* Copper is a pure metal that has a reddish-brown color. It is soft, malleable, and ductile, and it conducts heat and electricity well.
* Bronze is an alloy of copper and tin. The amount of tin in bronze can vary, but it is typically between 5% and 20%. Bronze is harder and stronger than copper, but it is also less ductile and conductive.
Here is a table summarizing the key differences between copper and bronze:
| Property | Copper | Bronze |
|---|---|---|
| Composition | Pure copper | Copper and tin alloy |
| Color | Reddish-brown | Yellowish-brown |
| Hardness | Soft | Hard |
| Strength | Weak | Strong |
| Ductility | Ductile | Less ductile |
| Conductivity | Conducts heat and electricity well | Conducts heat and electricity less well |
Copper is used in a wide variety of applications, including electrical wiring, plumbing, and jewelry. Bronze is also used in a variety of applications, but it is more commonly used in structural applications, such as bridges and buildings.
