Copper alloy material

Abstract

The invention discloses a copper alloy material. The copper alloy material is prepared from the following components in percentage by weight: 2.1 to 2.5 percent of nickel, 0.2 to 0.3 percent of silicon, 0.06 to 0.07 percent of lanthanide series rare earth metal, and the balance of copper and inevitable impurities. The copper alloy material disclosed by the invention has the beneficial effects that the lanthanide series rare earth metal is added into the copper alloy material, so that the conductivity of a copper alloy can be effectively improved, as the conductivities of nickel, silicon and the like in the alloy are lower than the conductivity of copper; and after materials such as nickel and silicon are added, the current-carrying capacity of a wire with a smaller diameter is reduced, but after the lanthanide series rare earth metal is added, the conductivity of the copper alloy is improved even exceeds the conductivity of copper, so that the reduction of the wire diameter can be realized.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a copper alloy material used as a wire. Background technique [0002] At present, the wires used in daily life, 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. A wire in which the conductor is covered with an insulator such as vinyl chloride or glued vinyl chloride in concentric circles. [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 w...

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
