Gunmetal is a type of bronze alloy composed of copper, tin, and zinc, known for its strength, corrosion resistance, and machinability. Traditionally used in the manufacturing of cannons, it has now found applications in making pipes, valves, gears, and bearings due to its durability and resistance to seawater and steam. Gunmetal’s smooth finish and high resistance to wear make it ideal for heavy-duty and marine environments. Its unique composition provides a balance of toughness and hardness, ensuring long-lasting performance.
