Description

Technical Field

[0001] The invention relates to the technical field of casting and rolling, and in particular to a copper-aluminum composite material casting and rolling forming device and a copper-aluminum composite material. Background Art

[0002] Copper-aluminum composite material is a new type of composite material with broad application prospects. Copper-aluminum composite material combines the advantages of copper and aluminum, has good electrical and thermal conductivity, is relatively light and has low cost. For example, copper has high electrical conductivity and thermal conductivity, but is relatively expensive and has a large density; aluminum is light and corrosion-resistant, and the combination of the two can play a unique advantage in many fields; and the interface characteristics of copper-aluminum composite materials have an important influence on their performance. During the preparation process, a composite interface layer composed of intermetallic compounds and eutectic phases will be formed, among which the thickness of the interface layer is an important factor in determining the bonding strength. By adjusting the process parameters, the temperature field distribution in the copper-aluminum composite plate during the solidification process can be optimized, thereby controlling the formation process of the composite interface layer;
