Copper – the red gold
Copper is with a density of 8,9 kg/dm³ a heavy metal although relatively soft and ductile, but even resistant. Due to the extraordinary material properties it is applicable in several areas.
Copper, a versatile material
The most important properties are the excellent conductance of heat and electricity.
The good resistance to corrosion depends on the enthalpy of reaction. The surface first covers with a dark brown to nearly black protective coart and develop step-by-step into a green patina [composite of basic cuprous salt, depending on the concentration of the elements in the air].
Copper and copper alloys achieve considerable variations of mechanical and physical properties by modification of the alloying components.
