Pure copper is a soft metal, with a metallic luster of red orange color when the surface is just cut, and the single substance is purplish red. It has good ductility, high thermal conductivity and conductivity, so it is the most commonly used material in cables, electrical and electronic components, and it can also be used as a building material, which can form many kinds of alloys. Copper alloy has excellent mechanical properties and low resistivity, among which bronze and brass are the most important. In addition, copper is also a durable metal, which can be recycled many times without damaging its mechanical properties. Divalent copper salt is the most common copper compound. Its hydrated ions are usually blue, while chlorine as ligand is green. It is the source of the colors of minerals such as chalcopyrite and turquoise, and has been widely used as pigments in history. When the copper building structure is corroded, it will produce copper green (basic copper carbonate). Decorative arts mainly use copper and copper containing pigments.
