Bending 11 Gauge Aluminum

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

Bending 11 gauge aluminum.

Typically i bend 12 15 widths of 18 gauge steel. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Mild steel 10 11 gauge.

Formulas and data. I think a small press brake will do what you want it depends on the width of the aluminum. I fabricated a small bending brake using plans from the miller welding web site and it will bend 1 5 wide 125 thick steel. The moduli of elasticity used are 29 700 000 psi for steel and 10 000 000 psi for aluminum.

The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing. The gauge system has long history in metal fabrication. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Each aspect of sheet metal bending is important to consider when determining the proper tonnage for the desired bend. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

Round tubing 16 gauge. Bend radii minimum bend sizes. Round tubing 18 gauge. History of the gauge system.

Aluminized steel 14 gauge. If the deflection is large enough to permanently bend the tube then all bets are off. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts.

Round tubing 14. 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. 304 stainless 11 12 gauge. Sep 30 2015 determining the proper tonnage for air bending a piece of sheet metal or a heavy plate will depend on a couple of variables.

Or you ll be sorry. Bending a brittle metal beyond its limits could cause the metal to snap and break. You will use the protractor to gauge the brake as you bend the metal little by little. Use at your own risk.
