Copper alloys are materials made by combining copper with other metals, such as tin, zinc, or aluminum. These mixtures enhance the properties of copper, making the alloys stronger, more resistant to corrosion, and suitable for various applications. Common types of copper alloys include bronze (copper and tin) and brass (copper and zinc). These alloys are widely used in industries like construction, electronics, and plumbing due to their excellent conductivity and durability. For example, brass is often used for plumbing fittings, while bronze is favored for marine applications because of its resistance to seawater corrosion.
