Problems solved by technology

At this time, if the temperature of precision rolling (final rolling) is too low (for example, below 500°C), there will be such a problem: during rolling, the cracks of the rolled material will increase, so the appearance quality of rough drawing will be extremely sharp. fall, and with it, the strength of the tram line drops sharply
Therefore, precipitation-strengthened alloys have

Abstract

The present invention provides a copper alloy material having high strength and a high electric conductivity, to provide a method of manufacturing a copper alloy conductor using the same, to provide a copper alloy conductor obtained by the method, and to provide a cable or a trolley wire using the copper alloy conductor. The method of manufacturing a copper alloy conductor 18 comprises the steps of: (F1) adding and dissolving In 12 of 0.1 to 0.7 weight% to a copper matrix 11 containing oxygen of 0.001 to 0.1 weight% (10 to 1,000 weight ppm) to form a molten copper alloy 14, (F2) performing a continuous casting with the molten copper alloy 14, rapidly quenching a casting material 15 to a temperature by at least 15[deg.]C or more lower than a melting point of the molten copper alloy 14, controlling the casting material 15 at a temperature equal to or lower than 900[deg.]C, and (F3) performing a plurality of hot rolling processes to the casting material 15 such that a temperature of a final hot rolling is within a range of from 500 to 600[deg.]C to form the rolled material 16.

Description

technical field [0001] The present invention relates to a copper alloy conductor for a tram line (supply wire for a tram) for supplying power to a tram through a pantograph, or a copper alloy material with high conductivity and high strength constituting a copper alloy conductor for a cable used in machines and the like, and A method of manufacturing copper alloy conductors using these conductors and materials. Background technique [0002] Copper alloy conductors for electric train wires (supply lines for electric trains) and copper alloy conductors for cables used in equipment, etc., use hard copper wires with high electrical conductivity or copper alloy materials with wear resistance and heat resistance (copper alloy wire). As a copper alloy material, a copper alloy material containing 0.25 to 0.35% by weight of Sn in a copper base material (see Japanese Patent Publication No. Sho 59-43332) is known to be wired as a power supply line for electric trains of Shinkansen and...
