Abstract

The invention discloses a non magnetic corrosion-resistant copper alloy material. It is characterized in that the components and their weight proportion are as follows: Ni 0.05-2%, Al 2-15%, Zn 0.5-8%, 5 Sn 1-10%, and the left are Cu. The non magnetic corrosion-resistant copper alloy material is prepared by adding alloy element with suitable amount, and it possesses good corrosion-resitance property, especially in salty water and atmosphere condition, stable diamagnetism, wide application in ship building industry and instrument material.

Description

technical field [0001] The invention relates to a non-magnetic corrosion-resistant copper alloy material. Background technique [0002] Nature is full of various magnetic fields, and there are different corrosions in different natural environments. It can not only have good corrosion resistance in the atmosphere and saline water, but also resist magnetic field interference. It has become an increasingly important material in modern industry. The more urgent the request. Copper not only has good corrosion resistance in the atmosphere and saline water, but also the copper ions dissolved in water have a bactericidal effect, which can prevent biofouling in salt water. Copper alloys are usually used in both salt water and atmospheric environments with poor corrosion resistance and poor antimagnetic properties. After being used as a device protective cover for a period of time, the direction finding accuracy of the internal equipment will increase by mistake, affecting the direct...
