American Standard Aluminum Wide Flange Beams

6061 is the least expensive and most versatile of the heat-treatable aluminum alloys. It has most of the good qualities of aluminum. It offers a range of good mechanical properties and good corrosion resistance. It can be fabricated by most of the commonly used techniques. In the annealed condition it has good workability. In the T4 condition fairly severe forming operations may be accomplished. The full T6 properties may be obtained by artificial aging. It is welded by all methods and can be furnace brazed. It is available in the clad form ("Alclad") with a thin surface layer of high purity aluminum to improve both appearance and corrosion resistance. Applications: This grade is used for a wide variety of products and applications from truck bodies and frames to screw machine parts and structural components. 6061 is used where appearance and better corrosion resistance with good strength are required.

¹ Based on 500,000.000 cycles of completely reversed stress using the R. R. Moore-type of machine and specimen. ² Average of tension and compression moduli. Compression modulus is about 2 percent greater than tension modulus. ³ Ratings A through E are relative ratings in decreasing order of merit, based on exposures to sodium chloride solution by intermittent spraying or immersion. Alloys with A and B ratings can be used in industrial and seacoast atmospheres without protection. Alloys with C, D and E ratings generally should be protected at least on faying surfaces. ⁴ Ratings A through D for Weldability and Brazeability are relative ratings. ⁵ A = Generally weldable by all commercial procedures and methods. B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance. C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties. ⁶ A = Generally weldable by all commercial procedures and methods. B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance. C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties. ⁷ A = Generally weldable by all commercial procedures and methods. B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance. C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
