Bending 11 Gauge Aluminum

304 stainless steel 18 gauge.

Bending 11 gauge aluminum.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Use at your own risk. Round tubing 16 gauge.

Formulas and data. The moduli of elasticity used are 29 700 000 psi for steel and 10 000 000 psi for aluminum. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. I fabricated a small bending brake using plans from the miller welding web site and it will bend 1 5 wide 125 thick steel.

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. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing.

If the deflection is large enough to permanently bend the tube then all bets are off. The gauge system has long history in metal fabrication. Round tubing 18 gauge. Bend radii minimum bend sizes.

You will use the protractor to gauge the brake as you bend the metal little by little. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. 304 stainless 11 12 gauge.

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. Round tubing 14. Keep in mind that some metals are more brittle than others. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Bending a brittle metal beyond its limits could cause the metal to snap and break. Or you ll be sorry. History of the gauge system. Mild steel 18 gauge.

Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Aluminized steel 14 gauge. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

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.
