As when air forming any other material, when forming aluminum, you choose an appropriate die width based on the material thickness and the radius-to-thickness relationship… See more

In my 40-plus years in the trade I have bent quite a lot of 6061-T6 aluminum. I’ve avoided cracking by having a large radius relative to the material thickness. And I’ve sometimes … See more

Let’s consider a challenging job. Say you’re bending 0.25-in.-thick 6061-T6 aluminum to a 100-degree external angle (80-degree internal angle). To make this easier, you’d start with y… See more
