Description
Technical field
The invention belongs to field of alloy material, refer to a kind of copper alloy for valve and preparation method especially.
Background technology
The valve now used, in particular for having the valve of mobile or vibrations place and cable etc., mainly use annealed copper wire or it is coated with tin etc. the stranded formation of copper cash twist thread as conductor, this conductor is coated with the electric wire of the isolator such as the vinylchlorid of concentric circles or glue connection vinylchlorid.
The requirement of the recent weather resistance to valve, folding resistance and conductivity is also more and more higher.From saving the angle of the energy, the diameter reducing wire conductor is with weight reduction and save material, but the powered-on capacity of wire conductor is in the past certain, reduces the diameter of wire and it also reduces reduction by capacity.And the reduction of wire conductor diameter causes folding quality to decline, therefore existing electric wire cannot meet these requirements.
Summary of the invention
The object of this invention is to provide the improvement of a Cu alloy material, intensity and the specific conductivity of copper alloy can be improved by this technical scheme, also ensure while making to ensure powered-on capacity when reducing diameter valve or improve folding quality.
The present invention is achieved by the following technical solutions:
A kind of copper alloy for valve, the composition composition of described copper alloy is by weight percentage: the nickel of 1.0-1.3%, the aluminium of 0.5-1.0%, the boron of 0.01-0.03%, the manganese of 0.1-0.3%, the zinc of 0.3-0.8%, the silicon of 0.4-0.6%, the lanthanide rare metal of 0.001-0.05%, all the other are copper and inevitable impurity.
The composition composition of described Cu alloy material includes by weight percentage further: the tin of 0.1-0.6%, the chromium of 0.01-0.1%, 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%.
The composition composition of described Cu alloy material includes by weight percentage further: the magnesium of 0.08-0.2%.
According to the preparation method of above-mentioned every copper alloy for valve, comprise the following steps:
High-frequency melting stove is used each component to be melted, liquation is bred 10-30 minute at 1200-1300 DEG C of constant temperature, then to be not less than 10 DEG C/min of cooling 150-200 DEG C, and then be warming up to 1200-1300 DEG C, copper base is cast after constant temperature 10-30 minute, lead to direct supply or electromagnetic field 5 minutes at the two ends of copper base, after copper base is carried out hot extrusion at 900 DEG C, quench treatment obtains pole immediately, then cold drawnly obtains line material.
The invention has the beneficial effects as follows;
1, by adding lanthanide rare metal and boron in the inventive solutions, the erosion resistance of copper alloy effectively can be improved.
2, by using direct supply or electromagnetic field aborning, making the marshalling organizing interior crystal, and by the change of temperature, being conducive to the even of crystal grain in organizer.
Embodiment
Below by way of specific embodiment, the present invention is described in detail.
Each composition is measured all by weight percentage in the present invention.
The element adding the intensity in order to improve copper alloy of nickel and silicon, forms by nickel and silicon the intensity that tantnickel precipitate improves copper alloy in copper alloy, and the weight percent content of nickel is 1.0-1.3%, and the weight percentage of silicon is 0.4-0.6%.
In the technical program, add lanthanide rare metal, this rare earth metal can change the crystal arrangement of copper alloy inside, improves the erosion resistance of copper alloy, and the consumption the lanthanide rare metal be suitable in the present invention is 0.001-0.05%.Certainly can increase the consumption of lanthanide rare metal, but increase according to the purposes of valve the cost too much improving copper alloy on the contrary.
Copper alloy of the present invention, also includes the aluminium of 0.5-1.0%, the boron of 0.01-0.03%, the manganese of 0.1-0.3%, the zinc of 0.3-0.8%.
For copper alloy of the present invention, can also contain at least one in tin, iron, chromium, cobalt, phosphorus, in these elements, phosphorus can increase the intensity of Cu alloy material, but consumption too much can affect the toughness of copper alloy.Improve bending endurance quality while other several elements can increase Cu alloy material intensity, concrete consumption is the iron of the phosphorus of the cobalt of the chromium of the tin of 0.1-0.6%, 0.01-0.1%, 0.05-1.0%, 0.01-0.05%, 0.05-0.1%.
Can also select magnesium elements in the present invention, this element can prevent from adding thermal embrittlement and improving in hot workability have very large advantage, is conducive to reducing diameter valve.The consumption of magnesium elements is the magnesium of 0.08-0.2% in the present invention.
Preparation method of the present invention is, high-frequency melting stove is used each component to be melted, liquation is bred 10-30 minute at 1200-1300 DEG C of constant temperature, then to be not less than 10 DEG C/min of cooling 150-200 DEG C, and then be warming up to 1200-1300 DEG C, cast copper base after constant temperature 10-30 minute, lead to direct supply or electromagnetic field 5 minutes at the two ends of copper base, after copper base is carried out hot extrusion at 900 DEG C, quench treatment obtains pole immediately, then cold drawnly obtains line material.
