Abstract

The invention discloses an aluminum substrate layer material of a copper-aluminum composite metal strip, a strip and a machining method of the strip. According to the invention, the aluminum substrate layer material of the copper-aluminum composite metal strip is formed by adding the elements of Si, Fe, Cu, Mn and Ti into an aluminum substrate layer material, so that the machining property of an aluminum substrate layer is improved effectively, the machinability of the aluminum substrate layer can accord with that of a copper covering layer. According to the invention, a copper covering layer material with the shop sign of TU2 and the state of TM is adopted by the copper-aluminum composite metal strip as the copper covering layer, so that the machining property of the aluminum substrate layer can further accord with that of the copper covering layer. The strip adopts multi-pass rolling, reduces single-pass machining rate, and adopts sectional type annealing, so that the reliability of annealing is improved, and the abnormality of copper and aluminum caused by the difference of properties is restrained. The copper-aluminum composite metal strip manufactured through the machining method has the advantages that the bonding strength is high, and the strip cannot easily crack because of bend.

Description

technical field [0001] The invention relates to an aluminum matrix layer material of a copper-aluminum composite metal strip, and also relates to the metal strip and a processing method thereof, belonging to the field of material processing. Background technique [0002] my country's copper resources are scarce, most of which depend on imports, and copper resources are expensive, so the research on the effective and rational use of copper resources has become a top priority. The research and development of copper-aluminum composite metal strips provides a new direction for the effective and economical utilization of copper resources. Copper-aluminum composite metal strips are formed by continuous casting of aluminum strips and copper strips. The finished products are beautiful, durable, and have good processing performance. It reduces the consumption of copper resources and can replace copper strips for decoration, so it has a good promotion prospect. However, copper-alumin...
