2024 Aluminum: High
strength, fatigue-resistant for structural applications in motorsports
and aircraft industries. Good corrosion resistance
in non-industrial, poor for marine use. Good machinability.
3003 Aluminum: General
purpose aluminum, moderate strength, good workability and weldability,
excellent corrosion resistance; non-heat treatable, may be deep drawn,
welded or brazed.
5052 Aluminum: Highest
strength grade of aluminum of non-heat-treatable alloys; higher fatigue
strength, excellent resistance to salt water atmosphere, excellent
weldability and workability, and excellent finishing characteristics.
6061 Aluminum: Good formability, weldability, high corrosion resistance; the most economical of the heat-treatable aluminums.
6063 Aluminum: Architectural alloy, developed primarily for extrusions, relatively high
tensile properties, excellent finishing characteristics, and high
corrosion resistance.
7075 Aluminum: One of
the highest strength aluminum alloys used for highly stressed parts
where strength is extremely critical, good machinability, excellent
strength-to-weight ratio, only average corrosion resistance; improve
resistance is normally obtained by cladding parts. Sometimes used in
place of 2024.
