What are the commercially sold ones made from?

I try to spec them these days as they are much lighter but costly as you have seen

Why would it rot through?
My aluminium shower cubicle is still very much in one piece after 10 years of daily use.

Yes easier to fit and man handle.
Fitter couldn't work out how to measure for the four separate brackets.
Are all trades full of idiots?

In theory it shouldn't be a corrosive environment, most of the sludge in heating systems comes from the steel radiators breaking down, aluminium heat exchangers usually have a high silicone content, I always thought that was to make them easier to cast though?

Yes, they are all different but it's usually just a bit of measuring

Most of the drive components in marine applications are aluminium. eg jet ski jet pumps, engine ect. These are subjected to heat, saltwater ect.

All in the presence of oxygen.
Aluminium is highly resistant against salt water corrosion.

It's the presence of oxygen that gives aluminium its corrosion resistance. Oxygen reacts with the aluminium and creates an oxide layer.

Interesting about ally rads presume plumbed in with plastic not copper ? now nothing about plumbing, alloy & salt water done a few Volvo outdrives over the years never found one that came apart without a struggle

Same as Corten steel, the Angel of the North is Corten, it gives it the unmistakable colour. A surface layer oxidises and then becomes the protective coating.
If you look at any galvanic series table, Aluminium should corrode sacrificially to Iron....in practice it doesnt because the Oxide forms on the Aluminium surface and protects the Aluminium. I think that the presence of Iron in the water can interfere with the Oxidation process and reduce its effectiveness but Im not sure how severe this is....I suspect, not very, because otherwise we would be hearing of the issues.
Ive read that Aluminium Radiators are greener because they heat up quicker....does that really use less fuel....I should expect the difference between steel and Aluminium "heating up" times to be small and would equalise when cooling down...????
