Embodiment Construction

[0013] An antifouling and seawater corrosion-resistant copper alloy material, which contains chemical element components and mass percentages: zinc 21-23, tin 5-6, Ti0.8-1.0, Ta0.04-0.06, Mg0.9- 1.2, La0.01-0.05, the balance is copper.

[0014] The production method of the described antifouling and seawater corrosion-resistant copper alloy material is as follows:

[0015] (1) Prepare pure copper and scrap copper as the source of copper matrix in a ratio of 1:0.8, add pure copper into the furnace for melting, remove impurities, deoxidize, refine once with refining agent, add alloy components for alloying, and then add Scrap copper melting, adding refining agent for secondary refining, testing and adjusting the content of chemical elements to pass, casting, post-casting heat treatment, etc.;

[0016] (2) The batch order of alloying elements into the furnace during the alloying process is: (1) Zinc; (2) Tin, Ta; (3) Other remaining components; the time interval between each batc...

Abstract

An antifouling sweater-corrosion-resistant copper alloy material comprises the chemical elements in percent by mass: 21-23% of Zn, 5-6% of Sn, 0.8-1.0% of Ti, 0.04-0.06% of Ta, 0.9-1.2% of Mg, 0.01-0.05 of La and the balance Cu. By adding Ti and Mg into tin brass alloy, the copper alloy is improved in anti-oxidation performance and strength; by adding Ta and La, the alloy is good in cutting performance and electrical conductivity; and by reasonably controlling the processing temperature after casting and taking waste copper as a raw material, the hardness of the core part and the hardness of the surface are basically consistent, and the alloy quality is uniform. The copper alloy is usable as mechanical parts for offshore operations, is capable of preventing apposition growth of marine organisms and is resistant to seawater corrosion. An employed refining agent is used for casting production, is capable of reducing the porosity degree of a casting by 1-2 degree and enabling the oxide inclusions to be around second grade, and helps to obviously improve the yield.

Description

technical field [0001] The invention relates to the field of manufacturing metal alloy materials, in particular to an antifouling and seawater corrosion-resistant copper alloy material and a preparation method thereof. Background technique [0002] Copper is widely used because of its good electrical conductivity, plasticity and corrosion resistance. Adding elements such as aluminum, nickel, manganese, tin, silicon, and lead to copper alloy can improve the performance of copper and be used in different places. At present, there are still some problems in the existing copper alloys in my country, such as the alloy contains a large number of impurity elements, poor high temperature fatigue, low high temperature strength; low hardness, poor wear resistance, large friction coefficient, short service life; poor conductivity, waste of electric energy; bending The processing performance is poor and it is easy to break; the quality is heavy and the construction is difficult; it cann...
