Its done with a fame or torch, you heat the copper to a almost cherry red glow, (caution, you don't want it red, if it just starts to glow, "stop" that where you just annealed copper.
but the more you shape it after your annealing process it will harden up again, not due to cooling but due to your shaping it

∙ 14y agoWiki's annswer to the question of HOW to anneal copper is totally wrong and backwards. You anneal copper by heating it with propane torch to dull cherry red, then quinching it in water. (the opposite of annealing ferrous metal)
The purpose of annealing copper is to make it soft again.
One purpose is to soften copper spark plug washers on aircraft engines.

Copper and other pure, unalloyed metals don't harden by quenching, but from cold working. Heating and the quenching rapidly is how you anneal (soften) copper in preparation for cold working. Hammering on a piece of copper so as to stretch the metal will harden it.

∙ 13y agoAnnealing involves heating a metal, and controlling the rate at which it cools, to reduce the hardness of the metal. The exact process will depend on the size and alloy of brass. In reloading brass cartridge cases for firearms, they can become "work hardened" from having been run through the reloading dies several times. We anneal only the necks of those cases by standing them in a pan of water, and heating the case mouth with a torch, then tipping them over into the water.

I really hope this helped

∙ 13y agoCopper goes harder as it ages, which is impractical if you're going to work it. Heating it reverses this process and makes it soft and malleable again.

∙ 12y agoIt is copper that has been heated to make is malleable again. When copper is bent and hammered it becomes hard. To get it back into its original flexible state it has to be heated.

What grade of copper tube is the best suited to being bent using an external bending spring?
orange/red tubing is requried to bend itCopper has a bendable grade see see the CDA drawn and annealed called HARD and soft copper
What is expansion of CRCA?
Cold Rolled Cold Annealed
What is the tensile strength of silver?
Tensile strength annealed 207
What are the properties of CRCA sheet?
cold rolled close annealed -CRCA
What is the compressive strength of aluminum?
That will depend on how it is heat treated and the material type. For example 6061 T6 has an ultimate of 42,000 psi but 6061 annealed is only 18,000 psi. Aluminum 7075 is 80,000 psi heat treated to T6 temper and 33,000 psi annealed.
How do you bend copper pipes?
Depends if the copper tubing is annealed or drawn type as not all copper tubing if bendable
Recrystallization temperature of copper master alloy?
The recrystallization temperature for cop- per usually ranges from 200°C to 400°C.Highly purified copper will recrystallize at 100°C if annealed for a long time.
How do you use anneal in a sentence?
Here is a sentence that uses the word annealed. The various parts are annealed after passing through different machines.
What has the author Brian John Duggan written?

What grade of copper tube is the best suited to being bent using an external bending spring?
orange/red tubing is requried to bend itCopper has a bendable grade see see the CDA drawn and annealed called HARD and soft copper
What is the mineral copper often used to make electrical wires?
Image result for What is the mineral copper often used to make electrical wires? Because of its superior conductivity, annealed copper became the international standard to which all other electrical conductors are compared. The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper .
How well does bronze conduct electricity?
It is a moderately good conductor, but not great. If you rate pure copper at 100%, then regular annealed copper wire rates an 85%, various aluminum alloys are between 50 an 60%, commercial annealed bronze rates a 44%, brass about 32%, and zinc about 29%. There are several different alloys of bronze, by the way, including phosphor bronze. Each has a different conductivity, so the above is rule-of-thumb info, not exact.
