Description

technical field [0001] The invention relates to a corrosion-resistant copper alloy material for a sensor chip, which is a copper alloy material suitable for a sensor chip and has a strong corrosion-resistant function, and belongs to the field of alloy materials. Background technique [0002] Copper alloys are widely used in automotive parts, home appliance parts, electrical, electronic, optical parts, piping components, plumbing metal parts, and various valves. In addition, due to global warming in recent years, there has been a strong demand for products or components to be smaller, lighter, and thinner. In copper alloys, which have a higher specific gravity than iron, it is necessary to increase the strength to meet these requirements. [0003] Especially in the field of meteorological machinery and meteorological optical instruments, there is a high requirement for the weight of the instrument, as well as a high requirement for the precision of the instrument, so it is ne...
