Problems solved by technology

This is mainly because copper is inactive and has strong anti-corrosion properties. However, in these fields, the contact with water and other liquids and the environment will still have a certain corrosion effect on this type of equipment. We can often find it at home or other places. The pipes or valves have green patina, which not only affects the appearance but also reduces the service life of these materials

Embodiment Construction

[0011] The present invention will be described in detail below through specific examples.

[0012] In the present invention, each component is measured by weight percentage.

[0013] The addition of nickel and silicon is an element to improve the strength of the copper alloy. The strength of the copper alloy is improved by forming silicon-nickel precipitates in the copper alloy through nickel and silicon. The weight percentage content of zinc is 33.5-36%, and the weight percentage content of nickel It is 1.5-3.5%, and the weight percentage of silicon is 0.4-0.6%. Also included in this application are 0.4-0.8% aluminum, 0.01-0.3% scandium, and 0.3-0.5% titanium.

[0014] For the copper-zinc alloy material of the present invention, it may also contain at least one of tin, cobalt, and phosphorus. Among these elements, phosphorus can increase the strength of the copper alloy material, but excessive use will affect the toughness of the copper alloy material. Several other element...

Abstract

The invention relates to a copper-zinc alloy material. The copper-zinc alloy material comprises, by weight, 1.5%-3.5% of nickel, 0.4%-0.8% of aluminum, 0.01%-0.3% of scandium, 0.3%-0.5% of titanium, 0.4%-0.6% of silicon, 33.5%-36% of zinc and the balance copper and inevitable impurities. The copper-zinc alloy material has high tensile strength, good fracture resistance and high corrosion resistance.

Description

technical field [0001] The invention belongs to the field of functional alloy materials, in particular to a copper-zinc alloy material. Background technique [0002] Currently, about 58% of the copper and copper alloys consumed in our country are used in the field of electrical engineering, and about 20% of the copper or copper alloys are used in the fields of pipes or valves. This is mainly because copper is inactive and has strong anti-corrosion properties. However, in these fields, the contact with water and other liquids and the environment will still have a certain corrosion effect on this type of equipment. We can often find it at home or other places. Some pipes or valves have green patina, which not only affects the appearance but also reduces the service life of these materials. [0003] In order to reduce the corrosion of copper and copper alloys, researchers have been continuously studying the composition of copper alloys. It is known that copper-zinc alloys are ...
