Description

Omega nickel-chromium alloy resistance heating wire is available coiled for ready use. Coiled heating wire is used in many high-temperature applications, including electric furnaces, radiant heaters, and air heating.

NIC80 is an alloy of 80% nickel and 20% chromium and represents the highest standard in materials for use in elevated temperature environments. It is useable at temperatures up to 1150°C.

NIC60 contains 60% nickel and 16% chromium, with the balance iron, and can be used up to 1000°C. It is the most commonly used wire in electrical heating applications.

Both of these alloys also provide excellent corrosion resistance.
