Processing process method of corrosion-resistant copper-zinc-aluminum alloy material

Abstract

The invention discloses a processing process method of a corrosion-resistant copper-zinc-aluminum alloy material. In the processing process method, a copper-zinc-brass alloy is used as a matrix, and elements such as zinc, aluminum, nickel, silicon, boron, manganese and rare earth are added to achieve the aims of high wear resistance, high corrosion resistance, high-temperature resistance and goodmachinability, thus the material requirements of the ocean development and utilization industry, the seawater desalination and heat transfer industry and other special industries can be met; and the energy is saved and the production cost is reduced. The processing process method uses the copper-zinc-brass alloy as the matrix and comprises the following steps: adding nickel, iron, lead, silicon, manganese, aluminum, zinc, boron and at least one of lanthanum and cerium or mixed rare earth elements in turn, dosing, casting, performing saw cutting, heating, performing hot rolling, milling surfaces, performing cold rough rolling, annealing, rolling to obtain a finished product, annealing the finished product, shearing, packaging and warehousing. If the product is required to be in a hard state, the annealing of the finished product is not performed; the corrosion-resistant copper-zinc-aluminum alloy material strip can be prepared, and the important steps are casting, heating and hot rolling; and the processing process is easy, the method is simple, and labor and time can be saved; and the processing process method is convenient to popularize.

Description

technical field [0001] The invention relates to a processing method for alloy materials, in particular to a processing method for corrosion-resistant copper-zinc-aluminum alloy materials. technical background [0002] At present, the marine development and utilization industry and special industries are the sunrise industries of the national economy.

Problems solved by technology

[0004] At present, all high-performance corrosion-resistant copper alloys are mainly HAl77-2 alloys, HSn70-1 alloys and cupronickel alloys. The main problems are poor corrosion resistance and general processing performance, especially in the production of plates and strips. , the processing technology is difficult, the method is complicated, the work efficiency is low, labor-intensive, time-consuming, energy-consuming, and the production cost is high; and the subsequent use performance and multiple corrosion resistance of the material are poor, which cannot meet the needs of some special industries, such as sea water Farming, geothermal utilization, etc.
