Product Details
Copper nickel alloy,which has low electric resistance,good heat-resistant and corrosion-resistance,easy to be processed and lead welded.It is used to make the key components in the thermal overload relay,low resistance thermal circuit breaker,and the electrical applicances.It is also an important material for electrical heating cable.It is similar as Kanthal's type cupronickel.
Principally destined for the manufacturing of low temperatures electric resistances so as heating cables,shunts,resistancces for automobile,they have a maxximum operating temperature of 752℉.
They do not therefore intervene in the field of resstances for industrial furnaces.
The most known,CuNi44(also called Constantan)presents the advantage of a very low temperature coefficient.
Their advantages are the following:
Very good resistances to corrosion.
Very good malleability
Very good solderability
