What kind of brass in what form? The density of the aluminum also matters, so it could scratch if both materials were slightly thick. The aluminum would have to be a little flimsier than the brass.
becasue the alluminum is denser than the copper.
It cost more energy, time, money and produces more negative effects to the environment to recycle than to make items from scratch. Aluminum is the only useful recycling.
Manganese, aluminum, silicon, phosphorous, steel and brass make up a very small portion of alloys. For a more complete list, refer to the "related links".

Aluminum can scratch zinc, but zinc cannot scratch aluminum.
yes
Most basically, brass is an alloy of copper and zinc, while aluminum is a pure element.
no
You can tell if your coat hooks are made of brass by doing a little test. Get a magnet and put it near the coat hook, if it is pulled to the magnet, then it is not real brass also if you scratch it, and it leaves a silver mark then they are not brass, but in fact brass plated. If however you scratch it and it looks kind of yellowish, then it might be brass.
The advantage to brass over aluminum is the wear and oxidation rates. Not really the conduction when new
each is a metal
Brass is reloadable, whereas aluminum is not. Also, brass is a softer metal than aluminum, which allows both for a better seal in the chamber, and puts less wear on the extractor.
on some vehicles yes aluminum will scratch easily so if you need to be sure scratch it with a screwdriiver it will mark if it's aluminum, cast iron will not mark You can also check it with a magnet. The magnet won't stick to aluminum but it will stick to steel.
Brass is an alloy of copper and zinc.
An alloy of copper and zinc is called brass. Tin or aluminum can be added to brass to increase its resistance to corrosion. (see related link for types of brass)
