Abstract
The invention relates to a copper rare earth alloy material, which comprises the following ingredients in percentage by weight: 1.5-3.5% of nickel, 0.4-0.6% of silicon, 0.001-0.05% of lanthanide series rare earth metal and the balance of copper and inevitable impurities. The copper alloy material has the advantages of high tensile strength, good anti-bending performance and similar electrical conductivity with the metal copper.
Description
Technical field
The invention belongs to field of alloy material, refer to especially a kind of Cu-RE alloys material.
Background technology
The wire that now uses, in particular for wire that mobile or vibrations place are arranged and cable etc., main what use is the twisting thread as conductor of annealed copper wire or the stranded formation of copper cash that is coated with tin etc. on it, is coated with the electric wire of the isolators such as the vinylchlorid of concentric circles or glue connection vinylchlorid on this conductor.
Recently also more and more higher to the requirement of weather resistance, folding resistance and the conductivity of wire.From saving the angle of the energy, reduce the diameter of wire conductor with weight reduction and saving material, but the powered-on capacity of wire conductor in the past is certain, reduces the diameter of wire and has also just reduced reducing by capacity.And the reducing of wire conductor diameter causes folding quality to descend, and therefore existing electric wire can't satisfy these requirements.
Summary of the invention
The purpose of this invention is to provide the improvement of a Cu alloy material, can improve intensity and the specific conductivity of copper alloy by this technical scheme, when guaranteeing powered-on capacity, also guarantee or improve folding quality.
The present invention is achieved by the following technical solutions:
A kind of Cu alloy material, the composition composition of described Cu alloy material includes by weight percentage: the nickel of 1.5-3.5%, the silicon of 0.4-0.6%, the lanthanide rare metal of 0.001-0.05%, all the other are copper and inevitable impurity.
Described nickel, it is 0.1-0.5 μ m particle that silicon and lanthanide rare metal consist of diameter, with 185-205/mm
2Density exists.
The composition composition of described Cu alloy material further includes by weight percentage: the tin of 0.1-0.6%, the cobalt of 0.05-1.0%, the phosphorus of 0.01-0.05%, one or more combinations in the iron of 0.05-0.1%.
Described nickel, it is 0.1-0.5 μ m particle that silicon and lanthanide rare metal consist of diameter, constituting diameter with in described tin, cobalt, phosphorus or the iron one or more is 0.1-0.5 μ m particle, with 185-205/mm
2Density exists.
The composition composition of described Cu alloy material further includes by weight percentage: one or both combinations in the manganese of 0.02-0.1% and the magnesium of 0.08-0.2%.
It is 0.1-0.5 μ m particle that described nickel, one or more in silicon and the same tin of lanthanide rare metal, cobalt, phosphorus or the iron constitute diameter, and constituting diameter with in described manganese or the magnesium one or both is 0.1-0.5 μ m particle, with 185-205/mm
2Density exists.
The invention has the beneficial effects as follows;
By in technical scheme of the present invention, adding the lanthanide rare metal, specific conductivity that can the Effective Raise copper alloy, because the perveance of nickel and silicon etc. is lower than the perveance of copper in alloy, powered-on capacity after adding the materials such as nickel and silicon reduces, but after adding the lanthanide rare metal, the specific conductivity of copper alloy improves even surpasses the specific conductivity of copper on the contrary.
Embodiment
Below come by specific embodiment that the present invention is described in detail.
Each composition is all measured by weight percentage in the present invention.
The adding of nickel and silicon is for the element of the intensity that improves copper alloy, in copper alloy, form the intensity that the tantnickel precipitate improves copper alloy by nickel and silicon, the weight percent content of nickel is 1.5-3.5%, the weight percentage of silicon is 0.4-0.6%, described nickel, it is 0.1-0.5 μ m particle that silicon and lanthanide rare metal consist of diameter, with 185-205/mm
2Density exists.Although these two kinds of elements can strengthen the intensity of copper alloy, the specific conductivity that the specific conductivity of these two kinds of elements is lower than copper is a lot, and the amount of adding too much can affect the specific conductivity of copper alloy, increases the resistance of copper alloy, and powered-on capacity descends.
In the technical program, add the lanthanide rare metal, this rare earth metal can change the crystal arrangement of copper alloy inside, the percent of pass that improves electronics can improve the powered-on capacity of copper alloy, and the consumption of the lanthanide rare metal that is suitable among the present invention is 0.001-0.05%.Certainly can increase the consumption of lanthanide rare metal, but increase the cost that too much improves on the contrary copper alloy according to the purposes of wire, and when usage quantity surpasses 1.0%, can not increase again on the contrary the electric conductivity of copper alloy.
For Cu alloy material of the present invention, can also contain at least a in tin, iron, cobalt, the phosphorus, phosphorus can increase the intensity of Cu alloy material in these elements, but consumption too much can affect the toughness of Cu alloy material.Improve the bending endurance quality when other several elements can increase Cu alloy material intensity, concrete consumption is the tin of 0.1-0.6%, the cobalt of 0.05-1.0%, the phosphorus of 0.01-0.05%, the iron of 0.05-0.1%; Described nickel, it is 0.1-0.5 μ m particle that silicon and lanthanide rare metal consist of diameter, constituting diameter with in described tin, cobalt, phosphorus or the iron one or more is 0.1-0.5 μ m particle, with 185-205/mm
2Density exists.When the consumption of these elements is too much, can affect the specific conductivity of Cu alloy material.
Can also select at least a in two kinds of elements of magnesium and manganese among the present invention, these two kinds of elements can preventing adding thermal embrittlement and improve very large advantage is arranged aspect the hot workability, be conducive to reduce diameter of wire.But can obviously affect the conductivity of copper alloy when the consumption of these two kinds of elements surpasses 0.5%, the consumption of these two kinds of elements is the manganese of 0.02-0.1% and/or the magnesium of 0.08-0.2% in the present invention.It is 0.1-0.5 μ m particle that described nickel, one or more in silicon and the same tin of lanthanide rare metal, cobalt, phosphorus or the iron constitute diameter, and constituting diameter with in described manganese or the magnesium one or both is 0.1-0.5 μ m particle, with 185-205/mm
