Abstract
The invention relates to a zinc-copper alloy material. The copper-zinc alloy material comprises the components of, by weight: 1.5-3.5% of nickel, 0.4 - 0.6% of silicon, 33 to 36.5% of zinc, and balance of copper and unavoidable impurities. The copper-zinc alloy material has high tensile strength, good bending strength, and high corrosion resistance.
Description
Technical field
The invention belongs to the functional alloy material field, refer to especially a kind of copper zinc alloy material.
Background technology
Annual copper and the copper alloy that consumes of existing China except accounting for 58% be used for the electrical field, also has about 20% copper or copper alloy to be used to the fields such as tubing or valve.This mainly is because the performance torpescence of copper, the reason that antiseptic property is strong, but in these fields because the liquid such as water of contact and environment still can produce certain corrosive nature to this class equipment, we often can find at home or other is local tubing or valve are tied viridescent patina, and this not only affects the work-ing life that reduces too these materials attractive in appearance.
In order to reduce the corrosion phenomenon of copper and copper alloy, the researchist is also always at the composition of constantly studying copper alloy, use maximum copper-nickel alloys of namely often saying as copper zinc alloy known to existing, the weight percent of reaching is arranged is 47% to the high-content of metallic zinc in this class copper alloy, this is the specific conductivity that need not consider copper naturally, and what will consider on the contrary in these fields is how to reduce specific conductivity.
Summary of the invention
The purpose of this invention is to provide the improvement of a Cu alloy material, also guarantee when can improve the intensity of copper alloy by this technical scheme or improve folding quality, and improve simultaneously the corrosion resistance of copper alloy.
The present invention is achieved by the following technical solutions:
A kind of copper zinc alloy material, the composition composition of described Cu alloy material includes by weight percentage: the zinc of 33-36.5%, the nickel of 1.5-3.5%, the silicon of 0.4-0.6%, all the other are copper and inevitable impurity.
The composition of described Cu alloy material forms and further includes 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 combinations.
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%.
The invention has the beneficial effects as follows;
By in technical scheme of the present invention, can be under the prerequisite that guarantees copper alloy intensity, and improve simultaneously the corrosion resistance of copper alloy.
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 zinc is 33-36.5%, the weight percent content of nickel is 1.5-3.5%, 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 a in tin, 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.When can increasing Cu alloy material intensity, improve other several elements the bending endurance quality, 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 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.
Use the high-frequency melting stove that each component is melted casting copper base among the embodiments of the invention 1-6, the immediately quench processing after carrying out hot extrusion under 900 ℃ of copper base is obtained work in-process copper base, then cold working obtains expecting material.
Above specific embodiment only can be as reference of the present invention rather than limitation of the present invention.
Owing to the present invention relates to anti-corrosion layer, the therefore salt mist experiment below implementing, and determining the corrosion area width found after long-time through certain, to make erosion resistance evaluation substantially.
1), salt mist experiment
The spray chamber, concentration is about 5% NaCL solution, pressure is 60-180 kPa pressurized air, temperature can be remained on 35 ℃ ± 1 ℃ temperature regulator, be 95%-98% in relative humidity, temperature is under 35 ℃ ± 1 ℃ the condition, to spray salt solution to each sample specific long-time.
2), sample
Prepare in the following manner each piece sample, measure a copper zinc alloy that is of a size of 30mm * 100mm * 3mm and carry out ion implantation and carry out oxide film and process, and go out vestige with graduating with cutter thereon.
3), estimate
The employing visual type checks.
Composition and performance in each specific embodiment are shown in Table 1
Table 1
By above embodiment, only include nickel, the copper alloy of silicon and zinc the very high while corrosion resistance nature of intensity outstanding.
