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.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America.
