Radiator top and bottom tanks - aluminium?

I have a pinhole leak on the upper radiator. Looks like the ends are aluminium - is this correct?
Will take it to a repair place on monday to get it soldered up and hopefully the rest is not too rotten to last a few more years.

Gooday Downunder,
have just seen your post, did you get it fixed OK?
The ends on all of mine seem to be a copper looking metal pressing.

Hi GP,
It was aluminium and I had it fixed by a radiator shop - no leaks and holding pressure so all good.

Excellent! Happy riding
