Can you tell me what is the classification of red copper?

Red copper, also known as red copper, few impurities, close to pure copper, toughness, ductility are good; Brass is copper containing a small amount of zinc. Poor toughness, ductility, high hardness; Bronze contains tin, or beryllium, more kinds, wear-resistant. Copper is copper elemental, because its color is purplish red named. Red copper and red copper belong to the same material, namely pure copper copper is copper elemental, because its color is purplish red and named. Red copper and red copper belong to the same material that is pure copper... Copper is copper elemental, because its color is purplish red named. Copper is industrial pure copper, its melting point is 1083℃, no isomerism transformation, the relative density of 8.9, five times of magnesium. The mass of the same volume is about 15% heavier than ordinary steel. Because of its rose red, the surface of the formation of oxide film is purple, so it is generally called red copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper. Copper gets its name from its purplish red color. It is not necessarily pure copper, sometimes a small amount of deoxidation or other elements are added to improve the material and performance, so it is also classified as a copper alloy. Chinese copper processing materials can be divided into four categories according to their composition: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), and special copper with a small amount of alloying elements (arsenic-copper, telluric-copper, silver-copper). Copper is second only to silver in conductivity and thermal conductivity, and is widely used in the production of electrical and thermal conductive equipment. Copper has good corrosion resistance in air, sea water and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid). Red copper has good electrical conductivity and thermal conductivity, plasticity is very good, easy to hot pressing and cold pressure processing, a large number of used for manufacturing wire, cable, brush, electric spark special electrolytic copper and other requirements of good electrical conductivity products.
