Aluminum casting alloys are one of the most preferred used foundry alloys in different industries because they introduce excellent properties, A356 aluminum casting alloys are one of Al-Si alloys and widely used in automotive and aircraft due to the superior properties such as low density, high strength to weight ratio, high corrosion resistance, good impact resistance, good thermal conductivity, excellent castability, and high wear resistance.

In the aluminum casting industry, the 3xx.x series alloys are widely used. The primary alloying element in the 3xx.x series alloys is silicon, where the addition of the silicon leads to increase fluidity and strength. The high hardness of the primary silicon phase leads to reducing the machinability of aluminum alloys, thus generally the silicon content in the aluminum alloy will not exceed the eutectic point (silicon content 12.6 percent to avoid the formation of the hard-primary silicon phase. The zinc oxide is a multi-functional material because of the unique chemical and physical properties such as high electrochemical coupling coefficient, high chemical stability, radiation absorption, and high photo-stability. The various methods for ZnO production were studied and the most common and cost-effectiveness method is the microwave-assisted hydrothermal route. Aluminum’s strength, corrosion resistance, and heat-dissipating properties offer mechanical designers’ significant advantages. And our proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for even more applications.

Advantages of Aluminum Die Casting

One of the most significant benefits of aluminum die casting is that it creates lighter parts—with more surface finishing options than other die cast alloys. Aluminum can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast aluminum is versatile, corrosion-resistant; it retains high dimensional stability with thin walls and can be used in almost any industry.

Recycling Aluminum Die Casting

Did you know that over 95 percent of aluminum castings alloys made in North America are made of post-consumer recycled aluminum? There is extraordinarily little functional difference between primary (extracted or pure) and secondary (recycled) Recycling Aluminum Die Casting. Secondary aluminum casting alloys are derived from mixing and melting pure aluminum with other materials such as magnesium, iron, and copper. The use of pure aluminum in casting is quite rare due to the cost of extraction. The ease of use in die casting combined with lighter weight and durability make aluminum alloys a top choice for designers from nearly any industry.

Secondary aluminum is more economical to produce than primary aluminum because it only requires 5 percent as much energy to produce. Most of the energy consumption in aluminum die casting is used to heat and re-melt the metal during fabrication. For this reason, some companies are able to save more time, energy, and money by re-melting in-house.
