Aluminum Alloys
Aluminum is used for an enormous range of products such as kitchen
utensils and soft drink cans. Aluminum alloys are used for skins and
frames of aircrafts. Cast alloys of aluminum and silicon are widely used
for automobile engine block materials, as they are strong, light, and have
good corrosion and wear resistance. The strength-to-weight ratio of
aluminum alloys can be improved by adding lithium. Lithium is the
lightest of all metals, so by adding lithium, the final alloy would be
lighter. However, the portion of aluminum alloys used in aircrafts is
decreasing because more composite and other materials are used.
