Why do people mix metal tin and copper?

Answer 1

We combine pure metals with other metals to create metal alloys. An example of an alloy is steel, which is mainly composed of iron and carbon. This is stronger than pure iron, and is mostly used as a building material.

Answer 2

The mixture of tin and copper is bronze which is useful for its properties: "Bronze can be superior to iron in many applications. It is considerably less brittle than iron. Bronze only oxidizes superficially; once the surface oxidizes, the thin oxide layer protects the underlying metal from further corrosion. Copper-based alloys have lower melting points than steel or iron, and are more readily produced from their constituent metals. They are generally about 10 percent heavier than steel, although alloys using aluminumor silicon may be slightly less dense. Bronzes are softer and weaker than steel, e.g. bronze springs are less stiff (and so store less energy) for the same bulk. Bronze resists corrosion (especially seawater corrosion) and metal fatigue better than steel and also conducts heat and electricity better than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel-base alloys such asstainless steel. Copper and its alloys have a huge variety of uses that reflect their versatile physical, mechanical, and chemical properties. Some common examples are the highelectrical conductivity of pure copper, the excellent deep-drawing qualities of cartridge case brass, the low-friction properties of bearing bronze, the resonant qualities of bell bronze, and the resistance to corrosion by sea waterof several bronze alloys." - http://en.wikipedia.org/wiki/Bronze

Answer 3

People mix metal tin and copper to create an alloy called bronze. Bronze is commonly used in applications where a combination of strength, ductility, and corrosion resistance is needed, such as in sculptures, Musical Instruments, and tools. The addition of tin improves the strength and hardness of the copper, making bronze a versatile material.
