Specifications of Tungsten Rhenium Wire

Tungsten rhenium wire main specifications are : W-Re1%，W-Re3%，W-Re5%，W-20%Re,W-25%RW-26%Re.

Positive thermo element:

The positive thermo element for the W3RE/W25RE combination have a nominal composition of 97 % tungsten and 3 % rhenium.
The positive thermo element for the W5RE/W26RE combination have a nominal composition of 95 % tungsten and 5 % rhenium.
The positive thermo element is doped by the addition of potassium, silicon, and aluminum compounds or otherwise, Stabilized by the addition of volatile substances that promote desirable grain structure and workability and maintain ductility after high temperature use.

Negative thermo element:

The negative thermo element for the W3RE/W25RE combination have a nominal composition of 75 % tungsten and 25 % rhenium.
The negative thermo element for the W5RE/W26RE combination have a nominal composition of 74 % tungsten and 26 % rhenium.
