Yeah, I just save it up and sell the Copper/Ali radiators like that.
I used to cut the tubes out, but it costs a lot of time and some grinder discs, the other option is to use a bandsaw, either beside the tubes, or right thru them, but then you loose Copper and a bit of Ali.
I just use the 9inch angle grinder to cut the loops off each end, normally on the outside of the Steel strip if there is one, then peel the steel strip off with pliers. Its a good quick clean way to do it and maximise the return while putting less time into it.
I did find that if the Ali fins are corroded a bit, when you cut the rad apart, the corrosion falls off, loosing weight and making a real mess, and that Ali metal looks real bad, takes up lots of space.
Together they are cleanish, stack easy and have their own price. I have noticed over the years that the prices for 'Plastic coated Copper wire' and 'Ali/Copper radiators' have risen above their original prices.
I expect this is because there's buyers just for this material and they are maximising their returns too, and can pay more for their specific materials.
Ie, the plastic coating on the wire now gets sold as 'Filling' for cheap leather belts, in China of course. But if they profit off that only, they can pay near return price for the actual Copper.
