The present invention relates to a silicon tin brass alloy. It is characterized in that the silicon brass alloy composed of tin content is 66 ~ 75wt%, 0.4 ~ 3.3wt% silicon copper, chromium, 0.5 ~ 1.0wt% 0.03 ~ 1.1wt% 0.1 ~ 0.66wt% of tin, nickel, titanium, lead 0.001 ~ 0.11wt%, less than 0.2wt%, the remaining is the zinc and unavoidable impurities, unavoidable impurity amount is not more than 0.2wt%. The invention improves the cutting performance and forging performance of the alloy by replacing silicon with silicon instead of lead. Tin improves the cutting performance and dezine corrosion resistance of the alloy, and fines the grain with titanium. Compared with lead brass, the invention has a trace of lead, and eliminates the harm of lead in the process of production and use to the human body and the environment as much as possible. Compared with the existing silicon - containing environmental brass, the cutting performance is significantly improved and the cost is low.

硅锡黄铜合金生产方法
本专利技术涉及一种硅锡黄铜合金。
技术介绍
黄铜具有美观的外表和优异的性能,在仪器仪表、电子电气、日用五金、水暖阀门等领域中大量应用,其中尤以HPb59-1生产、应用量最大。目前锻造用黄铜大多含锌为35~45wt%,属于α+β双相黄铜。这类黄铜在高温下塑性极好,因此适合于热锻加工。为了改善锻造后机加工和切削性能,在这种黄铜中加入少量铅(约0.8~3.5%),从而为加工形状复杂的日用品和水暖阀门零部件带来了便利。
