The invention discloses a novel rare-earth tellurium-copper alloy material, which comprises the following components in percentage by weight: 0.30%-0.38% of Te, 0.01%-0.02% of Ce, 0.8%-1.0% of Mn, 0.01%-0.5% of Re, 0.1%-1.2% of Ti, 0.6%-2.0% of Co and the balance of Cu, wherein the total mass is 100%. According to the novel rare-earth tellurium-copper alloy material disclosed by the invention, due to addition of cerium-rich mischmetal, the problem of poor high-temperature performance is solved; and the service life of the novel rare-earth tellurium-copper alloy material is obviously prolonged in comparison with a general copper alloy material.
Description
[0001] technical field [0002] The invention relates to an alloy material, in particular to a novel rare earth tellurium copper alloy material. [0003] Background technique [0004] Copper and copper alloys have high thermal conductivity, electrical conductivity, corrosion resistance, and good manufacturing and processing properties, so they are widely used in many fields such as electric power, electrical engineering, machinery, and aerospace. However, with the increasingly stringent requirements of these high-tech materials on material performance, traditional copper alloy materials can no longer meet the application requirements in some fields, especially in the occasions where comprehensive performance such as high strength, high electrical conductivity, oxidation resistance, heat corrosion resistance, etc. are required at the same time, For example, the electrodes and contact materials of various electric welding machines are required to maintain excellent electrical...
