| description | The invention discloses a marine-corrosion-resistant copper alloy material for deep and far sea aquaculture. The preparation method comprises the following steps: burdening-casting; casting the material into a wire blank or an ingot blank according to requirements; after the material is cast into a wire blank, stretching, annealing, pickling, stretching and inspecting are carried out; after the material is cast into an ingot blank, heating, hot rolling, surface milling, cold rolling, annealing, finish rolling, cleaning and inspecting are carried out; the materials comprise 78%-90% of Cu, 2%-4% of Al, 1%-2% of Co, 1%-2% of Mn, 0.003%-0.1% of Sr and the balance Zn and inevitable impurities, and the sum of all the components is 100%; according to the brass material produced by the invention, through alloying design, the seawater corrosion resistance and long-term erosion corrosion resistance of flowing seawater in deep and far sea are improved, and meanwhile, the brass material has the advantages of high strengt |
