Hardware Class Red Copper Generally Has What Classification

No difference.

Copper, also known as red copper is copper elemental, because of its color for purplish red named. See copper for various properties. Red copper is industrial pure copper, its melting point is 1083℃, no isomeric transformation, the relative density of 8.9, five times that of magnesium. The same volume of mass 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 is named for its purplish red color. It is not necessarily pure copper, and sometimes a small amount of deoxidation elements or other elements are added to improve the material and properties, so it is also classified as copper alloy. According to the composition, Chinese red copper processing materials can be divided into four categories: ordinary red copper (T1, T2, T3, T4), anaerobic copper (TU1, TU2 and high purity, vacuum anaerobic copper), deoxidized copper (TUP, TUMn), special copper with a small amount of alloying elements (arsenic copper, copper tellurium, silver copper). Copper conductivity and thermal conductivity second only to silver, widely used in the production of conductive and thermal equipment. Copper has good corrosion resistance in atmosphere, seawater, some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and many organic acids (acetic acid, citric acid).

Commonly used copper alloys are divided into brass, bronze and white copper.

Pure copper is purplish red metal, commonly known as "red copper", "red copper" or "red copper".
