I'm guessing a zinc alloy, but is it good?

If it melts with propane, it almost certainly is zinc based. I've used
the hardware store variety and it's useful, but not nearly as good as
they say (surprise). This stuff is certainly not $65 a lb (+ shipping)
good (I paid $16ish). It's best use is filling stripped/wallowed out
holes for re-drilling (& tapping). It's weakest use is under tension.
What sort of stress will your cubes be subjected to?

Pretty much what I thought. Thanks everyone.
Looking it up to post a link. This version says it has stainless steel
corners.

Makes sense. I was wondering how the Al would hold up to use.
You can see by the price why we'd rather make a couple.
Thanks

Find a TIG welding shop that will make the corner blocks for you, or
cut and fit, and silver solder the parts yourself.

The rest of the cube is overpriced tubing.

Work out the attachemnt by whatever means you prefer.

I can silver solder. Now that I've come across the secret of the
corners It should be possible to make it with tools on hand. Just got
to find reasonably priced Al tube.
Thanks
Karl .

See what you can find for Titanium tubing.

There are a lot of Ti. tubes used in the aircraft industry as
hydraulic and fuel lines, and you may be able to source some out that
have lost their certs. Compared to aluminum, Ti. tube is noticably
lighter, and very stiff.

I hadn't thought of that. I assumed it was out of our price range.
Thanks
