Copper is a transitional element, while pure copper is a soft metal with a reddish orange color and metallic luster when the surface is first cut. Good ductility, high thermal conductivity and conductivity, therefore, they are the most commonly used materials in cables, electrical and electronic components, and can also be used as building materials to form various alloys. Copper alloys have excellent mechanical properties and low electrical resistivity, with bronze and brass being the most important ones. In addition, copper is also a durable metal that can be recycled multiple times without compromising its mechanical properties
