Abstract

The invention relates to a copper and zinc alloy material, which is prepared from the following raw materials in percentage by weight: 1.5 to 3.5 percent of nickel, 0.4 to 0.8 percent of aluminum, 0.01 to 0.03 percent of zirconium, 0.01 to 0.03 percent of tungsten, 0.01 to 0.3 percent of scandium, 0.3 to 0.5 percent of titanium, 0.4 to 0.6 percent of silicon, 33.5 to 36 percent of zinc and the balance copper and unavoidable impurities. The copper and zinc alloy material has the advantages that the tensile strength is high; good folding-resistant performance is realized; the anti-corrosion performance is good.

Description

A kind of Copper-zinc alloy material

Technical field

The invention belongs to functional alloy material field, particularly relate to a kind of Copper-zinc alloy material.

Background technology

The annual copper consuming of existing China and copper alloy, 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, strong former 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 at home or other local tubing or valve tie viridescent patina, this not only affect attractive in appearance also with Sample reduces the service life of these materials.

In order to reduce the corrosion phenomenon of copper and copper alloy, research worker also always in the continuous composition studying copper alloy, shows Known using most copper-nickel alloys namely often said for ormolu, in this kind of copper alloy, the highest content of metallic zinc has and reaches Percentage by weight is 47%, and this is without the electrical conductivity considering copper naturally, and will consider how on the contrary in these areas Reduce electrical conductivity.

Content of the invention

It is an object of the invention to provide a kind of improvement of Cu alloy material, copper alloy can be improved by this technical scheme Also ensure or improve folding quality while intensity, 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 described copper alloy includes by weight percentage: 33.5-36%'s Zinc, the nickel of 1.5-3.5%, the aluminum of 0.4-0.8%, the zirconium of 0.01-0.03%, the tungsten of 0.01-0.03%, 0.01-0.3%'s Scandium, the titanium of 0.3-0.5%, the silicon of 0.4-0.6%, remaining is copper and inevitable impurity.

The composition composition of described Cu alloy material further includes by weight percentage: the stannum of 0.1-0.6%, 0.1- 0.8% cobalt, the phosphorus of 0.05-0.5%, one or more of combination.

Described Cu alloy material composition composition further include by weight percentage: the manganese of 0.02-0.1% and One of magnesium of 0.08-0.2% or two kinds of combinations.

The invention has the beneficial effects as follows；

By in technical scheme, on the premise of ensureing copper alloy intensity, and copper alloy can be improved simultaneously Corrosion resistance.

Specific embodiment

Below by way of specific embodiment, the present invention is described in detail.

Each composition is all measured by the percentage by weight in the present invention.

The addition of nickel and silicon, in order to improve the element of the intensity of copper alloy, forms tantnickel analysis by nickel and silicon in copper alloy Go out thing to improve the intensity of copper alloy, the weight percent content of zinc is 33.5-36%, and the weight percent content of nickel is 1.5- 3.5%, the weight percentage of silicon is 0.4-0.6%.The aluminum of 0.4-0.8% is also included in the application, 0.01-0.03%'s Zirconium, the tungsten of 0.01-0.03%, the scandium of 0.01-0.3%, the titanium of 0.3-0.5%.

For the Copper-zinc alloy material of the present invention, can also be containing at least one in stannum, cobalt, phosphorus, phosphorus in these elements The intensity of Cu alloy material can be increased, but consumption excessively can affect the toughness of Cu alloy material.Other several elements can Increase and while Cu alloy material intensity, improve bending endurance quality, specific consumption is the stannum of 0.1-0.6%, 0.1-0.8% Cobalt, the phosphorus of 0.01-0.05%, the electrical conductivity of Cu alloy material can be affected when the consumption of these elements is excessive.

Can also be from least one in magnesium and two kinds of elements of manganese in the present invention, both elements can prevent from heating Brittle and improve hot-working character aspect and have very big advantage, advantageously reduce 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 Manganese and/or the magnesium of 0.08-0.2%.

Using high-frequency melting stove, each component is melted casting copper base in embodiments of the invention 1-6, by copper base at 900 DEG C After carrying out hot extrusion, pure fire process obtains semi-finished product copper base immediately, and then cold working obtains expecting material.

Above specific embodiment is only capable of reference rather than limitation of the present invention as the present invention.

Due to the present invention relates to anti-corrosion layer, therefore passing through to implement following salt mist experiment, and through a fixed length time Determine found corrosion area width afterwards, to make corrosion resistance evaluation substantially.

1), salt mist experiment

Spray chamber, concentration is 5% about nacl solution, and pressure is 60-180 kPa of compressed air, can be by temperature It is maintained at 35 DEG C ± 1 DEG C of temperature controller, be 95%-98% in relative humidity, under conditions of temperature is 35 DEG C ± 1 DEG C, to Each sample injection saline is specific long-time.

2), sample

Prepare each piece of sample in the following manner, measurement one block size is that the ormolu of 30mm × 100mm × 3mm enters Row ion implanting simultaneously carries out oxide-film process, and go out vestige with graduating with cutter thereon.

3), evaluate

Using visual type inspection.

Composition in each specific embodiment and performance are shown in Table 1

Table 1

By above example, comprise only nickel, the very high decay resistance simultaneously of intensity of the copper alloy of silicon and zinc is outstanding.
