1. Excellent electrical conductivity: Copper is an excellent conductor of electricity, second only to silver. This makes it a crucial material in electrical wiring, motors, and electronics.

2. High thermal conductivity: Copper also conducts heat very well. This property makes it useful in heat exchangers, radiators, and cooking utensils.

3. Malleability and ductility: Copper is highly malleable, meaning it can be hammered or pressed into thin sheets. It is also ductile, meaning it can be drawn into wires. This makes it easily shaped for various applications.
