Nickel Chrome Alloys

nickel-chrome-alloys

Nickel Chrome Alloys exhibit exceptional electrical resistance properties, making them the material of choice when a heating element is required.

Nickel Chrome Alloys – NC 80/20

nickel-chrome-alloys---nc-80/20

A Nichrome alloy containing long life additions that make it eminently suitable for applications subject to frequent electrical switching and wide temperature fluctuations. It may be used at operating temperatures up to 1200 °C and has good resistance to oxidation and chemical corrosion. A low temperature coefficient of resistance coupled with a high resistivity makes it suitable for control resistors.

Nickel Chrome Alloys – NC 60/16

nickel-chrome-alloys---nc-60/16

A Nichrome alloy containing long life additives and with a composition balance of Iron. It is suitable for use up to 1100 °C, and has good resistance to oxidation and chemical corrosion. It has a medium temperature coefficient of resistance that makes it suitable for less exacting applications than 80/20 Nickel Chrome alloys.

Nickel Chrome Alloys – NC 37/18

nickel-chrome-alloys---nc-37/18

A Nichrome alloy with a composition balance primarily of Iron. It is suitable for continuous operation up to a maximum temperature of 1050 °C and is recommended for furnace use with atmospheres which might otherwise cause dry corrosion for higher nickel content materials. In particular, it has a better resistance to sulphur attack and “green-rot” – a type of corrosion produced by alternating carburisation and oxidation. A large temperature coefficient of resistance means that the change of resistance with increase in temperature must be taken into account during design.
