The density of aluminum is very small, only 2.7 g/cm. Although it is relatively soft, it can be made into various aluminum alloys, such as hard aluminum, super hard aluminum, rust-proof aluminum, cast aluminum, etc. Aluminum has good ductility, which enables it to roll various aluminum products such as aluminum wire aluminum strip. The surface of aluminum is not easily corroded due to its dense oxide protective film. Aluminum has silvery white luster and anti-corrosion performance. The reflection performance of aluminum to light is also very good. The reflection ultraviolet ray is stronger than silver. The purer aluminum is, the better its reflection ability is. Aluminum has sound absorption performance and good sound effect, so the broadcasting room and the ceiling of modern large buildings are also made of aluminum. Low temperature resistance. When the temperature of aluminum is low, its strength increases without brittleness. Therefore, it is an ambitious material for cryo equipment. These advantages of aluminum enable aluminum strip as aluminum products to be competent for the important task of hollow aluminum gutter. Why hollow glass uses hollow aluminum strip.
