Aluminum Angle Rolling

[KVARM]

We are planning to roll an aluminum angle with dimensions 260 mm x 100 mm x 3 mm thick.

The angle will be fabricated from an aluminum sheet of either alloy 5052 or 6061.

We kindly request your expert advice on the following:

1. Alloy Selection: Which alloy (5052 or 6061) is more suitable for rolling to a 4-meter radius? Please consider factors such as formability, springback, and potential for cracking during the rolling process.
2. Material Form: Would you recommend using extruded profiles or sheet metal for this specific application? Please consider factors such as ease of fabrication, and potential for achieving the desired radius.

Thank you for your valuable time and expertise.

I read your post 4 times, it's not clear what you want.
You want to make an angle from sheetmetal?
I'm not sure why you would roll an extrusion to make a radius.

OP may mean extruded sheet.

Either forms fine, depends on your strength requirements.

Yes, bend sheet metal (rolled or extruded no difference).

You're curving this sheet, a 4m radius, rather than "bending" it ... like forming a 90deg bend with a 1/2" rad.

It sounds like they want a ring. Flange in, flange out, vertex in, vertex out; and which flange is the main flange for the radius?

Most of them have a 3-5 x minimum radius; so a 260 mm wide flange could be rolled to a 600 mm radius in the plane of the flange.

5xxx series has better formability than the 6xxx series does, but has generally lower strength; they have differing corrosion resistance.
