Hi all, do and have all the Land Rovers ( series and 90's / 110's etc ) had
their bodywork made of the alloy or is it just ally these days. Can you buy
sheets of Bermabright from sheet metal stockists

Probably not as "Birmabright" (tm), but isn't it just an
aluminium-magnesium alloy ? That makes it a 5000 series alloy.

So if Birmabright is a trade mark, what is the correct type of material that
Land Rover still use?

I think AL 5059 is pretty close, if not identical, but I am not a
metallurgist.
Technically, Birmabright is Cu. 1.0 Mn. 1.5 Mg. 1.0 to 6.0 Si. 0.7 Ni.
..5 Cr. 0.5 - try matweb for its composition database. Its definitely a
"5000" series alloy (the ones containing Mg)

Whatever it's called, the ali used by LR is no longer anything
like Birmabright, sadly. The currrent (post 110 introduction) alloy
is nothing like as robust, you dent a Defender wing by leaning on it,
never mind standing on it.

Is it just thinner, or have they changed alloy since they are deep
forming it more ?

A mates got a 54 plate 90, the alloy is half as thick as my 1984 110 i reckon. If not, it bloody feels
it!
