Copper aluminum composite material

Product Introduction

Product size: thickness 3.0~15.0mm, width ≤ 500mm.
Application field: Conductive industry (can be widely used in high and low voltage distribution cabinets, complete sets of switches, bus ducts, electrolytic cells, etc.).

Product features: The copper aluminum composite row produced using our company's multiple patented technologies solves the two major problems of copper aluminum composite, which are easy to oxidize and the oxide film is difficult to eliminate, as well as the formation of intermetallic compounds (AbCu) between copper and aluminum at lower temperatures. After SEM analysis, the thickness of the transition layer between copper and aluminum in traditional copper-clad aluminum bars is 15-50 um, while the thickness of the transition layer between copper and aluminum in our company's copper aluminum composite bars is only 1-2um, which is much lower than that of traditional copper-clad aluminum bars. This not only achieves metallurgical bonding between copper and aluminum, but also effectively ensures the bonding strength between copper and aluminum, solving the problem of high resistivity of the transition layer. Excellent comprehensive performance, with bending, drilling, punching and other properties similar to pure copper. With low density, it can save more than 30% of costs during use.
