What is the general classification of red copper

There's no difference.

Red copper, also known as red copper, is copper, because of its color for purplish red. See copper for various properties. Copper is industrial pure copper, its melting point is 1083℃, no isotropic transition, the relative density of 8.9, five times that of magnesium. The mass of the same volume is about 15% heavier than that of ordinary steel. Because of its rose red, the surface of the formation of oxide film is purple, it is generally called copper. It is copper containing a certain amount of oxygen, so it is also called oxygenated copper.

Copper is named for its purplish red color. It is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the material and performance, so it is also classified as copper alloy. Chinese copper processing materials can be divided into four categories according to composition: ordinary copper (T1, T2, T3, T4), oxygen free copper (TU1, TU2 and high purity, vacuum oxygen free copper), deoxidized copper (TUP, TUMn), special copper with a small amount of alloying elements (arsenic copper, tellurium copper, silver copper). The electrical and thermal conductivity of red copper is second only to silver, and it is widely used to make conductive and thermal conductive equipment. Copper has good corrosion resistance in atmosphere, sea water and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid).

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

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