Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.
Dec 28, 2015· Titanium vs. Aluminum. 45% Lighter than steel, and 60% heavier than aluminum Because it is so strong and nontoxic, titanium is often used in medical equipment, such as knee replacements, pace makers, cranial plates, and even as the root device for dental implants. Its ability to resist corrosion, on the other hand,...
