Which Are Bendable Aluminum Sheets

There are many kinds of aluminum sheets which can be bent. The temper of the bendable aluminum sheet is very important. The temper is divided into full hard, semi-hard, and soft temper.

The full hard bending effect is basically not good. The full hard temper includes H18, H19, H38,etc. The semi hard aluminum plate can basically be bent. H24 is a common semi-hard temper. Bending in the O temper is certainly no problem, but it is too soft to be used for bending.

It also has some relationship with the aluminum alloys. The hardness of pure aluminum is not very good. 1100, 1050, 1060, etc. aluminum alloys can be used. We recommend 1100-H26 aluminum sheet for bending.

The hardness of aluminum alloys is better like 3003 aluminum sheet, 3005 and 5052 aluminum sheet. They have good bending performance in the semi-hard temper. 6061, 2024 and 7075 aluminum sheet is two hard, especially in T6 temper. If you like to bend them, you can first heat and then bend.

In addition, for the bending of aluminum sheets, there is a bending coefficient. A simple calculation is aluminum plate thickness*1.6. The aluminum plate has rolling lines. It is best that the bending tool and the rolling line intersect at 90 degrees, which is not easy to crack.
