I am trying to fabricate a 90deg bend on a .5" thick sheet metal (Gage 3/0). What are the allowable bent radii (inside) for the piece?
Is there a table?
Thanks,
-Paul

your bend rad would depend on what the material is.
I am presuming it is Aluminum.
Here are a selection of Rads taken from the Alcoa hand book
These are for .5" thick material.
2024-0 3t-5t
2024t3 6t-9t
6061t6 4t-6t
7075-0 3t-5t
7075t6 7t-12t
These are inside bends T is the thickness of the material.

I do not think there is a link.
Alcoa published a variety of these handbooks titled "The Alcoa Library of Helpful Information on Aluminum"
The one I am quoting from is, "Forming Alcoa Aluminum"
The only link I could find was for a university that had a copy.
