Nickel DH is a nickel alloy (Ni alloy) with a minimum nickel content of 99.2 % suitable for use at temperatures up to 600°C (1100°F).
Typical applications for Nickel DH are lamp filaments filters and many industrial and laboratory equipment where there is need for good corrosion resistance. It is also often used as a resistor when high variation of resistance with temperature is required.
