A kind of seawater corrosion-resistant copper alloy containing zirconium and its preparation method

Abstract

The invention provides seawater-corrosion-resistant copper alloy containing zirconium. The seawater-corrosion-resistant copper alloy containing zirconium is prepared from, by mass percent, 63%-75% of Cu, 0.05%-1.5% of Al, 1.91%-3.5% of Si, 0.26%-2.0% of P, 0.0008%-0.006% of Zr and the balance Zn, and the copper alloy is in a single alpha phase. The invention further provides a preparation method of the copper alloy. By mass percent, the reaction substances are weighed, wherein Cu, Al, Zr, Si and Zn are elementary substances, and P is added in the manner of Cu-P intermediate alloy; and the above substances are added into a reaction vessel, smelting is performed for 2-5 hours at the temperature of 1000-1200 DEG C, and the seawater-corrosion-resistant copper alloy is obtained after cooling. The seawater-corrosion-resistant copper alloy is resistant to long-time corrosion of seawater, meanwhile, other performance of brass is not damaged, and the alloy has the beneficial effects of being high in strength, good in machining performance, high in hardness and resistant to seawater scouring.

Description

technical field

[0001] The invention belongs to the field of nonferrous metals and relates to an alloy, in particular to a seawater corrosion-resistant copper alloy containing zirconium and a preparation method thereof. Background technique

[0002] In recent years, fish farming has become a rapidly developing industry, but the materials used in traditional farming barbed wire and shellfish farming trays are plastic nets made of synthetic fibers. However, the use of this material is prone to fouling in the seawater farming process , A large amount of dirt will not only block the mesh of the sea culture tank, increase the difficulty and cost of cleaning, but also reduce the flow of sea water and affect the healthy growth of farmed fish. Due to the problems with synthetic fiber fishing net materials, there is now a trend to use copper alloy cages. The advantages of copper alloy mesh cages are as follows: 1. Prevent biological pollution, reduce costs, avoid fish stress and the...
