What color is copper metal

When the copper surface is just cut, it is red-orange with metallic luster, and the element is purple-red.

Copper salts are the most common copper compounds. Their hydrated ions are usually blue, while the chloride ligands are green. They are the source of the color of minerals such as blue copper ore and turquoise. They have been used extensively throughout history as pigments. Copper building structures are corroded to produce green (alkaline copper carbonate). Decorative arts mainly use copper and copper-containing pigments.

Copper is a non-ferrous metal that is closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China. Copper is a red metal, but also a green metal. It is said to be a green metal mainly because it has a low melting point and is easy to re-melt and re-smelt, so it is quite cheap to recycle. In ancient times, it was mainly used for the casting of utensils, artworks and weapons. The more famous utensils and artworks are the Houmuwu Ding and the Siyang Fangzun.
