  3. 3. High Thermal and Electrical ConductivityHigh Thermal and Electrical Conductivity Copper is characterised by its high thermal and electricalCopper is characterised by its high thermal and electrical conductivity – silver is the only other pure metal to have aconductivity – silver is the only other pure metal to have a higher electrical conductivity at room temperature. This ishigher electrical conductivity at room temperature. This is because copper has a single valence electron that is free tobecause copper has a single valence electron that is free to move with little resistance, thereby facilitating themove with little resistance, thereby facilitating the conduction of electricity. Such properties make copper theconduction of electricity. Such properties make copper the metal of choice for use in electrical wiring, circuit boards andmetal of choice for use in electrical wiring, circuit boards and heat sinks.heat sinks.

A copper bar 4 inches thick can be heated, rolled,wire. A copper bar 4 inches thick can be heated, rolled, then drawn into a wire thinner than a human hair! Thisthen drawn into a wire thinner than a human hair! This makes it ideal for making electrical wires. Furthermore,makes it ideal for making electrical wires. Furthermore, copper is easily obtainable and a cheaper resourcecopper is easily obtainable and a cheaper resource compared to silver, despite its electrical conductivity.compared to silver, despite its electrical conductivity.
  5. 5. MalleabilitMalleabilit yy Malleability, or the ability to bend or be hammered intoMalleability, or the ability to bend or be hammered into other shapes without breaking, is another characteristic ofother shapes without breaking, is another characteristic of copper. Pure copper is very soft and malleable, as thecopper. Pure copper is very soft and malleable, as the covalent bonds in copper are relatively weak. Copper’scovalent bonds in copper are relatively weak. Copper’s malleability is the key reason why it is highly versatile andmalleability is the key reason why it is highly versatile and ideal for various applications – for example, in makingideal for various applications – for example, in making copper sheets, coins and utensils.copper sheets, coins and utensils.
