Abstract
The present invention relates to a kind of zinc-copper alloy material, the composition composition of the Copper-zinc alloy material is included by weight percentage：1.5 3.5% nickel, 0.3 0.5% chromium, 0.4 0.6% silicon, 33 36.5% zinc, remaining is copper and inevitable impurity.The tensile strength of Copper-zinc alloy material fracture resistance high and good, decay resistance is stronger.
Description
Technical field
The invention belongs to functional alloy material field, a kind of Copper-zinc alloy material is particularly related to.
Background technology
The copper and copper alloy of existing China consumption every year, except account for 58% for electrical field in addition to, also about 20%
Copper or copper alloy be used for the fields such as tubing or valve.This is primarily due to the performance torpescence of copper, the strong original of antiseptic property
Cause, but in these areas because the liquid such as water of contact and environment still can produce certain corrosiveness to this kind of equipment,
We are often able to find that at home or other local tubing or the viridescent patina of valve knot, this not only influences attractive in appearance also same
Sample reduces the service life of these materials.
In order to reduce the corrosion phenomenon of copper and copper alloy, researcher is also constantly studying the composition of copper alloy always, existing
It is known using most copper-nickel alloys namely often said for ormolu, the highest content of metallic zinc has and reaches in this kind of copper alloy
Percentage by weight is 47%, and this is the electrical conductivity without consideration copper naturally, and to be considered how on the contrary in these areas
Reduce electrical conductivity.
The content of the invention
It is an object of the invention to provide the improvement of a Cu alloy material, the strong of copper alloy can be improved by the technical scheme
Also ensure or improve folding quality while spending, and improve the corrosion resistance of copper alloy simultaneously.
The present invention is achieved by the following technical solutions：
A kind of Copper-zinc alloy material, the composition composition of the Cu alloy material is included by weight percentage：33-36.5%
Zinc, the nickel of 1.5-3.5%, the chromium of 0.3-0.5%, the silicon of 0.4-0.6%, remaining be copper and inevitable impurity.
The composition composition of the Cu alloy material has been further included by weight percentage：The tin of 0.1-0.6%, 0.05-
1.0% cobalt, the phosphorus of 0.05-0.5%, in one or more combination.
The composition composition of the Cu alloy material has been further included by weight percentage：The manganese of 0.02-0.1% and
One or two combinations in the magnesium of 0.08-0.2%.
The beneficial effects of the invention are as follows；
By in technical scheme, on the premise of copper alloy intensity is ensured, and can simultaneously improve copper alloy
Corrosion resistance.
Specific embodiment
Below by way of specific embodiment, the present invention is described in detail.
Each composition is measured by the percentage by weight in the present invention.
The addition of nickel and silicon forms tantnickel analysis by nickel and silicon to improve the element of the intensity of copper alloy in copper alloy
Go out thing to improve the intensity of copper alloy, the weight percent content of zinc is 33-36.5%, and the weight percent content of nickel is 1.5-
3.5%, the weight percentage of silicon is 0.4-0.6%.
For Copper-zinc alloy material of the invention, at least one in tin, cobalt, phosphorus, phosphorus in these elements can also be contained
The intensity of Cu alloy material can be increased, but consumption can excessively influence the toughness of Cu alloy material.Other several elements can
Bending endurance quality is improved while increasing Cu alloy material intensity, specific consumption is the tin of 0.1-0.6%, 0.05-1.0%
Cobalt, the phosphorus of 0.01-0.05% can influence the electrical conductivity of Cu alloy material when the consumption of these elements is excessive.
At least one that can also be selected in two kinds of elements of magnesium and manganese in the present invention, both elements can prevent heating
Brittle and improvement hot-working character aspect has very big advantage, advantageously reduces diameter of wire.But the consumption of both elements surpasses
The electric conductivity of copper alloy can be significantly affected when 0.5%, the consumption of both elements is 0.02-0.1%'s in the present invention
The magnesium of manganese and/or 0.08-0.2%.
Each component is melted into casting copper base using high-frequency melting stove in embodiments of the invention 1-6, by copper base at 900 DEG C
Pure fire treatment immediately obtains semi-finished product copper base after carrying out hot extrusion, and then cold working obtains expecting material.
Specific embodiment above is only capable of as of the invention with reference to rather than limitation of the present invention.
Due to the present invention relates to anti-corrosion layer, therefore by implementing following salt mist experiment, and by a fixed length time
Found corrosion area width is determined afterwards, to make corrosion resistance evaluation substantially.
1), salt mist experiment
Spray chamber, concentration is 5% or so NaCL solution, and pressure is 60-180 kPas of compressed air, can be by temperature
Be maintained at 35 DEG C ± 1 DEG C of temperature controller, relative humidity be 95%-98%, temperature be 35 DEG C ± 1 DEG C under conditions of, to
Each sample sprays the specific long-time of salt solution.
2), sample
Each piece of sample is prepared in the following manner, and one block size of measurement is entered for the ormolu of 30mm × 100mm × 3mm
Row ion implanting simultaneously carries out oxide-film treatment, and with graduating with cutter goes out vestige thereon.
3), evaluate
Using visual type inspection.
