Hello All: Neat ng here with all the questions and answers on metal
working.

I have a project coming up where I have to bend some 6061 T6 .18"
thick plate. The bend radius can be 1/2 inch, or even larger.


The minimum bend radius for 6061 T6 is 2 to 4 times the thickness.
The chart on the link is only good for steel! For best results on a
small radius polish the edges of the material at the bend site. 1/2"
looks about right.

I have a file on http://groups.msn.com/IndustrialArts...documents.msnw
with the full range of aluminium alloys and tempers showing the
minimum bend radius for each.
