Abstract

The invention relates to a production method of a tellurium-selenium copper bar. The tellurium-selenium copper bar comprises the following components of, by mass percent, 0.4-0.7% of tellurium, 0.004-0.012% of phosphorus, 0.1-0.15% of selenium, 0.05-0.1% of sulfur and 0.1-0.15% of antimony, wherein the ratio of the selenium content to the antimony content is 1:1. In addition, the tellurium-selenium copper bar comprises any two elements of silver, titanium, cerium, boron, cobalt, chromium, nickel, niobium and the like, and the content of each of the two arbitrary elements is 0.001-0.005%. The tensile strength of the prepared tellurium-selenium copper bar is greater than 300MPa, the elongation percentage is greater than 15%, and the electric conductivity is greater than 88% IACS.

Description

technical field [0001] The invention relates to a production method of nonferrous metal materials, in particular to a production method of tellurium selenide copper rods. Background technique [0002] Tellurium copper is a copper alloy grade in the American standard, also known as phosphorus deoxidized tellurium-containing copper. The alloy contains 0.4-0.7% of tellurium, 0.004-0.012% of phosphorus, and the total content of copper, silver and tellurium is greater than 99.9%. Tellurium copper rods are mainly used to make forgings and screw machine products. Typical parts include electrical connectors, automotive parts, switch parts, pipe fittings, solder tips, torch tips, transistor bases and furnace brazed assembled parts. It is a free-cutting copper alloy with 85% machinability of C36000 (free-cutting brass), and is suitable for cold and hot working. [0003] Chinese patent CN200810147883.3 discloses tellurium-copper alloy materials used in the electrical power industry ...
