When it comes to bending aluminum, elongation at break is a critical parameter that should not be overlooked. This mechanical property holds the key to the formability and ductility of the material, both of which are indispensable in bending processes.
How to bending aluminum without cracking it
Minimum Thickness: There is a minimum thickness that can be successfully bent without causing defects. Below this threshold, cracking or other forms of material failure may occur.
Minimum Bend Radius: The minimum bend radius is the smallest radius that the aluminum can be bent without causing cracking or excessive deformation. This value depends on the alloy, temper, and thickness of the material.
Different aluminum alloys have distinct properties and characteristics that influence their formability.
The formability of aluminum alloys varies by type, with softer tempers (e.g., O, H12, H14) generally being more formable. To bend aluminum without cracking, choose a formable aluminum alloy (e.g., 3003), opt for a softer temper.
The aluminum alloy is too hard and easy to break. The choice of aluminum alloy profile mainly depends on the grade and condition of the aluminum. Usually, T1, T3, and T5 are used. T6 and T7 series are too hard… Read More »Common 5 Best Aluminum Alloys For Bending And Welding
