The invention belongs to the technical field of copper alloys, and particularly relates to a low-bismuth graphite brass alloy and a preparation method and application thereof. The preparation method comprises the following steps: smelting preparation raw materials according to the composition of elements in the low-bismuth graphite brass alloy to obtain a melt; the preparation raw materials comprise a Cu raw material, nodular cast iron, a Zn raw material, a Bi raw material and a Sn raw material; and the melt is cast, and the low-bismuth graphite brass alloy is obtained. Spheroidal graphite is introduced by using nodular cast iron, the problem that graphite and copper are immiscible is solved, meanwhile, the cutting performance of the low-bismuth graphite brass alloy is supplemented, on one hand, use of precious metal bismuth is reduced, and therefore the production cost is reduced; and on the other hand, the spheroidal graphite is beneficial to improving the mechanical property of the brass alloy, so that the brass alloy with high mechanical property and good cutting property is obtained, and the brass alloy is beneficial to being used in water conveying and distribution equipment.
本发明属于铜合金技术领域，具体涉及一种低铋石墨黄铜合金及其制备方法和应用。本发明按照所述低铋石墨黄铜合金中元素的组成，将制备原料进行熔炼，得到熔体；所述制备原料包括Cu原料、球墨铸铁、Zn原料、Bi原料和Sn原料；将所述熔体进行浇铸，得到所述低铋石墨黄铜合金。本发明通过使用球墨铸铁引入球状石墨，解决了石墨与铜不互溶的问题，同时对低铋石墨黄铜合金的切削性能进行补充，一方面降低贵金属铋的使用，从而降低生产成本；另一方面，球状石墨有利于提高黄铜合金的力学性能，从而得到一种力学性能高、切削性能好的黄铜合金，有利于其在输配水设备中的使用。
