Bending Aluminum Sheet With Heat

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

Bending aluminum sheet with heat. Heat it up to 1000 f let it soak at that temperature for about an hour then water quench it. Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical. Lift the clamp bar away from the rear of the brake frame and slide the sheet in perpendicularly to the direction you want to bend it. Insert your aluminum sheet into the brake beneath the removable clamp bar.

Then place the clamp bar back down on top of the aluminum crosswise. Make sure the bar is seated firmly inside the frame. These are small little cracks that are forming on the surface of the material. Typically pure aluminum is more easily worked than the alloys.

Nothing complicated here just heat it up till it s red if it s ferrous and bend it. If you bend aluminum cold and without annealing it you ll probably see that the stretched side turns kinda white. In the event that you are bending a thick piece of sheet metal you can apply heat from a blowtorch along the seam of your bend line to facilitate your bend. Depending on designation alloys go through different heat treatment procedures during production.

To create these precipitates the aluminum is heated using a solution treatment at high temperatures and at a prescribed time then quenched for rapid cooling. It s usually not a big deal but under some conditions this might be a problem. Try to re heat treat any annealed parts before machining if possible. Keep in mind that many kinds of fabricated metal have extremely high melting points and applying your torch injudiciously could cause damage or do harm to your sheet metal or equipment.

Flip the sheet over and repeat. This weakens the aluminium and creates a fracture line.
