Wire

Wire

Wire in a wide range of alloys optimized for use in, for example, resistance, high-temperature and conductive applications.

Round and flat resistance heating wire and resistance wire with bright annealed or oxidized surface, depending on size. Round resistance wire sizes up to 0.40 mm (0.0157 inch) are available with insulation and coating
