You clean both surfaces to be joined with a circular steel brush, then heat and 'tin' each piece, with the larger piece being second. When the larger piece is tinned and still warm, insert the small piece into it and seal the rim by running solder all round it..

Brass is an alloy of copper and zinc and the same soldering procedure can be used to solder each.

As long as the base metal is cleaned of oxide and properly fluxed there should be no problem soldering

Answer You have a couple of options. Easiest is to use a special zinc based solder called Alutite, or its close cousin Durafix.

Try a net search for either 'Alutite or 'Durafix' to learn more.

Gas welding is possible too, but you need a special tip/torch to keep oxygen out of the melted zone.

Answer You can't solder aluminum. You heli arc it which is like arc welding steel. Special welder just for aluminum.

You don't. Normal solder will not adhere to aluminum.

Brasses and bronzes can be welded by most common processes. There are so many alloys in these materials that one must be careful in the selection of filler materials.

What are the pros and cons of aluminum radiator equipment?

Aluminum radiator equipment is more efficient for cooling, it is also cheaper and lighter than copper and brass types. Aluminum is easily recycled, whereas brass radiators are more difficult due to the solder used. Aluminum may corrode a little faster than other types, but many coolants are being made now that are more compatible with aluminum radiators. Aluminum is also a bit more difficult to repair than other types of metals that are used in radiators.
