What spec aluminium to use?

[aerosam]

Hi Guys,

quick question, what grade aluminium is the right one to use to make the bonnet, rear panel, all flat panels etc?

I know the book says half hard, but is that 1050-H14 or 3103-H14 spec. I spoke to my local stockist and described how I wanted to use it and he told me it would have to be a special grade and would have to get back to me on pricing. It would be nice to ring him up on Monday and tell him exactly what I want.

Thanks!

Sam

I used 2mm 5251 for my floor and 1.2mm 1050A for all my panels. the 1050 Has been fine to work with and folds and bends nice and easily.

hi
is the 1050a half hard or semi hard we use a lot of half hard at work which is very soft.

i used 5251 1.5mm for everything on my car because it happened to be on offer at parkers the week i ordered it. it was a git to bend and shape :D use 1.2mm 1050 for anything that need a bend in it
