Brass is a metal composed primarily of copper and zinc. Copper is the main component, and brass is usually classified as a copper alloy. The color of brass varies from a dark reddish brown to a light silvery yellow depending on the amount of zinc present; the more zinc, the lighter the color. Brass is stronger and harder than copper, but not as strong or hard as steel.
The alloy we call brass is made up of copper and zinc. The proportions vary as the type of brass we wish to make. The ratio of copper to zinc can be 2:1 or 3:1 or can vary from there. Use the link below to check facts and learn more about the different brass alloys we use.
