About Us

Midwest Tungsten Service sells tungsten, tungsten alloy, molybdenum, and tantalum in rod, wire, sheet, plate, and bar form. We custom machine parts of tungsten, molybdenum, tantalum, and their alloys. We manufacture resistance heated evaporation sources and materials for vacuum evaporation (vacuum metallizing). These sources include tungsten filaments and boats, molybdenum filaments and boats, and tantalum boats. Evaporation materials include aluminum, copper, nickel, nichrome, tin, silver, and gold. We also make electron and ion beam filaments.
