Manganese Copper Alloy Applications

Manganese copper is a precision resistive alloy, usually supplied by wire and in small quantities by sheet and strip. It is widely used in various instruments. It is also an ultra-high pressure sensitive material with an upper limit of pressure measurement up to 500 pa. Having a good piezoresistive effect is a material of manganese copper alloy resistance, which is commonly used for pressure measurement in high temperature and high pressure environments such as new material synthesis and explosive blast and high speed shock and dynamic fracture. The temperature coefficient of resistance is small so the change in resistance of manganese copper is approximately linear with external pressure (i.e., the piezoresistive coefficient K is almost constant). Pressure measurements under dynamic high pressure can be converted into measurements of the change in resistance of manganese copper they are operated by sensors with manganese copper as a sensitive element.
The bmn3-12 manganese copper is a later manganese copper alloy resistance than the Bmn40-1.5 Kang copper alloy resistance. Its advantages are low resistance temperature coefficient and linear relationship of resistance temperature curve is better than bmn3-12 can be used in a wide temperature range; can be used up to 400 ℃ its heat resistance is better than bmn3-12 the maximum use temperature of white copper is 300 ℃ and corrosion resistance is also better than bmn3-12. it also has good processing properties and pin welding properties.

For special sectors such as defense and military, there is an urgent need for direct measurement of higher pressures, and the sensors are required to have very fast response. Progress in the research of manganese copper sensors in these two areas is reviewed.

Properties of copper manganese
The material with good piezoresistive effect is manganese copper, which is commonly used for pressure measurement in high-temperature and high-pressure environments such as new material synthesis and blast and high-speed impact and dynamic fracture. The temperature coefficient of resistance is small so that the resistance of manganese copper changes approximately linearly with the external pressure (i.e., the piezoresistive coefficient K is almost constant). Pressure measurements under dynamic high pressure can be converted into measurements of the change in resistance of manganese copper and they are operated by sensors with manganese copper as the sensitive element.
