements, a cast aluminum alloy with good casting properties or a deformed aluminum alloy with good processing plasticity can obtain.
The differences between zinc and aluminum alloy as below chart:
Everyone who sees here has already felt the difference between zinc alloy and aluminum alloy. Each has its advantages and disadvantages. Should choose the material suitable for your product according to the quality, technology, life, and other product requirements. As a professional casting parts manufacturer, EMP insists on producing according to customer needs and using the highest quality and most suitable materials.
