How important is aluminum?

1. Aluminum has good ductility (its ductility is second only to gold and silver), and it can be made into aluminum foil thinner than 0.01mm at 100 ℃ ~ 150 ℃. These aluminum foils are widely used for packaging cigarettes, candies, etc., and can also be made into aluminum wires and bars and can be rolled into various aluminum products.

2. Due to the dense oxide protective film on the surface of aluminum, it is not easy to be corroded, and it is often used to manufacture chemical reactors, medical equipment, refrigeration equipment, petroleum refining equipment, oil and gas pipelines, etc.

3. Low temperature resistance, when the temperature of aluminum is low, its strength increases instead of brittleness, so it is an ideal material for low temperature devices, such as refrigerators, freezers, Antarctic snowmobiles, and hydrogen oxide production devices.

4. Aluminum has sound-absorbing properties, and the sound effect is also good, so aluminum is also used in the ceilings of broadcasting rooms and modern large-scale buildings. #aluminum
