Heater Wire

 

Nichrome Wire Type - A | Nichrome Wire Type - C

The Arklay S. Richards Co., Inc. offers two types of Nichrome Heater Wire. The Richards NWA or Type A Nichrome Heater Wire is composed of 80% Nickel and 20% Chromium. The Type A wire has a lower temperature coefficient of resistance when compared to the Type C Nichrome Wire. The Type A Nichrome Wire has a usable temperature range up to 1150°C or 2100°F.

Richards NWC or Type C Nichrome Heater Wire is composed of 60% Nickel, 16% Chromium, and the balance of 24% Iron. Type C wire has a usable temperature range up to 1000°C or 1850°F. It also has a higher coefficient of resistance when compared to the Type A wire. Both types of Nichrome wire have excellent corrosion resistance.

The Type C Nichrome wire is very useful in applications where a high resistance is required within a limited space. In heating and technical applications, the Type A heater wire is most commonly used. The Type A and Type C Nichrome wires are both offered in large or small spool sizes, coils, or straightened and cut to length..
