Aluminium casting alloy main elements

There are six property elements that compose the alloys, these include:

1.Silicon

Second to iron, this element contains the greatest impurity level in electrolytic commercial aluminum (0.01 to 0.15%).

2.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.

3.Magnesium

Maximum solid solubility is 17.4%. The addition of magnesium shows an increase in the strength of aluminum without unduly decreasing the ductility.

4.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.

5.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.

6.Zinc

Alloys containing a blend of Zinc and other elements will provide the best mix of tensile properties.
