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 K should not be chosen. Call your local distributor or BriskHeat direct for application assistance.

Resistance Wire
What is a multi-stranded resistance wire?
Several smaller wires of various metals like nickel, aluminum, chrome, and copper are combined to make one wire.
Why multi-stranded?
Wires are more flexible and durable and exact heater specifications are better met.
Can I buy it by itself?
Yes, available lengths are 500 feet (152 meters) and 1,000 feet (304 meters). Contact BriskHeat to determine the proper part number.
