Abstract

The invention belongs to the manufacturing field of duplex metal composite panel belt, and discloses a method for manufacturing a copper-clad aluminum composite panel belt. The manufacturing method comprises two steps of the preparation of copper-clad and aluminum-clad core casting blank and the manufacture of the copper-clad aluminum composite panel belt. The method has simple processing technique, firm combination of copper-aluminum duplex metals, and low requirements for the carrying capacity of the process equipment, thereby being easy to realize continuous production and automation production, better improving the quality and the production efficiency of the products, reducing the production cost, and meeting the application needs.

Description

Technical field: [0001] The invention belongs to the field of manufacturing bimetallic composite strips, and relates to a method for manufacturing copper-clad aluminum composite strips. Background technique: [0002] The reserves of aluminum in the earth's crust are extremely rich, about 5%, second only to iron, and the market price is relatively low, with good ductility and light specific gravity, while copper resources are relatively scarce, expensive, and have high thermal conductivity , good conductivity, good plasticity, easy processing, and sufficient strength at high temperatures, so aluminum is used instead of copper, and copper-aluminum composite strips are developed instead of copper strips for electrical devices, conductive devices, etc. On the one hand, precious copper can be saved On the other hand, it can retain the superior electrical conductivity and good thermal conductivity of copper, and at the same time have the appearance of copper metal. Copper-aluminum...
