Brass is commonly used in various applications, including musical instruments, plumbing fittings, and decorative items, due to its durability and workability. The properties of brass can vary depending on the ratio of copper to zinc, which can affect its color and strength. For example, brass instruments like trumpets and trombones benefit from brass's acoustic qualities, while plumbing fixtures utilize its resistance to rust and tarnish. Overall, brass is a versatile material with many practical uses.
