Main uses:

Manganese-copper and Xinkang-copper alloys are widely used in precise measurement of voltage, current and resistance, bridges and point-to-point differential meters, electrical instruments such as ammeters and voltmeters indicating these quantities, and winding resistors, shunt resistors and sliding resistors in measuring, indicating, regulating and recording instruments. In addition, it is more suitable for standard resistors with a nominal resistance value and as a reference. In addition, manganese copper, copper and nickel are also heating wires for low temperature heating elements. Such as: air-conditioned train cabin heating, household heating appliances, etc.
