Bending laws of aluminum plates of various thickness
- Jun 04, 2018 -

Recently, I often encountered customers when buying aluminum plate, they would ask questions about aluminum material bending, such as what is the coefficient when 3mm aluminum plate bending? What knives should I use? ; What is the bending coefficient of 5mm thick aluminum plate? Why can aluminium plate crack when bending?

Actually aluminum plate bending coefficient is regular, generally is 0.8 times the thickness of aluminum plate, such as 3 mm aluminium plate bending coefficient is 2.4, 5 mm aluminum plate bending coefficient is 4. Use the knife knife is commonly used in for beautiful, with a straight blade knife pressure is too great, aluminum plate is easy to crack.

Causes of cracking when aluminum plate is bent 180 degrees:

1. The bending side is parallel to the rolling direction of aluminum plate, which is easy to crack and turns the bending direction 90 degrees.

2, 180 - degree bend Angle is too much, more than the minimum bending radius, general bending radius for the thickness of 1.5 times. 3, the cause of the material, others are aluminum alloy, good tenacity not pure aluminum aluminum plate, easy to crack.

4. The thickness of the plate is too thick, and the bending 180 degrees exceeds the bending limit of the material.
