Brass is any alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses, each of which has unique properties. Note that in comparison bronze is principally an alloy of copper and tin. Despite this distinction, some types of brasses are called bronzes. Brass is a substitutional alloy. It is mainly used for decoration, plumbing and electrical applications, and extensively in musical instruments.
Brass types
Admiralty brass contains 30% zinc and 1% tin which inhibits dezincification in most environments.
Alpha brasses (Prince's metal), with less than 35% zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar. They contain only one phase, with face-centered cubic crystal structure.
Alpha-beta brass (Muntz metal), also called duplex brass, is 35-45 % zinc and is suited for hot working. It contains both α and β' phase; the β'-phase is body-centered cubic and is harder and stronger than α. Alpha-beta brasses are usually worked hot.
Aluminum brass contains aluminum, which improves its corrosion resistance.
Arsenical brass contains an addition of arsenic and frequently aluminium and is used for boiler fireboxes.
Beta brasses, with 45-50 % zinc content, can only be worked hot, and are harder, stronger, and suitable for casting.
Cartridge brass is a 30% zinc brass with good cold working properties.
Common brass, or rivet brass, is a 37% zinc brass, cheap and standard for cold working.
DZR brass is Dezincification resistant Brass with a small percentage of Arsenic.
High brass, contains 65% copper and 35% zinc, has a high tensile strength and is used for springs, screws, rivets.
Leaded brass is an alpha-beta brass with an addition of lead. It has excellent machinability.
Low brass is a copper-zinc alloy containing 20% zinc with a light golden color, excellent ductility and is used for flexible metal hoses and metal bellows.
Naval brass, similar to admiralty brass, is a 40% zinc brass and 1% tin.
Red brass, while not technically brass, is an American term for CuZnSn alloy known as gunmetal.
White brass contains more than 50 % zinc and is too brittle for general use.
Yellow brass is an American term for 33% zinc brass.
Gilding Metal is the softest type of brass commonly available. It is an alloy of 95% copper and 5% zinc and is typically used for ammunition components.

Well, I am a chemist.
Brass is any alloy made up of copper and zinc. It consists of two elements, copper and zinc. Hope this helps.

No.
It is a mixture of copper and tin or zinc. Mixed metals are known as alloys. Most metals are made into alloys. Copper is the metal which is used the most in its pure state, usually in electrical wires. Chromium is also used a lot as a pure element in the form of chrome plate. Iron is always used as an alloy, and gold is as well.

No it's an alloy - a mixture of the elements copper and zinc

Nope it's an alloy of copper and zinc. That's why the development of bronze weapons and tools was such an advancement. It took time to figure out the smelting process

No, it's a combination of copper and zinc, therefore an alloy/homogeneous mixture.
