Bending alumiinum sheet metal. 6061 t6 aluminum is tempered and notorious for not bending easily. Place the fracture line over the edge of a table and bend the overhang slightly downwards. That s the ideal anyway but the reality is that many parts arrive at the press brake in a less than ideal state. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition.

Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. Choose a bend radius that matches your minimum bend. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Bending is one of the most common sheet metal fabrication operations.

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. Bending is always going to be delicate and demanding on any material yet is required for numerous fabricating processes. If you re bending 0 020 thick material use a 0 020 radius. Mark your bend lines.

This weakens the aluminium and creates a fracture line. Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal. Determine your minimum bend by measuring the distance from your closest feature i e. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Different alloys and as we add to pure aluminum however it gets stronger and less pliable. Pure aluminum is rather soft and ductile contrary to what many consumers may think. This is done through the application of force on a workpiece.

We provide a range of metal processing services including tube and steel bending for los angeles california and surrounding areas.
