Method for manufacturing ultrahigh-tension wire with single-crystal alloy material

Abstract

The invention discloses a method for manufacturing an ultrahigh-tension wire with a single-crystal alloy material. The method takes copper as the basis, then adds silver, aluminum, palladium, beryllium, and rare earth. The manufacturing method comprises: extracting high purity copper, then adding silver, aluminum, palladium, beryllium, and rare earth, conducting mechanical mixing and then puttingthe mixture in a high purity graphite crucible for preparing an alloy ingot; adding the well prepared alloy ingot into a single-crystal casting machine so as to be prepared into an as-cast single-crystal busbar with a diameter of 3mm, and pulling the as-cast single-crystal busbar to a sub-roll of at least 14 micrometers, thus achieving the performance requirements of a high-tension wire. The product manufactured by the invention has higher electrical conductivity, higher fatigue resistance, higher tensile strength, and higher bendability. The method of the invention simultaneously improves welding performance, toughness and anticorrosion elements, and enhances the atmospheric antioxidation ability of the material. Thus, the ultrahigh-tension wire product of the invention can be widely used in magnetic head coils, cables for medical equipment, high-voltage cables, high quality speaker wires, miniature vibrating coils and other products needing an ultrahigh tension property.

Description

technical field [0001] The invention relates to an ultra-high tension wire, in particular to a method for manufacturing an ultra-high tension wire from a single crystal alloy material. Background technique [0002] Due to the continuous miniaturization, light weight, high functionality, high-density installation and high temperature of the use environment of electronic products, as well as higher requirements for the thinner diameter and high tensile strength of the micro-magnetic wire, not only require Light weight, small diameter, power increase, and the characteristics that the micro wire is easy to break during the winding process. In order to improve the safety tension and take into account other characteristics, consider the use of copper alloy mixed with other components in the processing material selection to make the safety tension It has been greatly improved, and at the same time, the decrease in conductivity is not too large. This alloy conductor mainly composed...
