Problems solved by technology

From the perspective of saving energy, reduce the diameter of wire conductors to reduce weight and save materials. However, the current carrying capacity of wire conductors in the past is fixed, and reducing the diameter of wires also reduces the reduction in passing capacity.
And the reduction in the diameter of the wire conductor leads to a decrease in the folding resistance, so the existing wires can no longer meet these requirements

Embodiment Construction

[0011] The present invention will be described in detail below through specific examples.

[0012] In the present invention, each component is measured by weight percentage.

[0013] The addition of nickel and silicon is an element to improve the strength of the copper alloy. The strength of the copper alloy is improved by forming silicon-nickel precipitates in the copper alloy through nickel and silicon. The weight percentage of nickel is 1.5-3.5%, and the weight percentage of silicon The content is 0.4-0.6%. Although these two elements can enhance the strength of copper alloys, the electrical conductivity of these two elements is much lower than that of copper. Too much addition will affect the electrical conductivity of copper alloys, increase the resistance of copper alloys, and reduce the conduction capacity. .

[0014] Add lanthanide rare earth metals in this technical solution, the rare earth metals can change the crystal arrangement inside the copper alloy, improve t...

Abstract

The invention relates to a copper alloy material. The copper alloy material comprises the following components in weight percentage: 1.5 to 3.5% of nickel; 0.1 to 0.3% of lithium; 0.03 to 0.08% tellurium; 0.4 to 0.6% of silicon; and 0.001 to 0.05% of lanthanide-series rare earth metal. The copper alloy material further comprises copper and inevitable impurities. The copper alloy material has high tensile strength and excellent bending resistance; and the electric conductivity of the copper alloy material is similar to that of copper.

Description

technical field [0001] The invention belongs to the field of alloy materials, in particular to a copper alloy material. Background technique [0002] The wires currently used, especially the wires and cables used in moving or vibrating places, mainly use annealed copper wires or twisted wires formed by twisting copper wires plated with tin, etc. as conductors. The conductors are covered with Wires with concentric insulators such as vinyl chloride or glued vinyl chloride. [0003] Recently, the requirements for the durability, folding resistance and electrical conductivity of wires have become higher and higher. From the perspective of saving energy, reduce the diameter of wire conductors to reduce weight and save materials, but the current carrying capacity of wire conductors in the past is fixed, and reducing the diameter of wires also reduces the reduction of passing capacity. Moreover, the reduction of the diameter of the wire conductor leads to a decrease in the foldin...
