Aluminum properties

Aluminum performance of magnesium-plated aluminum plate The electrical conductivity of aluminum is second only to silver and copper, and it is widely used in electrical equipment and high-voltage cables. Aluminum is one of the best reflectors of heat and light (including ultraviolet light), so it is used as a thermal insulation material and as a mirror in reflecting telescopes. The reflective lenses in the world's largest telescopes are made of spray-painted aluminum. Aluminum can be used to make aerospace components to reduce the harm of ultraviolet light to the body. The inner layer of a space suit is made of eight layers of chemical fiber textile coated with metallic aluminum. Aluminum also has excellent sound insulation effect. Some broadcast rooms and suspended ceilings of large and medium-sized engineering buildings use aluminum for sound insulation. Aluminum still has very good strength and mechanical properties in low-temperature environments. Therefore, aluminum can not only be used as equipment for transporting and storing refrigerated food, as well as building materials in cold areas, but it can also be used as liquid hydrogen and liquid in rockets. Oxygen storage tank and other parts. Aluminum becomes a superconductor at temperatures below 2 Kelvin. Aluminum plays a great role in engineering construction. Aluminum has excellent corrosion resistance. The Parliament Building in the Kremlin in Paris was created using aluminum and laminated glass. At present, aluminum alloy profiles have been used in bridges, commercial buildings, aircraft hangars and underwater construction.

Many transportation special tools are made of aluminum. Aluminum is also widely used in defense technology. Ships made of aluminum are not only faster and not corroded by the sea surface, but are also non-magnetic and can prevent magnetic raids.
