Provide solutions of new copper-aluminum composite conductor
materials for global customers
Since the positive electrode fluid set of lithium battery must be aluminum and the negative electrode is copper, the connection between copper and aluminum must beinvolvedin the series pressure boostin the module. Because welding must be used to ensure electrical conductivity, the use of copper aluminum composites can greatly reduce the difficulty of copper aluminum connection.
Large mechanical and electrical equipment, such as wind turbine, has numerous conductive components and wires. Among them are aluminum and copper. lf copper and aluminum are directly connected mechanically, it is easy to cause the electrochemical corrosion of aluminum to affect the life of the equipment. Such problems can be avoided by using copper-aluminum composites.
In order to reduce the cost of materials they will use relatively cheap aluminum foil rather than copper foil when the conductive demand is not high. But the fatal problem with aluminum is the difficulty of tin welding.The copper and aluminum composite materials in Shanghai should shake have a high binding force(~100MPa) which can meet the welding strength required by the electronic components. The welding performance and strength are consistent with the copper material, but the cost is lower.
Cu/AlSemi-Molten Rolling Composite Process (Solid-Liquid Composite) Through continuous casting and rolling composite process, according to equipment control and process adjustment, using aluminum ingots and copper strips as raw materials, copper and aluminum in the composite process have reached a semi-molten state, achieving 100% metallurgical composite of copper and aluminum. The process is carried out under high temperature, high pressure, and oxygen-free conditions, solving the problem of copper and aluminum oxidation during the copper-aluminum composite process.
This meets the composite temperature and precise time requirements for heat penetration between the two metals, controlling the formation and expansion of the eutectic layer, resulting in high copper-aluminum composite strength.
