Brass is an alloy of copper and zinc, known for its excellent corrosion resistance, high malleability, and good electrical conductivity. Its attractive golden color makes it a popular choice for decorative applications, such as jewelry and hardware. Additionally, brass is widely used in plumbing fittings, musical instruments, and electrical connectors due to its durability and ease of machining. With varying compositions, brass can be tailored for specific properties, making it a versatile material in various industries.
