Brass rod is a rod-shaped object made of an alloy of copper and zinc. It is named after its yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, gun shells, etc.

Different zinc content will also have different colors. For example, if the zinc content is 18%-20%, it will be red-yellow, while if the zinc content is 20%-30%, it will be brown-yellow. In addition, brass has a unique sound when struck, so Eastern instruments such as gongs, cymbals, bells, and horns, as well as Western brass instruments are all made of brass.
