Concept Métal, your supplier of pure copper
Pure copper is the benchmark metal for electrical and thermal conductivity. Used for thousands of years, it remains indispensable today in electronics, energy, heat exchangers, and numerous industrial applications.
What is pure copper?
Pure copper (symbol Cu, atomic number 29) is an orange-red metal with a copper content of more than 99.9%. It is available in several grades, depending on its degree of purity and oxygen content.
This metal has many advantages:
- the best electrical conductivity after silver
- excellent thermal conductivity
- good resistance to atmospheric corrosion
- high ductility and ease of forming
The most common grades are Cu-ETP (electrolytic), Cu-OF (oxygen-free), and Cu-OFE (high-purity for electronics).

The Properties of Pure Copper
Electrical Conductivity
Pure copper offers benchmark electrical conductivity (100% IACS). This property makes it indispensable for the manufacture of cables, busbars, electrical contacts, and power components.
Thermal Conductivity
With a thermal conductivity of 401 W/m·K, pure copper is the ideal material for heat exchangers, radiators, heat sinks, and injection molds.
Ductility
Pure copper can be easily shaped by deep drawing, bending, wire drawing, and machining. This property facilitates the manufacture of complex parts and precision components.
What are the industrial applications for pure copper?
Due to its conductivity and ductility, pure copper is used in many industries for the manufacture of:
- bus bars and electrical contacts
- heat exchangers and radiators
- power electronics components
- anodes and cathodes for surface treatments
- waveguides and microwave components
- welding electrode
