Feature
The alloy is Characterized by very low thermal eelctromotives force (emf) compared to copper.
Application
6J12 IS Typically used for the manufacturing of resistance standards,precision wire resistors,potentiometers,shunts and other electrical and electronic components.
6j12 widely used for precision resistors with the highest requirements,the resistors should be carefully stabilised and the application temperature should not exceed +60℃.Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidixing .Thus,the long term stability can be affected negatively.As a result,
the resistivity as well as the temperature coefficient of the elextric resistance may slightly change.
It is also used as low cost replacement material for silver solder for hard metal mounting.The alloy's low emf vs copper makes it deal for use in electrical circuits,especially D.C., where a spurious thermal emf could cause malfunctioning of electronic equipment .Due to the low operating temperature,the temperature coefficient of resistance is controlled to be low over a range of 15 to 35℃.
