Main uses
Manganin 6j8, 6j12 and 6j13 are superior precision resistance alloy materials because of their small resistance, temperature coefficient, low electrothermal potential to copper, high resistance stability and high resistivity. It is widely used in precision measurement of voltage, current and resistance, bridge and potentiometer, ammeter, voltmeter and other electrical instruments indicating these quantities, as well as winding resistor, shunt resistor and sliding resistor in measuring, indicating, regulating and recording instruments. In addition, it is more suitable for the standard resistor with a certain nominal resistance value and used as a reference. In addition, manganese copper and copper nickel are also heating wires of low temperature heating elements. For example, air-conditioned train bus box heating, household heating appliances.
The supply status is generally soft, or hard or semi hard according to the needs of users;
The supply specification can also supply special shape and size (plate, strip, bar, block) alloy materials according to the requirements
