Aluminum Flat Bar 2024 is alloyed with 4.5% copper. Tensile Strengths range from 30,000 psi to 63,000 psi. It offers high strength. Corrosion resistance and workability are fair. Forming operations are also limited. The alloy is heat treatable to obtain several levels of strength depending upon the temper.  6061 is one of the most common alloys of aluminum in use today. It combines workabilty, weldability, and corrosion resistance into one alloy with medium strength. Can be used for all types of applications. 6061 alloy is heat treatable to attain higher hardness.
