Copper-based alloys are materials made primarily of copper mixed with other metals, such as zinc, tin, or aluminum. These combinations enhance the properties of copper, making the alloys stronger, more resistant to corrosion, and suitable for various applications. Common types include brass (copper and zinc) and bronze (copper and tin). These alloys are widely used in industries like construction, electronics, and automotive due to their excellent conductivity and malleability. They can be found in products ranging from electrical wiring to decorative items, showcasing their versatility and importance in modern manufacturing.
