Tungsten Nickel Wool

Epoxy Molding Compounds (EM-200)

Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.

Tungsten Rhenium Alloy

W-Re alloy is an alloy of tungsten and rhenium. One type of the alloy is low rhenium alloy with rhenium under 5%, the other is high rhenium alloy with rhenium of 20% ~ 30%. Rhenium is a rare metal, scarce and expensive.

Tungsten Nickel Iron Powder (WNiFe)

Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.
