Red copper tube is rose red metal, density value 8.96g/cm, specific gravity value 8.89g/mm, thermal conductivity of 386.4W /(M.K) resistivity (20℃) 0.018 ω ·mm2/m, hardness value ≥ 85.2HV. According to hardness, it is divided into O state, 1/4 hard, 1/2 half hard, full hard and extra hard. Product parameters: Product status: M (soft), Y2 (1/2 hard), Y (hard), T (extra hard) and other states.

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). Copper pipe is widely used in chemical industry, sanitary ware, refrigeration, electric power, auto parts, instruments, steam turbines, lamps, welding and cutting tools, connectors, heat exchangers, pens, rivets, fishing gear, Musical Instruments, precision parts and other aspects.
