Abstract

The invention discloses copper alloy and a manufacturing process thereof. The manufacturing process comprises the following steps of: preparing an intermediate copper alloy block and a rare-earth alloy block; adding the prepared intermediate copper alloy block into refined copper liquid in a tilting refining furnace, and homogenizing copper alloy; and adding the weighed rare-earth alloy block at the initial end of a sealing trough, and smelting to obtain the copper alloy. The copper alloy has the hightensile strength, high wear resistance and high corrosion resistance, has the stable high-temperature performance at high temperature, namely a high-temperature softening initial point is high, and has the high conductive performance.

Description

technical field [0001] The invention relates to a copper alloy and a manufacturing process thereof. Background technique [0002] Copper is used in more occasions to conduct electricity, while copper alloys are more concerned with the comprehensive mechanical and electrical properties. For copper alloy products in terms of shape and wire, more mechanical properties are paid attention to, and sometimes high temperature performance is also considered. For example, high-speed electrified catenary wire products have higher requirements for copper alloys, in addition to higher requirements for strength and wear resistance, and higher requirements for high-temperature softening initiation temperature. Therefore, for the manufacture of a copper alloy, it can not only achieve high mechanical performance index, but also make the electrical performance reach the ideal state (as close as possible to the resistance value of pure copper), and its stability at high temperature is also go...
