摘要
PURPOSE: A high strength alloy having new performance is provided in which some of principle alloy elements of Ni and Sn are reduced while elements having functions capable of supplementing material strength and controlling fine structure are added accordingly, and a method for manufacturing the Cu-Ni-Sn alloy is provided. CONSTITUTION: In a copper alloy for high strength wire rods and plates, the Cu-Ni-Mn-Sn-Al, Si-Ce, La, Nd and Pr based alloy comprises 1.0 to 10.0 wt.% of Ni, 0.1 to 10.0 wt.% of Mn, 0.1 to 10.0 wt.% of Sn, 0.1 to 5.0 wt.% of one or more elements selected from the group consisting of Al and Si, 0.01 to 1.0 wt.% of one or more elements selected from the group consisting of Ce, La, Nd and Pr, and a balance of Cu. The method for manufacturing the Cu-Ni-Mn-Sn-Al, Si-Ce, La, Nd and Pr based alloy for high strength wire rods and plates comprises the steps of weighing alloy elements; fusing the alloy elements by continuously injecting and agitating the elements well after the weighing step; manufacturing an ingot by continuously casting or die casting the sufficiently fused alloy elements into plates or rods; performing solution treatment on the manufactured ingot; and aging the solution treated rods or plates.
