Copper-based heating resistance alloy bar has lower electrical resistance,good echanical,excellent welding
and anti-corrosion properties.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.
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
