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

Abstract

The invention relates to the technical field of alloy materials and particularly relates to copper-zinc alloy. The copper-zinc alloy comprises the following components in percentage by weight: 60%-70% of copper, 2.5%-8% of manganese, 0.2%-4% of silicon, 0.2%-3% of iron, 0.1%-0.8% of cobalt, 0-2% of nickel, 0-0.4% of tin and the balance of zinc and unavoidable impurities. The copper-zinc alloy further comprises one or combination of following components in percentage by weight: 1.5%-6% of aluminum, 0.01%-0.05% of phosphorus and 0.05%-0.2% of magnesium. The copper-zinc alloy is capable of resisting folding and corrosion and high in strength.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a copper-zinc alloy. Background technique [0002] Alloys are substances with metallic properties that are synthesized by two or more metals and nonmetals by a certain method. 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. In order to reduce the corrosion of copper and copper alloys, researchers...
