Product Description Copper Clading Aluminum Plate Sheet Transition JointsCopper and aluminum are both good conductors of electricity and materials for making electric conductors. Copper reserves are few, output is less, processing is more difficult and price is higher. Aluminum is the opposite, and in many cases, copper is replaced by aluminum in the power industry. The substitution of aluminum for copper is an important technical measure for the development of the power industry.The oxide film on the aluminum surface is very strong and the electrical resistivity is very high. Mechanical connections between aluminum and copper are unreliable, and explosive welding is needed to reduce resistance and power consumption and accidents between them.The melting points of aluminum and copper are quite different. Aluminum is oxidized strongly at high temperature, which is easy to form intermetallic compounds such as AlCu2. Therefore, fusion welding between copper and aluminum is rather difficult.The melting points of aluminum and copper are quite different. Aluminum is oxidized strongly at high temperature, which is easy to form intermetallic compounds such as AlCu2. Therefore, fusion welding between copper and aluminum is rather difficult.In comparison, explosive welding, with its unique advantages, can play an important role in the production of large area and arbitrary thickness ratio of Copper Clading Aluminum .Characteristics of explosive welding of Copper clading aluminum transition joints:1. the joint has good corrosion resistance, reliable and stable electrical properties.2. the mechanical property and resistance value of the joint are good.3. the joint has good electrical conductivity and is a rare structural material in the electric, electronic and electrochemical industries.Explosively welded Copper Clading Aluminum are usually used to fabricate transition electrical joints in the form of plates, tubes or bars. Explosive welding of Copper Clading Aluminum transition joints is simple and can be used to weld flat, tubular and axisymmetrical parts. These parts have strong working ability.Intermediate compounds of Al 2Cu with transverse cracks were found on the joint surface of Copper Clading Aluminum pipe, Copper as inner tube and Al as outer tube. Compared with the matrix, the hardness of the compound increased obviously. In addition, the strengthening of the substrate after deformation is obvious. The Copper Clading Aluminum pipe is used for the terminals of the high voltage distribution station.One of the greatest advantages of the conductive busbar connector is the small contact resistance of copper and the low cost of aluminum. The explosive method can be permanently combined into a continuous conductor.Copper clading aluminum plate is used as a transition joint in the production line equipment of aluminum alloy profile surface treatment after machining. On this device, the aluminum side is welded with the aluminum conductive beam, and the copper side contacts with the copper copper base. Contact surfaces are cooled by tap water. The contact surface of this structure will not be overheated and arc-drawn, and the conductive performance is stable, which improves the quality of aluminum surface treatment; avoids heating and reduces power consumption; the life of the conductive plate is prolonged, the number of maintenance and replacement is reduced, and the price is low, which is only 1/4 of the same kind of foreign products. Aluminum surface treatment and large electroplating production equipment has a wide range of applications.Base material1050,1060,1070, 3003, 8011Cladding materialT2StandardGBT 32468-2015Thickness0.1--14.5mmWidth≤1200Length≤6000mmCopper coating thickness K % 8~30TemperO, H24, H18
