what birmabright is.

Shamelessly poached from elsewhere on the net.....


To give it its proper spec. Birmabright BB2, Produced by Birmetals
Ltd., Birmabright works, Clapgate Lane, Quinton, Birmingham. Now
defunct . This material could have also been called Hiduminium 22 ,
Alcan GB M57S , BA 21, Alcoa 510 , AWCO 21 . These being the same
thing, but produced by other companies of that era. But we only know it
as Birmabright, because thats where the factory purchased it from. Today
we know this material as NS4, or in American terms 5251. ISO
designation A1 MG2. .

Best of luck with the welding, I've tried a few times and always cock
it up, never seem to be able to get the amps/feed rate, and the
quality of Birmabright seems to change as you weld, needing
a change in amps/feed rate. I've got some Birma for sale in my
eBay shop if you want some practice bits. After welding it will
need to be annealed otherwise it becomes very brittle, from
memory rubbing some tallow on the surface and waiting for
that to melt is right temperature.

Or if you get really desperate I've got some pretty straight panels
- tub sides, tub rear (lights), wing sides, wing tops, etc.

It's difficult to get right, because it's an aluminum/magnesium alloy.
So you fry it if you get oxygen to it.

The OP did say he was TIGing it.
I find that thin sheet benefits from "backflushing", if you can arrange it.

I welded piece of roof top with a tig (square wave) and it turned out
OK , but I didn't use any filler rod.

thanks for your replies.

I think some of the roof bits may be steel - at least the front bit on my
Disco is rusting like steel does - just over the windscreen.

Yep, that's the pro way to do it. You also need the right stuff to
weld it with. slicing very thin strips off an old, but thoroughly
cleaned up panel works.
