It is undoubtedly an alloy, but I rather doubt it's aluminium.

I've looked again at the pictures and is almost certainly steel as the wall of the tube is too thin to be aluminium.

Reckon you're right Sid, after a bit of searching on google, it does seem to suggest its steel.

At the risk of interrupting some seriously studious google fu I would suggest a magnet might clear up any confusion.

Where's the fun in that?

Personally I'd try arc welding it with a 3.2mm rod, if it blows to pieces, it was too thin

I can't see your pics (my browser), but just a thought.

Since it's not a major structural part, if there is any straight then you could possibly have a plug made to bridge the pieces and loctite and pin them. High strength Loctite (retainer/bearing fit) will not come apart if clean and the proper clearance is used (0.05mm typically diameter), and a through pin will give peace of mind rather than additional security.

The join could be hidden with an outer sleeve similarly fixed.

I would take this into an engineering firm who specialise in fabrication and welding, and get them to do it.
It'll be done right then. Yes, it may cost you £100 but they'll do a structurally sound job, and a neat one too.
I'm sure they'll also have the necessary tools/equipment to make sure the right materials are used for the job as well.

Not saying you're entirely wrong but fabrication and welding is a massive subject rather than something you specialise in.

Strip some stuff out of the way, get a bit of pipe, cut out damaged section, fair it into the frame and join them up.

Grinder and a MIG set.

It is a simple repair that any competent welder should be capable of. It is the sort of thing I used to give an apprentice a pack of cigs to do as a 10 minute foreigner. I wouldn't DIY it though. A bodge would look awful
