Copper and its alloys have been around for centuries. Brass is an alloy made from copper and zinc, which is why it can be difficult to distinguish copper from brass. Luckily there are a few ways to tell which metal you have.
Instructions
Step 1 Compare your item to a known copper item. Set the two items beside each other and compare the color and the sound, looking for any difference.
Step 2
Look at the color, which is the main way to tell the difference between brass and copper. Copper is a reddish brown metal that turns green when it corrodes, as evident by the Statue of Liberty. The color of brass varies based on the percentage of copper and zinc. Zinc causes the yellow tint most commonly associated with brass, which is why more zinc used in making the brass causes more yellow tones in the brass.
Step 3
Listen to the sound and pitch. If an item is hollow, you can test the metal by thumping it and listening to the sound. If you're trying to tell if an instrument is brass or copper, play it. Copper is a softer metal and creates a mellower, rounder sound. Brass has a brighter or slightly higher pitched sound.
Step 4
Have your item chemically analyzed. There are a variety of ways that a chemist can distinguish copper from brass. You need to make sure that you have a professional analyze it to prevent damage to the metal.
Step 5
Search for markings on the metal. Brass in the United States is regulated by The Unified Numbering System. Brass items are identified by a code starting with C followed by three to five digits. If you see a code like this, it's most likely brass. (end of answer)
One way to test if a metal is copper or brass is to perform a visual inspection. Copper has a reddish-brown color, while brass is more yellow in appearance. You can also use a magnet, as brass is not magnetic but copper is. Additionally, you can conduct a chemical test by applying dilute hydrochloric acid to a small area on the metal. If it bubbles and turns green, it is likely copper; if it turns blue, it is likely brass.
Brass has light shiny finish Bronze has darker finish Copper has a brown rustic finish
Easy copper is just a bit lighter then bronze. so you should look at the color of it
Copper and zinc together create brass, a metal alloy known for its yellowish color and resistance to corrosion. Brass is commonly used in plumbing fixtures, musical instruments, and decorative items.
Copper has a higher electrical conductivity (58 MS/m) compared to brass (15-28 MS/m) due to its atomic structure and crystal lattice arrangement. This difference makes copper a preferred choice for electrical wiring and conducting electricity efficiently. Conductivity can be tested experimentally using a simple conductivity tester to measure the resistance of copper and brass wires.
It is an alloy of copper and zinc, therefore it is a mixture, since a compound is chemically formed while an alloy is just a dissolving of one metal in another. See the link below for more explanation.
The order of expansion rate from lowest to highest is: copper, brass, iron, aluminium. Copper and brass have relatively low thermal expansion coefficients, while aluminium and iron have higher coefficients.
Its caused by the oxidization due to the massive amounts of green plants grown in the Emerald Triangle. The sheer potency of these plants gives off a green hue that attaches itself to bronze (and copper) through reverse osmosis. The 'green' that you see is actually black mold and it is highly advised that you either clean it immediately or take it to a sanitation facility. Hope this helps.

Brass is an alloy of copper and zinc. Common brass or rivet brass is 63% copper and 37% zinc, and that's probably most of the brass we see. But there are a whole bunch of different alloys out there. Use the link to the Wikipedia article on brass to see a list of some of them and find out more about this versatile alloy.
Copper. Mixed with tin, it becomes bronze, and mixed with zinc, brass. You can see this for yourself by taking a shiny U.S. penny from 1984 or newer. Hold it in a flame (even a candle will do) and wait for a color change. Modern pennies are zinc with a little copper, so when heated, it becomes brass.

You can use a magnet to test if something is metal. If the magnet sticks to the object, it is likely made of metal. Another way is to check for properties like conductivity or density, which can also indicate if something is metal.
