Bronze is a mixture of copper and tin, but there are several formulas for it.

Most of the products made from bronze today are cymbals for drummers, and every cymbal company makes their bronze differently. You can tell the percentage of tin in a cymbal by looking at the number on the metal. Expensive cymbals are made from bell bronze, which is 20 percent tin, or B20. Bell bronze has more tin in it than will bond chemically to the copper, so there are free tin molecules dispersed throughout the metal. These cymbals are made by casting the metal into a mold, then turning it on a lathe and hammering it by hand to finish the instrument. There is also a "malleable bronze" that contains 8 percent tin, or B8. This metal can be rolled into sheets and stamped on a hydraulic press, which makes the cymbal less expensive to make and to buy. In addition to copper and tin, some cymbals contain silver or gold. These metals change the sound of the cymbal, creating a pitch that appeals to different players.

Answer 2

Bronze is an alloy, which is a mixture of two or more elements, typically metals. In the case of bronze, it is primarily composed of copper and tin.
