Abstract

The present invention relates to a conductive material for high-power motor and a production method thereof. The material contains such chemical components as 0.10-0.9% of cadmium, 0.02-0.30% of zirconium, 0.10-0.30% of silver, 0.10-0.50% of zinc, 0.10-0.20% of titanium, and 0.02-0.05% of phosphorus, and not greater than 0.005% of impurities, and not greater than 3 ppm of oxygen, wherein the sum of the zirconium, silver, zinc, titanium, and phosphorus is not greater than 1%. The material in the present invention has the characteristics of high strength, high electrical conductivity, and the like.The softening temperature of the material is higher than 550 DEG C. At 360 DEG C, the material has the tensile strength of greater than 400 MPa and the elongation of greater than 15%, thus meeting the requirements of use for a high-power motor.

Description

technical field [0001] The invention relates to a conductive material and a production method thereof, in particular to a conductive copper alloy material for a high-power motor and a production method thereof. Background technique [0002] High-performance copper alloy is a new type of structural functional material widely used in the fields of electronic information technology, electrical power technology, communication technology, transportation, aerospace, and major national defense equipment. Conductivity is the most important characteristic of copper and copper alloys, which determines the high cost performance of copper and copper alloy materials. Therefore, it has become the most widely used type of metal materials for conductive purposes, among which conductive copper alloy profile products for high-power motors occupy an important position in this type of material, and are widely used in various motors in the transportation industry. In recent years, my country's ...
