Product Features
The copper key composite row produced by our company's patented technology solves the two major difficulties of copper key oxidation oxide film that is difficult to eliminate and copper key composite between copper keys that are easy to produce intermetallic compounds (Al2Cu) at lower temperatures
Question, after SEM analysis, the thickness of the transition layer between copper and aluminum in the traditional copper-clad aluminum row is 15~50pm, while the thickness of the transition layer between copper and aluminum between copper and aluminum produced by our company is only 1~2um, which is far lower than the traditional copper-clad aluminum row, that is, the metallurgical combination between copper and aluminum is realized, and the bonding strength between copper and aluminum can be effectively guaranteed, and the problem of high resistivity of the transition layer is solved, and the comprehensive performance is excellent, bending, drilling, punching and other properties are the same as pure copper, and the density is small, and the cost can be saved by more than 30% when used.
Application
1. Power Industry: Copper clad aluminum laminated plate are used to replace traditional copper bars and transformer copper windings, while ensuring the performance, reducing the overall cost and lighter weight.
2. Electronic industry: Copper clad aluminum laminated plate is used instead for heat conduction and heat dissipation system, which can improve thermal conductivity and heat dissipation effect under the original function. It can be used for conductive transition board, high and low voltage distribution cabinet, switch set, bus bar, electrolytic cell and so on.
3. LED industry: The use of copper clad aluminum laminated plate can give full play to the good thermal conductivity of copper and heat dissipation performance of aluminum, reduce the overall thermal resistance of LED packaging, effectively reduce the junction temperature of the chip, and make it possible for higher power LED packaging.
