Strength
Even at subzero temperatures aluminum remains malleable and stronger than at room temperature. Some aluminum alloys even weaken at an extremely high temperature. For this reason aluminum is often used in outdoor construction. The metal can withstand great wind pressure, making it ideal to use in the construction of research stations in cold weather environments like Alaska.
Non-Corrosive
Aluminum is incredibly resistant to corrosion. It develops a thin layer of oxide between itself and water that prevents it from reacting. This protection comes from aluminum's activity, constantly oxidizing. If the metal becomes corroded, the presence of these chemicals would release a highly flammable hydrogen gas.
Aluminum in Seawater
Aluminum concentrations of dust seeps into water and increases with depth. It occurs as an aerosol on surface levels of water. After collecting trace particles, the dust essentially becomes atmospheric run-off. Aluminum flourishes in the cold of the ocean depths.
Aluminum Production
Producing aluminum alloys involves a process of heating and cooling. After the metal is mined from the earth, it is crushed, filtered and eventually cooled.
