Product Description

Copper Alloy Wire constantan manganin

nickel and strengthening impurities, such as iron and manganese.
Cupronickel does not corrode in seawater,
because its electrode potential is adjusted to be neutral with regard to seawater.
Because of this it is used for marine hardware,
and sometimes for the propellers,
crankshafts and hulls of premium tugboats,
fishing boats and other working boats.
TANKII alloy, Always best quality, favourable price.

Application of Manganin
Manganin foil and wire is used in the manufacture of resistor, Particularly ammeter shunt, because of its virtually zero temperature coefficient of resistance value and long term stability.
