Aluminum Types and Aluminum Welding
Characteristics Aluminum alloys are used in engineering design chiefly for their light weight, high strength to weight ratio, corrosion resistance, and relatively low cost. Aluminum is the most widely distributed of the elements, except for oxygen, nitrogen, and silicon. Aluminum alloys weigh about 0.1 pound per cubic inch. This is about one third the weight of iron at 0.28 pounds and copper at 0.32, is slightly heavier than magnesium at 0.066, and somewhat lighter than titanium at 0.163.
