An alloy of aluminum?
1. Definition of alloy- A metal alloy is a substance that is formed by the combination of more than one metal or by mixing one metal with other non-metallic elements. In the alloy of aluminum, aluminum is said to be a predominant metal and the other elements are added to it.
2. The alloy of aluminum is made by mixing together the elements when aluminum is molten (liquid), which cools to form a homogeneous solid solution.
3. The elements that can be added are iron, copper, magnesium, silicon, and zinc.
4. The addition of elements to the aluminum gives the alloy improved strength, workability, corrosion resistance, electrical conductivity, and/or density, compared with the pure metallic element.
5. So therefore an alloy of aluminum is known as Duralumin.
6. Duralumin is an alloy of aluminum (90%), 4% of copper (Cu), 1% of Magnesium (Mg), and 0.5% - 1% manganese (Mn).
