Tungsten Rhenium 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.

WR3 and WR25(W-3Re and W-25Re)

They are used as  thermal couple wire, WR3 as positive lead wire; WR25as negative lead wire;

WR5 and WR26 (W-5Re and W-26Re)

They are used as  thermal couple wire, WR5 as positive lead wire; WR26 as negative lead wire;

WR5 and WR20 (W-5Re and W-20Re)

They are used as  thermal couple wire, WR5 as positive lead wire; WR20 as negative lead wire;

WR20, WR25 and WR26 (W-20Re, W-25Re and W-26Re)

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