Brazing for hobbies
You should use solder, not brazing. Brazing is used to join iron or steel products together.

Brazing is also known as soldering or soft soldering in the layman vernacular.
Yes, brazing can stick to metal by creating a strong bond between the brazing material and the metal surface through the application of heat. Brazing relies on capillary action to securely join two or more metal pieces together.
No, soldering and brazing fluxes are not the same. Soldering fluxes are designed to remove oxides from the metal surfaces being joined during soldering, while brazing fluxes are formulated to clean the joint and promote wetting for the filler metal in brazing processes. Additionally, brazing fluxes can handle higher temperatures compared to soldering fluxes.
You usually do not braze copper, you solder it. If you were to use brazing rod on copper, the copper would have very close to the same melting point as the brazing rod. This makes it difficult to do. As far as preheating the copper, it needs to be hot enough for the brazing to flow.
Flux can be applied using brazing rods. Bronze and Steel weldings can also be applied using brazing rods. You can also apply iron and other types of metal.

Common gases used in brazing include acetylene, propane, natural gas, and hydrogen. These gases are typically used in combination with oxygen to produce a flame with the appropriate temperature for brazing different materials.
You must use flux while brazing because the flux prevents oxides from forming while the metal is heated. The flux also serves the purpose of cleaning any contamination left on the brazing surfaces.
When Brazing copper to copper flux is normally not needed When brazing steel or copper based alloys then the flux is used to help the wetting action (Better flow of the brazing alloy) and to prevent oxidation A typical rod would be Union Carbide 25 M or check out the AWS booklet
