Beginners guide to copper

Copper is one of the oldest metals used by humans and is a foundational element in our technological and industrial development. A soft, malleable and ductile metal, copper has very high thermal and electrical conductivity and is a component of many metal alloys.

Characteristics of copper

Electrical conductivity

Copper is famous for its exceptional electrical conductivity, which makes it the metal of choice for electrical wiring and components. More than half of copper production worldwide is used in electrical applications. Copper’s ability to efficiently carry electrical current with minimal resistance helps prevent energy loss and ensures reliable power transmission. This is why copper is found in everything from household wiring and power lines to complex electronic devices like smartphones and computers.

Thermal conductivity

Copper also has exceptional thermal conductivity, which means it can transfer heat quickly and efficiently. Ideal for use in heat exchangers, radiators, and cooling systems, copper is commonly used in air conditioning units, refrigeration systems, and car radiators. Its ability to dissipate heat also makes it a key material in electronics, where it helps prevent overheating of sensitive components like microchips. This custom external computer water-cooling system built by Edcon Steel customer Matthew Pearson is a perfect example of copper’s usefulness in electronics.

Malleability and Ductility

Highly malleable and ductile, copper can be easily shaped, bent, and stretched without breaking. This makes it a useful material in manufacturing, as it can be formed into a variety of shapes, from thin wires to complex tubing. Copper’s malleability allows it to be hammered into thin sheets, while its ductility means it can be drawn into fine wires, which is especially useful in electrical and telecommunications industries. Edcon customer, Jonathon Zalakos, used copper for this very reason when creating his exquisite copper sake set.

Corrosion Resistance

One of copper’s most valuable characteristics is its natural resistance to corrosion. When exposed to the elements, copper forms a protective layer of copper oxide that prevents further degradation. Over time, this layer turns green (a patina), which not only adds to its aesthetic appeal but also enhances its durability in outdoor and marine environments. This corrosion resistance makes copper an ideal material for plumbing, roofing, and outdoor sculptures, where exposure to moisture and air is inevitable.

Copper applications

Copper is widely used in various industries for its sought-after characteristics and aesthetic appeal.
