1. Product description
High combination rate copper clad aluminum sheet has the respective advantages of copper and aluminum and can be used as a multi-performance composite. Copper aluminum rolled composite material not only has the advantages of copper conductivity, high thermal conductivity, easy brazing, low contact resistance and beautiful appearance but also has the characteristics of light aluminum, corrosion resistance, economy, etc. It is widely used in power, electronics, information, electrical, heat transfer, and other industries. Therefore, our research group has developed a copper aluminum copper three-layer rolling composite technology for the conductive bus bar.
2. Product Features
1) When the width of the high combination rate copper clad aluminum sheet is 60mm, the impedance of the composite plate decreases significantly with the increase of the thickness of the composite plate. The influence of the increase of the thickness of the copper component on the impedance of the composite plate is smaller than the width of the composite plate, and the thickness of the copper component exceeds 0.5mm. The impedance of the composite plate with the same thickness changes little with the copper component.
2) When the thickness of the copper layer is kept at 0.4 mm, the impedance of the composite plate decreases gradually with the increase of the thickness of the composite plate; The influence of width on impedance is less than that of composite plate thickness.

3. Application
High combination rate copper clad aluminum sheet combines the advantages of copper and aluminum single materials and is widely used in metallurgy, automobile, electronic products, and other fields. In practical applications, metal composite plates need to be cut to form specific lengths and shapes. Due to the complex layered structure of copper aluminum composite plates, their shear section morphology and fracture mode are quite different from those of single-layer plates. Therefore, it is of great significance to study the influence of process conditions on the shear quality of copper aluminum composite plates and their fracture mode.
4. FAQ
Metal composite is a kind of material that combines two or more kinds of metals with different properties through a specific process method. Its low price, superior performance, and good structural strength are increasingly recognized by various industries such as electronics, electronics, electric power, metallurgy, machinery, automobile, energy, and daily necessities, and its application fields are increasingly broad.
