Professional China Precision Wire Wound Resistors - Manganin Wire – TANKII
Professional China Precision Wire Wound Resistors - Manganin Wire – TANKII Detail:
Product Description
Manganin Wire is of copper-nickel alloys that are used for electrical and controlled resistance applications. These alloys have very low temperature coefficient of resistance, and offer uniform electrical resistance over long periods of time. Additionally, they have very low thermal electromotive force (EMF) against copper. These alloys have good workability, can be soldered, as well as welded.
