(LIFE SAFETY WARNING! [disclaimer]
Electricity is dangerous!
You can be injured or killed!
Improper installations can cause fire, injury and death!
1] Combinations of aluminum and copper conductors require precise procedures and materials for proper termination at a splice.
2] All conductors are required by the NEC to terminate in a suitable enclosure whose volume has been determined on the basis of the size, type and number of conductors entering the enclosure, the entry fittings, installed devices, etc. <><><> Copper and aluminum exposed to the air will react and the resulting corrosion will form a very bad, high resistance, connection that will get hot and could start a house fire when high current flows through it. To avoid this risk you need to use special connectors which have been designed to connect aluminum wire to copper wire. <><><> You must use an approved Anti-Oxidant Compound such as "Noalox", or connectors "listed" for that purpose. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work
AND
always use an electricians test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.

use duck tape it works on everything : D i have to agree, adhere it if you can, otherwise use a VERY low heat propane torch. Acetylene burns WAY too hot, and you won't get a good arc going over 2 types of metal. Also, I don't know if you can find a compatible filler rod though. If you do get the metals to stick together, becareful, if wont be very strong. Good luck The proper way to join aluminium pipe to copper is to use a threaded adaptor on the aluminium and add a copper adaptor . you then solder the copper.
Copper sulfate (CuSO4) is not a binary compound of copper and sulfur but a compound of copper, sulfur, and oxygen. It can be made by electrolysis of copper with sulfuric acid: Cu + H2SO4 --> CuSO4 + H2
Scrap iron can be used to displace copper from solution through a redox reaction. Iron has a higher reactivity than copper, so when the scrap iron is added to a solution containing copper ions, the iron will oxidize and donate electrons to the copper ions, causing the copper to be reduced and precipitate out of the solution as solid copper.
Thermite welding is a process that uses a chemical reaction to create intense heat to join two pieces of metal together. It involves a mixture of aluminum powder and metal oxide that, when ignited, produces temperatures high enough to melt the metal. This method is commonly used to join railroad tracks and other large metal structures.
Because if you join copper (the pipe) directly into steel (the radiator) the electrolytic difference is so great they would corrode very quickly. By using brass between them you reove this risk.
That is called a 'junction'
A junction. I live in a place called Grand Junction where three rivers merge.
To allow the metal elements copper and aluminum to interact - thus allowing electrolysis to take place - the metals must not be dry: they must be in contact with an electrically-conducting fluid which is called an electrolyte.Even the moisture in damp air can act as an electrolyte, so, unless the metals are very closely and well-bonded together mechanically, such as by welding, electrolysis will occur if such metals are just in close contact and are unprotected from the atmosphere.Such electrolysis is called corrosion.
Junction 6 was reserved for the M273 motorway to join the M27, however it was never built (I dont know why not).
Petticoat Junction - 1963 Mind If We Join Your Wedding 5-7 was released on: USA: 21 October 1967
I have recently had to join a 1 inch steel water pipe to a new copper 28mm pipe. You can do this using a 28mm comression joint. 1inch is just uneder 28mm in diameter but the compression joint takes up the difference and works without fault or leaks.
Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.

Yes, quite easily

The root "junct" comes from the Latin word "jungere," which means "to join" or "to connect." This root is commonly used in English words related to joining or connecting, such as "conjunction" or "junction."
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
