Abstract
The invention relates to a copper alloy material for a valve. The copper alloy material comprises, by weight percentage, 1.5-3.0% of nickel, 0.3-0.5% of zirconium, 0.1-0.3% of vanadium, 0.4-0.6% of silicon, 33-36.5% of zinc, and the balance copper and inevitable impurities. The copper-zinc alloy material is high in tensile strength, good in bending resistance and high in corrosion resistance.
Description
Technical field
The invention belongs to functional alloy material field, refer to a kind of for valve Cu alloy material especially.
Background technology
The Copper and its alloy that existing China consumes every year, except account for 58% for except electrical field, also have the copper of about 20% or copper alloy to be used to the field such as tubing or valve.This is mainly because the performance torpescence of copper, the reason that antiseptic property is strong, but in these areas because the liquid such as the water of contact and environment still can produce certain corrosive nature to this kind of equipment, we often can find at home or the tubing in other place or valve tie viridescent patina, and this not only affects the work-ing life reducing these materials too attractive in appearance.
In order to reduce the corrosion phenomenon of Copper and its alloy, researchist is also always at the composition constantly studying copper alloy, the copper-nickel alloy namely often said for copper zinc alloy that existing known use is maximum, in this kind of copper alloy, the most high-content of metallic zinc has that to reach weight percent be 47%, this is the specific conductivity need not considering copper naturally, and wants it is considered that how to reduce specific conductivity on the contrary in these areas.
Summary of the invention
The object of this invention is to provide a kind of improvement of Cu alloy material, also ensure the intensity of copper alloy can be improved by this technical scheme while or improve folding quality, and improve the corrosion resistance of copper alloy simultaneously.
The present invention is achieved by the following technical solutions:
For a Cu alloy material for valve, the composition composition of described Cu alloy material includes by weight percentage: the zinc of 33-36.5%, the nickel of 1.5-3.0%, the zirconium of 0.3-0.5%, the vanadium of 0.1-0.3%, the silicon of 0.4-0.6%, all the other are copper and inevitable impurity.
Described Cu alloy material composition composition include further by weight percentage: the tin of 0.1-0.6%, the cobalt of 0.05-1.0%, the phosphorus of 0.05-0.5%, in one or more combination.
The composition composition of described Cu alloy material includes by weight percentage further: one or both combinations in the manganese of 0.02-0.1% and the magnesium of 0.08-0.2%.
The invention has the beneficial effects as follows;
By in technical scheme of the present invention, under the prerequisite ensureing copper alloy intensity, and the corrosion resistance of copper alloy can be improved simultaneously.
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, in copper alloy, the intensity that tantnickel precipitate improves copper alloy is formed by nickel and silicon, the weight percent content of zinc is 33-36.5%, the weight percent content of nickel is 1.5-3.0%, and the weight percentage of silicon is 0.4-0.6%.
For Copper-zinc alloy material of the present invention, can also contain at least one in tin, cobalt, phosphorus, in these elements, phosphorus can increase the intensity of Cu alloy material, but consumption too much can affect the toughness of Cu alloy material.Bending endurance quality is improved while 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%, can affect the specific conductivity of Cu alloy material when the consumption of these elements is too much.
Can also select at least one in magnesium and manganese two kinds of elements in the present invention, these two kinds of elements can prevent from adding thermal embrittlement and improving in hot workability have very large advantage, are conducive to reducing diameter of wire.But obviously can affect the conductivity of copper alloy when the consumption of these two kinds of elements is more than 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.
Use high-frequency melting stove each component to be melted casting copper base in embodiments of the invention 1-6, after copper base is carried out hot extrusion at 900 DEG C, quench process immediately obtains work in-process copper base, and then cold working obtains expecting material.
Above specific embodiment only can as reference of the present invention instead of limitation of the present invention.
Owing to the present invention relates to anti-corrosion layer, therefore by implementing salt mist experiment below, and after a fixed length time, determining found corrosion area width, to make erosion resistance evaluation substantially.
1), salt mist experiment
Spray chamber, concentration is the NaCL solution of about 5%, and pressure is the pressurized air of 60-180 kPa, temperature can be remained on the temperature regulator of 35 DEG C ± 1 DEG C, be 95%-98% in relative humidity, temperature is under the condition of 35 DEG C ± 1 DEG C, sprays salt solution for a long time specific to each sample.
2), sample
Prepare each block sample in the following manner, measure one block of copper zinc alloy being of a size of 30mm × 100mm × 3mm and carry out ion implantation and carry out oxide film process, and go out vestige with graduating with cutter thereon.
3), evaluate
Employing visual type checks.Composition in each specific embodiment and performance are shown in Table 1
By above embodiment, only include nickel, the copper alloy of silicon and zinc intensity very high while corrosion resistance nature outstanding.
