(1) Alloy: An alloy is a substance having a metallic property obtained by fusing two or more kinds of metals (or metals and non-metals). In general, the performance of an alloy is superior to that of a pure metal. The melting point of the alloy is lower than the melting point of its constituent metals, and the hardness is greater than that of its constituent metals. However, the nature of the alloy is not the sum of the properties of the metals of the individual components.

(2) Aluminum alloys Other elements such as copper, magnesium, silicon, zinc, lithium, etc. are added to the metal aluminum to form aluminum alloys having excellent properties.

1 Properties The aluminum alloy has the characteristics of small density, high strength, good plasticity, easy forming, simple manufacturing process and low cost, and the surface is easy to form a dense oxide protective film and has certain corrosion resistance.

2 Applications Aluminum alloys are mainly used in the construction industry, container and packaging industry, transportation and electronics industries, such as the skeleton of automobile wheels, hard disk extraction boxes, etc. In addition, it is also widely used in the manufacture of aircraft components.
