CM44　Copper Nickel Mangan

Code：CM44 (Copper Nickel Mangan）

Properties and Applications

Since it has poor resistance to corrosion and oxidation, it is desirable to use it with a moisture-proof and oxidation-resistant coating. It is non-magnetic.Can be used up to 150℃. Small temperature coefficient of resistance and thermal electromotive for
