Absolutely, positively, YES as both are non ferrous metals and there is no possibility of galvanic corrosion or electrolytic action taking place.
Presuming your taking about RED BRASS as opposed to Yellow
No! That will create intergranular corrosion
Yes.
Yes, either by sweating it or with the right fitting on the copper for the brass to screw on. Yes by soldering , brazing, adapters such as Flagg flow TP fittings , Flaire, screwed , Mechanicl joints
Yes, as long as there is a mechanical connection , ie threaded. You cannot glue them to each other.
Brass= 60%copper + 40%zinc. Bronze = 80%copper+20%Tin. The words "brass" and "bronze" are often used interchangeably, but they are very different metals. Both are alloys and both contain a lot of copper - but that is where the similarities end. Comparatively, brass is a very soft metal. For example, it is used for plumbing fixtures because it is easy to work with and easily tooled. Brass is not as hard as bronze. Brass is also prone to corrosion, so most plumbing fixtures are coated with another metal such as chrome to make it more durable. You will find that a brass bell does not sound as pure as a bronze bell. Brass bells have kind of a "clangy" or "brassy" sound to them. Bronze on the other hand is very hard and can last forever. In fact, there are several grades of bronze. A type called admiralty bronze was used for cannons and is used for propellers on boats.
just cause it dont ok
because it just does, ok? just recycle copper
No, Qwest pipe and joints are OK with well water
Yes, why not.
yeah
only if engrish is ok
i guess y dont u trie it it might work
