The specific strength (strength/density) of aluminum is very high, which means that aluminum alloy components can bear more loads than steel components under the same weight. This is very important for the equipment that pursues the ratio of performance to weight.

A dense and firm aluminum oxide (Al₂O₃) protective film will naturally form on the aluminum surface, which can effectively prevent the internal metal from further oxidation and corrosion. It is especially suitable for mechanical equipment in chemical industry, food, medical treatment and humid environment, which reduces the demand and cost of anti-corrosion treatment such as surface painting and electroplating, prolongs the service life of equipment and ensures the cleanliness of products.

It is suitable for precision instruments, magnetic resonance imaging (MRI) equipment and other occasions that need to avoid magnetic field interference.
