Bending Aluminium Sheet

Place the fracture line over the edge of a table and bend the overhang slightly downwards.

Bending aluminium sheet.

Say you re bending 0 25 in thick 6061 t6 aluminum to a 100 degree external angle 80 degree internal angle. Die opening with a relieved profile. To calculate the expansion that will take place on the outside of your bend angle you will need to know your bend allowance. To make this easier you d start with your 6061 material in the soft t 0 state.

Flip the sheet over and repeat. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. The bending you will be doing will warp your sheet metal so that it is physically bigger. A bending brake is a specialized metalworking.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. Insert your aluminum sheet into the brake beneath the removable clamp bar. This weakens the aluminium and creates a fracture line.

Lift the clamp bar away from the rear of. You d probably air bend by using a 3 0 in. Purchase a metal bending brake online or at your local hardware store.
