Aluminum alloys are ideal for high impact applications. Due to the general light weight, these AL alloys are able to provide weight reduction in die cast parts while being resilient enough to absorb extremely high operation climates. The overall alloy properties can very with each combination at Die Castings China, but the general property of Aluminum alloy does include an elevated surface toughness, strength, wall rigidness and heat transfer ability.
What are the elements used to create this Aluminum casting alloy?
There are six property elements that compose the alloys, these include:
- Silicon – Second to iron, this element contains the greatest impurity level in electrolytic commercial aluminum (0.01 to 0.15%).
- Copper – AL material types will normally mix 2 to 10% of copper. This type of element will allow the alloy to react to solution heat treatment and subsequent aging with an increase in strength and hardness and a decrease in elongation.
- Magnesium – maximum solid solubility is 17.4%. The addition of magnesium shows an increase in the strength of aluminum without unduly decreasing the ductility.
- Iron – the most common element found in Aluminum. It has a high solubility in molten aluminum and is easily dissolved at all molten stages of production.
- Manganese – common element in which its concentration ranges from 5ppm – 50ppm. Manganese decreases resistiveness while increasing strength in both solid solutions and precipitated intermetallic states.
- Zinc – alloys containing a blend of Zinc and other elements will provide the best mix of tensile properties.

Please reference the chart below to learn more about the properties of A380, ADC12, ADC6, ALSi10Mg, ALSi12Fe, ALSi9Cu3, ALSi12Cu1Fe, ALSi12CuNiMg and ALSi12Cu2. Each type of AL will offer significant advantages for Engineers and Manufacturers in different industry applications.
A380 / ADC10 / AlSi8Cu3Fe
A380 is the most popular and common choice for die casting. A380 is known for offering an ideal combination efficient material properties and production workability. In addition, this material type is commonly used by industry applications throughout the World.
A383 / ADC12
A383 / ADC12 alternatives to A380 for intricate components requiring improved die filling characteristics. Alloy 383 offers improved resistance to hot cracking (strength at elevated temperatures).
A360 / ADC3 / ALSi10Mg
A360 / ALSi10Mg offers higher corrosion resistance, superior strength at elevated temperatures, and somewhat better ductility, but is more difficult to cast. While not in wide use and difficult to cast, alloy 43 (ANSI/AA C443.0) offers the highest ductility in the aluminum family. It is moderate in corrosion resistance and often can be used in marine grade applications.
ALSi12Fe / A413
ALSi12Fe or A413 offers excellent pressure tightness, making it a good choice for hydraulic cylinders and pressure vessels. Its casting characteristics make it useful for intricate components.
A514 / ADC6
A514 / ADC6 provides the best combination of strength, ductility, corrosion resistance and finishing qualities, but it is more difficult to die cast.
