General Details
Comprises 80% nickel and 20% chromium. Its awe-inspiring ability to quickly heat up and rapidly cool down with a mere flick of an electrical switch, makes it ideally suited to the manufacture of heating elements for electrical home appliances. Its greater resistance properties and high melting-point justify its usage as a resistor in high-temperature applications, such as high-speed fuses, electric industrial furnaces, electric ranges and radiant heaters. It can have an operating temperature up to 1150°C (2100°F). It has a long service life and demonstrates non-magnetic properties.
