Description

Tungsten-rhenium wire is tungsten rhenium alloy wire, made by metal rhenium powder and tungsten powder. Through production processes, such as forging etc. with powder metallurgy technology.

The wires is solid, round, smooth and be free of weld joints, slivers, kinks, pits or nicks exceeding 5 % of diameter . Tungsten rhenium wire surface is uniformly clean and free of discoloration. The thermo elements is heat treated to provide the specified ductility.

Tungsten-rhenium wire is the most common material used to produce heaters for dispenser cathodes. Performance variation may be attributable to a range of factors, including cold work and rhenium content variety.
