sheet metal bending aluminium
sheet metal bending aluminium
(OP)
i'm an amateur maker meddling with diy electronics etc. i've been wanting to make my own cases and i'm thinking about using aluminum sheet metals for that purpose.
google searches leads me to things like bending allowance and K values
https://fractory.com/sheet-metal-bending/
https://en.wikipedia.org/wiki/Bending_(metalworkin...
however, bending allowance and K values say nothing about the minimum internal bending radius smaller than which the material/metal/sheet would simply break rather than simply yield and bend
lets assume that i prefer to use aluminum sheets (i'm not sure about grade but lets say grade 300x, on the notion of the most common)
some of those bending tables i stumbled into with google searches includes
https://www.nalco.co.nz/sites/default/files/NALCO%...
https://www.ullrich-aluminium.co.nz/rolled/rpbend3...
lets say i prefer to use 0.8mm - 1mm sheets (31 mils - 39 mils)
base on the tables found above, i'm getting 0 (zero) or none (blank not specified) for those sheets 0.8mm - 1mm
now my question is:
do 0 (zero) or none (blank not specified) for 0.8mm - 1mm thickness aluminium sheets means that there is no minimim bending radius I can simply hem it without leaving any radius.
or do 0 (zero) or none (blank not specified) means that 0.8 - 1mm aluminium sheets cannot be bent?
thanks much in advance !
p.s. i won't be using a sheet metal brake, i'm using the most primitive tools of them all, possibly angle bars and a mallet / hammer

RE: sheet metal bending aluminium
Google around for home made bending jigs, because you'll want an even evolution of the force throughout the bending process. I can't see that happening using hammers.

They've got a lot of sheet metal forming tools, you might look through their webpage and see if they have something you can use.

Seems a prime example of buy being better than make.
Or reuse re-purpose trash.
If you insist, then making your own break for 1 mm aluminum isn't a bad project in itself. Plywood would be good enough.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
