Resistance Wire Specification Sheet

Ordering Information

When specifying resistance wire, it is important to consider all aspects of the application and of the wire. For example, if the application is on a conductive surface, wire type RWF should not be chosen. Also, if the application requires constant temperatures of 350°F (176°C), then alloy J should not be chosen. Call your local distributor or BriskHeat direct for application assistance.
