Description

A kind of Cu-RE alloys

Technical field

The invention belongs to field of alloy material, particularly relate to a kind of Cu-RE alloys.

Background technology

The wire now used, in particular for having mobile or the wire in vibrations place and cable etc., mainly uses Annealed copper wire or be coated with the twisting thread as conductor of the stranded formation of copper cash of stannum etc. on it, this conductor is coated with the chloroethene of concentric circles The electric wire of the insulators such as alkene or glue connection vinyl chloride.

More and more higher to the requirement of durability, folding resistance and the electric conductivity of wire.From the angle saving the energy Setting out, the diameter of reduction wire conductor is to alleviate weight and to save material, but the powered-on capacity of conventional wire conductor is certain , reduce the diameter of wire and it also reduce the reduction by capacity.And the reduction of wire conductor diameter causes under folding quality Fall, the most existing electric wire cannot meet these requirements.

Summary of the invention

It is an object of the invention to provide the improvement of a kind of Cu alloy material, copper alloy can be improved by this technical scheme Intensity and electrical conductivity, also ensure while ensureing powered-on capacity or improve folding quality.

The present invention is achieved by the following technical solutions:

A kind of Cu-RE alloys, the composition composition of described Cu alloy material includes by weight percentage: 1.5-3.5%'s Nickel, the aluminum of 0.1-0.5%, the scandium of 0.01-0.05%, the indium of 0.1-0.3%, the zirconium of 0.01-0.03%, 0.001-0.003% Ruthenium, the silicon of 0.4-0.6%, the lanthanide rare metal of 0.001-0.03%, remaining is copper and inevitable impurity.

Described nickel, silicon and lanthanide rare metal constitute a diameter of 0.1-0.5 μm particle, with 185-205/mm²Density is deposited ?.

The composition composition of described Cu-RE alloys farther includes by weight percentage: the stannum of 0.1-0.6%, 0.05- The cobalt of 1.0%, the phosphorus of 0.01-0.05%, one or more combinations in the ferrum of 0.05-0.1%.

Described nickel, silicon and lanthanide rare metal constitute a diameter of 0.1-0.5 μm particle, with in described stannum, cobalt, phosphorus or ferrum One or more combinations constitute a diameter of 0.1-0.5 μm particle, with 185-205/mm²Density exists.

Described Cu-RE alloys composition composition farther include by weight percentage: the manganese of 0.02-0.1% and One or both combinations in the magnesium of 0.08-0.2%.

One or more combinations in described nickel, silicon and the same stannum of lanthanide rare metal, cobalt, phosphorus or ferrum constitute a diameter of 0.1- 0.5 μm particle, constitutes a diameter of 0.1-0.5 μm particles with one or both combinations in described manganese or magnesium, with 185-205/ mm²Density exists.

The invention has the beneficial effects as follows；

By adding lanthanide rare metal in the inventive solutions, it is possible to be effectively improved the electrical conductivity of copper alloy, Because the electrical conductivity of nickel and silicon etc. is less than the electrical conductivity of copper, the powered-on capacity after adding the material such as nickel and silicon in the alloy Reduce, but after adding lanthanide rare metal, the electrical conductivity of copper alloy improves the electrical conductivity of even more than copper on the contrary.

Detailed description of the invention

Below by way of specific embodiment, the present invention is described in detail.

The most each composition is all measured by the percentage by weight.

The element of the addition of nickel and the silicon intensity in order to improve copper alloy, forms tantnickel in copper alloy by nickel and silicon and analyses Going out thing to improve the intensity of copper alloy, the weight percent content of nickel is 1.5-3.5%, and the weight percentage of silicon is 0.4- 0.6%, described nickel, silicon and lanthanide rare metal constitute a diameter of 0.1-0.5 μm particle, with 185-205/mm²Density exists. Although both elements can strengthen the intensity of copper alloy, but the electrical conductivity of both elements is a lot of less than the electrical conductivity of copper, adds The amount entered too much can affect the electrical conductivity of copper alloy, increases the resistance of copper alloy, and powered-on capacity declines.

By adding the aluminum of 0.1-0.5%, the scandium of 0.01-0.05%, the indium of 0.1-0.3%, 0.01-in the application The zirconium of 0.03%, the ruthenium of 0.001-0.003% can improve frame strength and the electrical conductivity of copper alloy.

Adding lanthanide rare metal in the technical program, this rare earth metal can change the crystal row within copper alloy Row, the percent of pass improving electronics can improve the powered-on capacity of copper alloy, the use of the lanthanide rare metal being suitable in the present invention Amount is 0.001-0.03%.It is of course possible to increase the consumption of lanthanide rare metal, but increase the most on the contrary according to the purposes of wire Improve the cost of copper alloy, and the conductivity of copper alloy will not be further added by when usage amount is more than 1.0% on the contrary.

Copper rare earth alloy material for the present invention, it is also possible to containing at least one in stannum, ferrum, cobalt, phosphorus, these elements Middle phosphorus can increase the intensity of Cu alloy material, but consumption too much can affect the toughness of Cu alloy material.Other several elements Improving bending endurance quality while can increasing Cu alloy material intensity, concrete consumption is the stannum of 0.1-0.6%, 0.05- The cobalt of 1.0%, the phosphorus of 0.01-0.05%, the ferrum of 0.05-0.1%；Described nickel, silicon and lanthanide rare metal constitute a diameter of 0.1-0.5 μm particle, constitutes a diameter of 0.1-0.5 μm particle with one or more combinations in described stannum, cobalt, phosphorus or ferrum, with 185-205/mm²Density exists.The electrical conductivity of Cu alloy material can be affected when the consumption of these elements is too much.

Can also select at least one in magnesium and two kinds of elements of manganese in the present invention, both elements can prevent heating Brittle and improve hot-working character aspect and have the biggest advantage, advantageously reduce diameter of wire.But the consumption of both elements surpasses Can significantly affect the electric conductivity of copper alloy after 0.5% time, the consumption of both elements is 0.02-0.1%'s in the present invention Manganese and/or the magnesium of 0.08-0.2%.One or more combinations in described nickel, silicon and the same stannum of lanthanide rare metal, cobalt, phosphorus or ferrum Constitute a diameter of 0.1-0.5 μm particle, constitute a diameter of 0.1-0.5 μm grain with one or both combinations in described manganese or magnesium Son, with 185-205/mm²Density exists.

Embodiments of the invention 1-6 use high-frequency melting stove each component melts casting copper base, by copper base at 900 DEG C After carrying out hot extrusion, pure fire process obtains pole immediately, and the most cold drawn obtaining expects material.

Composition and performance in each specific embodiment are shown in Table 1

Table 1

By above example, comprising only nickel, the conductivity of the copper alloy of silicon and lanthanide rare metal is the highest close to copper Conductivity, but intensity is the highest.The preferred embodiment of the present invention is 3 and 4.
