Abstract
A high-efficiency and short-process method for preparing a high-strength and high-conductivity copper alloy is disclosed, comprising the following steps: performing horizontal continuous casting to obtain an as-cast primary billet of copper alloy, wherein the alloying elements in the obtained as-cast primary billet being in a supersaturated solid solution state; after peeling the obtained as-cast primary billet, directly performing continuous extrusion, cold working and aging annealing treatment to obtain a copper alloy, and keeping the alloying elements of the billet in a supersaturated solid solution state during the process of continuous extrusion. The method shortens the flow, reduces energy consumption and improves the product forming rate.
