Which metals are combined to create bronze?

Bronze is an alloy primarily composed of two metals: copper and tin. The process of combining copper and tin creates a material that is harder and more durable than pure copper, making it suitable for a variety of applications such as tools, weapons, and decorative items. This combination takes advantage of the different properties of the two metals, enhancing the overall characteristics of the resulting alloy.

In contrast, the other options consist of different metal combinations that do not produce bronze. For example, iron and carbon form steel, copper and zinc create brass, and silver and gold are often used together in jewelry but do not form bronze. The distinct properties of bronze stemming from its copper and tin composition are what make it historically significant in metalworking and various industries.
