Copper alloy is a mixture of copper with one or more other metals, enhancing its properties for various applications. Common alloying elements include tin, zinc, and aluminum, which improve strength, corrosion resistance, and conductivity. These alloys are widely used in electrical wiring, plumbing, and decorative items. The most well-known copper alloys are bronze and brass. Bronze, primarily made of copper and tin, is known for its durability and resistance to wear, making it ideal for sculptures and marine applications. Brass, a combination of copper and zinc, is valued for its malleability and acoustic properties, often used in musical instruments and fittings.
