Raw materials of the alloy material for the wiring harness terminal comprise 0.02%-0.07% of Cr, 0.01%-0.2% of Mg, 0.01%-0.2% of Ti, 0.02%-0.3% of Zn, 0.02%-0.3% of Fe, 0.02%-0.3% of Sn and the balance Cu and other inevitable impurities. According to the high-strength abrasion-resistant alloy material for the wiring harness terminal and the preparation method of the high-strength abrasion-resistant alloy material for the wiring harness terminal, after various components of the alloy material for preparing the wiring harness terminal are subjected to smelting, hot rolling, annealing and cooling treatment, the obtained alloy material for the wiring harness terminal is high in strength and hardness, the preparation method is simple, and raw materials are easy to obtain.

Description

technical field [0001] The invention relates to the technical field of alloy preparation, in particular to an alloy material for a high-strength wear-resistant wire harness terminal and a preparation method thereof. Background technique [0002] Pure copper wire has excellent electrical conductivity, corrosion resistance and process performance, and can be widely used in wires for electrical equipment, communication cables, electromagnetic wires and high-fidelity wires. However, with the progress of society, pure copper wires are less and less able to meet the needs of industrial development due to their low strength and the strengthening effect is easy to disappear when heated. Therefore, there is an urgent need for a new type of high-strength wear-resistant copper wire to replace the current pure copper wire. Contents of the invention [0003] The invention aims to provide a high-strength and wear-resistant alloy material for a wire harness terminal, and the material of...
