Aluminum properties

Aluminum is valued for its low density and resistance to corrosion (due to passivation). Structural parts made from aluminum and its alloys are critical not only in the aerospace industry, but also in the fields of transportation and structural materials. The most useful aluminum compounds are its oxides and sulfates. Despite the widespread presence of aluminum in the environment, none of the life forms contain aluminum-containing salts. Corresponding to the ubiquity of aluminum, animals and plants are well tolerant to it. [6] The potential benefits and biological roles of aluminum compounds are receiving increasing attention.

For nearly fifty years, aluminum has become one of the most widely used metals in the world. In the construction industry, aluminum is widely used due to its stability in air and excellent appearance after anodizing; aluminum alloy materials are also widely used in aerospace and defense industries; high-strength steel wires are commonly used in power transmission. Reinforced aluminum cables are used in some places because copper cables are often stolen due to their high prices; container transportation, daily necessities, household appliances, mechanical equipment, etc. require a large amount of aluminum.
