Pressure gauge copper connector and manufacturing method thereof

The invention relates to a pressure gauge copper connector and a manufacturing method thereof, and belongs to the technical field of a copper connector. The pressure gauge copper connector comprises copper, iron, silicon, manganese, nickel, lanthanum, lead, zinc and the like, and is manufactured by a one-time punch forming method. In the pressure gauge copper connector obtained by the method, thetensile strength reaches to 700 MPa or more, the elongation percentage reaches to 10 percent or more and the rejection rate is reduced to 2 percent or less. 压力表铜接头及其制备方法，属于铜接头技术领域。压力表铜接头由铜、铁、硅、锰、镍、镧、铅、锌等构成，其采用次性冲压成型的方法制得。本发明得到的压力表铜接头抗拉强度达到700MPa以上，延伸率达到10%以上，本发明的报废率降至2%以下。
