Aluminum has an outstanding strength-to-weight ratio and is easy to form. Its natural corrosion resistance, which can be increased with anodizing, is one of the biggest benefits. Aluminum coil is found in a range of applications from housing siding, trim, gutters, and roofing to cans, lids, caps, bottles, and other food packaging, appliances and electronics. Because it is a lightweight and durable material, it is also seen in the automotive industry.
The density of aluminum is very small, only 2.7g /cm³. Although it is soft, it can be made into a variety of aluminum alloys, such as duralumin, superduralumin, rustproof aluminum, cast aluminum and so on. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries. In addition, space rockets, space shuttles,satellites also use a large number of aluminum and its aluminum alloy.
