I'm interested in building a custom aluminium radiator for a little project I'm planning but I haven't worked with aluminium too much so I have a quick question. The design is going to be fairly straight forward with tubes and fins but I need to know how to 'soldier' the fins. Is there something anyone can recommend? I was hoping to just get some quick solder but wasn't sure what to use.
I would ideally like to anodize it a specific colour afterwards so does this mean it has to be welded with ali?
Thanks :)
