Abstract

The invention discloses a cold-rolled copper and aluminum composite material production process. The process includes using an aluminum strip as a base strip and a copper strip as a strip covering material, performing surface treatment, performing composite rolling prior to heat treatment at the temperature of 605-610 DEG C, keeping the temperature for 8-10min, and finally forcedly cooling to the normal temperature by water cooling, wherein the thickness of the copper strip is 18-22% of that of the aluminum strip, the surface roughness of the aluminum strip satisfies that Rz=95-115 micrometers, and the surface roughness of the copper strip satisfies that Rz=80-95 micrometers. Optimum matching of deformation, layer thickness ratio and composite strength can be realized, and the process has the advantages of high interface composite strength and good dynamic thermal stability.

Description

technical field [0001] The invention relates to a production process of cold-rolled copper-aluminum composite material. Background technique [0002] At present, the commonly used conductive materials in the electric power industry are copper and aluminum. At the same time, they are also commonly used heat exchange materials in the world. The instantaneous heat absorption capacity of copper is 1.61.6 times faster than that of aluminum, but the heat dissipation speed is relatively slow. The heat dissipation speed of aluminum 2.33 times that of copper block. But it is also easy to oxidize in an environment higher than room temperature, especially in an environment containing corrosive gases. Therefore, under the harsh conditions of industrial and mining, aluminum bars are reused instead of copper bars. If the two metal materials are combined, it will be a perfect conductive and heat exchange material. Therefore, copper-aluminum composite materials are an excellent choice fo...
