Bending 2mm Aluminium Sheet

Protocase tech tip video.

Bending 2mm aluminium sheet.

This weakens the aluminium and creates a fracture line. If you re bending 0 020 thick material use a 0 020 radius. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

Place the fracture line over the edge of a table and bend the overhang slightly downwards. The force must exceed the material s yield strength to achieve a plastic deformation. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. This is done through the application of force on a workpiece.

Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Medium strength alloy work hardens rapidly. Quick video about bend radius watch more tech tip videos bend radii minimum bend sizes.

Calculate the force required to fold 800 mm from sheets of 3 mm aluminium 25 kg mm2. The finer the marks the more accurate your bends and cuts will be. Magnetic sheet metal brake can bend items impossible for traditional box and pan brakes such as totally enclosed boxes triangles alternate bends on varyin. Bending is one of the most common sheet metal fabrication operations.

This doesn t sound like a lot but when you are drilling four holes to mate up to another piece its important. Aluminium grades 5251 h22. 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. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Bend radii minimum bend sizes. With a 2mm line you could be out of square by 2mm or the hole you just drilled is off 2mm.
