Bending 11 Gauge Aluminum. The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing. Round tubing 16 gauge. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.
0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. The moduli of elasticity used are 29 700 000 psi for steel and 10 000 000 psi for aluminum.
Bend radii minimum bend sizes.
As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges. Step 2 slide the angle iron into the jaws of the vise so that it lays flat the length of the piece of metal you are going to bend. Formulas and data.
