Bronze is a durable metal alloy primarily made of copper and tin, often with small amounts of other elements like aluminum or phosphorus. Known for its warm, reddish-brown color and excellent resistance to corrosion and wear, bronze is widely used in bearings, marine fittings, sculptures, and musical instruments. It has good strength and machinability, making it ideal for both artistic and industrial applications. Its low metal-on-metal friction also makes it valuable in mechanical systems.
