Preparation method of corrosion-resistant arsenic-containing brass for forming elbow easily

The invention discloses a preparation method of corrosion-resistant arsenic-containing brass for forming an elbow easily. The preparation method mainly comprises the steps of material proportioning, smelting, casting, hot extrusion, annealing and surface treatment. Arsenic is added into a brass alloy, the contents of all the components are optimized and controlled, and the unique smelting and annealing processes are adopted, so that the cutting performance of a copper alloy can be improved to reach the cutting performance of lead brass, the lead content is reduced, and the corrosion-resistantarsenic-containing brass is harmless and environmentally friendly; and meanwhile, the surface of the alloy is treated through a specific compound corrosion inhibitor, so that the problem of corrosioncaused by a low lead content is solved effectively, and the corrosion resistance of the brass alloy is improved. 本发明公开了种耐腐蚀易弯管成型的加砷黄铜制备方法；主要包括配料、熔炼、引铸、热挤压、退火、表面处理；通过在黄铜合金中加入砷，并优化及控制各组分的含量，结合特有的熔炼及退火工艺，可提高铜合金使其达到铅黄铜的切削性能，降低铅的含量
