When you anneal copper it expands and becomes soft and pliable thus giving you a seal once the copper has been compressed.
This process refers to the way in which a hot rolled piece of stainless steel sheet or plate is finished after manufacturing.
The metal is heated above its recrystallization temperature maintained at this temperature and then cooled in a controlled environment.
You can anneal any grade and thickness of copper as long as you have a flame that can transmit enough heat to the metal.
Annealing copper makes it softer and less brittle which allows you to bend it without breaking it.
