tungsten rhenium wire

WR31, higher non-sag property WR30, WR250 for thermal couple wire WR50, WR260 for thermal couple wire

 WR31 (W-3Re)

It has a special non-sag property and many applications: heaters for various electronic tubes or small lamps. It also is the ideal material for probe pin because of its hardness.

WR30 and WR250 (W-3Re and W-25Re)

They are used as  thermal couple wire, WR30 as positive lead wire; WR250 as negative lead wire;

WR50 and WR260 (W-5Re and W-26Re)

They are used as  thermal couple wire, WR50 as positive lead wire; WR260 as negative lead wire;

WR200, WR250 and WR260 (W-20Re, W-25Re and W-26Re)

They are all used as tie in the process of sapphire substrate producing.
