[0005] Copperalloy materials with isotropic orientation should have high strength, high electrical conductivity, heat resistance, etc., and require high comprehensive performance. At present, beryllium-containing alloys are mainly used in China. Copperalloy, but berylliumcopper alloy contains beryllium, cobalt and other elements, which makes the production cost of the material very high, and the high beryllium element will cause environmental pollution and personal harm in the alloy production process
Both at home and abroad are looking for substitute materials for beryllium bronze alloys. CuNi2SiCr, CuNi9Sn3 and other series of copper alloys have been developed successively. Some performance indicators of these materials have reached the level of beryllium bronze, but there is still a big gap in the overall performance indicators. How to improve the beryllium bronze substitute The comprehensive performance of materials is still a topic to be further studied in the field of copper alloys

Abstract
The invention discloses a high temperature resistant superconductive copper wire which is prepared by the following components comprising, by weight, 80-200 parts of copper, 30-80 parts of aluminum, 5-20 parts of cupric oxide, 1-5 parts of nickel, 10-15 parts of chromic oxide, 5-10 parts of magnesium, 1-10 parts of iron trioxide, 1-6 parts of manganese, and 2-10 parts of silver. The high temperature resistant superconductive copper wire provided by the invention has extremely high conductivity, and is safe and harmless; a preparation method of the copper wire is very simple, and the copper wire is especially suitable for large-scale production.
Description
technical field [0001] The invention relates to a metalalloy, in particular to a high-temperature-resistant superconducting copper wire and a preparation method thereof. Background technique [0002] A large amount of high-conductivity copper is consumed in power transmission and is mainly used for power applications. Wire and cable, bus bars, transformers, switches, plug-in components and connectors, etc. During the power transmission process of wires and cables, electric energy is wasted due to resistance heating. From the point of view of energy saving and economy, the standard of "best cable section" is being promoted in the world at present. The popular standards in the past simply started from the perspective of reducing an installation investment, in order to minimize the cable cross-section, so as to avoid dangerous overheating under the rated current required by the design, to determine the minimum allowable size of the cable. Although the installation cost of c...
