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.
