Choosing Between the Three Common Aluminum Alloys

Choosing Between the Three Common Aluminum Alloys

Probably one of the most common aluminum alloys being used, 2024 aluminum alloy displays high strength and good workability and formability. It’s corrosion resistance, however, is considered poor compared to most other alloys.

In general, aluminum alloy 6061 is considered by many to be highly versatile, and more so that aluminum alloy 7075, for a wide variety of general purpose mechanical applications. It is highly weldable and workable.
aluminum alloy 7075, on the other hand, is one of the strongest aluminum alloys available and 7075 alloys are worth the typically higher cost when strength and toughness are crucial.
While aluminum alloy 7075 is less workable than 6061, if strength is the most crucial consideration, then 7075 is probably the better choice. If you need an alloy that is weldable, machinable and offers great versatility, go for the 6061 aluminum alloy. And, if you need both workability and high strength, and welding nor corrosion resistance is needed, then 2024 is your choice.
