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)
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
Test it with the circuit and see which one lights up the bulb fastest.
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)

Brass is an alloy of copper and zinc. The proportions vary a bit as the alloy desired. Use the link below to check out the Wikipedia post on the alloy brass and see what's up.
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.

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.
The workmen are brassing the elevator doors to make the metal look shiny and clean .
