Copper

Pros

Copper is primarily known for two properties: electrical conductivity and thermal conductivity. Compared to other metals, copper has the best electrical conductivity, making it the material of choice for numerous applications such as power cables or electrical components. Thanks to its excellent thermal conductivity, copper is also well suited to products such as heat exchangers and cooling systems. Another advantage and difference compared to other metals is the high corrosion resistance that copper already has by nature. As a result, copper is used not only in the electrical industry but also in the construction industry, especially for products that come into contact with water, such as pipelines or roofing.

Cons

Due to the difficulty of extracting copper and the increasing demand for copper, the price of the metal has risen in recent years. Copper is therefore often more expensive than metals such as aluminum, but its conductivity makes it indispensable for many electronic products. In addition, copper can be susceptible to corrosion in certain aggressive environments, such as salt water. The so-called "patina", a greenish thin layer on the surface of the metal, indicates progressive corrosion. Finally, it is important to note that copper only retains its excellent properties if it is free from impurities. With recycled copper, special care must therefore be taken to ensure that the copper remains pure.
