Tungsten Filaments are used in a variety of applications. Globe Metal, Inc. specializes in recycling tungsten filaments. The two main industries that we recycle them for is the light bulb industry, and the vacuum metallizing industry. When shops are vacuum metallizing they use a tungsten filament to run a current into the water. After a while the filament evaporates and they then have to scrap them. That is where we come in. We send a truck to come pick up your scrap filaments and then pay you for them. It is as simple as them. To sell your tungsten filament scrap please call 1 (800) 700-6382 or sales@globemetal.com
