Metal in Bronze is an alloy composed of copper and TIN. It is a strong and durable material that has been used for centuries in the production of tools, weapons, and other objects. TIN is one of the main components of bronze, making up about 10-20% of its composition. TIN is a soft, malleable metal that is resistant to corrosion and oxidation. It is also a good conductor of electricity and heat. The combination of copper and TIN creates a strong and durable material that is ideal for many applications.
