What metal is added to copper to create Bronze?

The correct answer, tin, is crucial in the creation of bronze because it combines with copper to enhance the properties of the resulting alloy. Bronze, which is primarily composed of copper, typically consists of about 90% copper and 10% tin. This combination greatly improves the strength, durability, and resistance to corrosion compared to pure copper. Tin also helps to lower the melting point of the metal, making it easier to cast into different shapes.

The use of tin in bronze-making has a long historical significance, as it allowed for the development of stronger tools and weapons, marking a key advancement in metallurgy during the Bronze Age. This innovation facilitated advancements in various fields, such as agriculture, construction, and art, showcasing the importance of tin in enhancing the utility and versatility of copper.
