Aluminum Alloy For Bending Sheet Metal

With an addition of 1 manganese these alloys have no significant loss in ductility good corrosion resistance and very good formability.

Aluminum alloy for bending sheet metal. Miserable to bend cracking is very common and cold bending will always weaken the metal. Series 4xxx are the aluminum silicon alloys. Bending is one of the most common sheet metal fabrication operations. The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. As a general rule the machinability of any aluminum alloy is inversely proportional to its formability. The top 3 aluminum alloys for being are the 3003 which has medium strength and the best cold workability the 5052 which is the highest strength alloy of the more common non heat treatable grades and the 6061 which is one of the more versatile heat treatable alloys. This is done through the application of force on a workpiece.

3003 definitely isn t fun for drilling or any other sort of operation involving edge cutting tools. Wildly variable unless you know the exact alloy. Series 3xxx are the aluminum manganese alloys. The alloy 5052 h32 may bend well enough for my use and shows about 50 higher tensile and yield.

4140 is usually pretty malleable in general you ll always want it to be annealed if you re planning on bending it or else it ll crack. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx.
