Aluminum Alloys

Aluminum-base alloys have unique mechanical properties and they are corrosion resistance. These alloys are about one-third density of steel, nevertheless have higher strengths at the same weight ration. Their modulus of elasticity is one third of steel. But with precision design, lighter and stronger properties can be cast with aluminum. Aluminum alloys make a protective layer of aluminum oxide on their surface, which basically prevents them from further corrosion.

Typically, these alloys are subjected to two types of annealing heat treatment and age-hardening.

The most common aluminum alloys are:

• A-357
• A-356
• C-355
• F-357
