Tungsten Plate
Tungsten mill products from tungsten plate, tungsten sheet, and tungsten foil with many options on width, length, and thickness. Pure Tungsten flat-rolled products are fabricated from pressed and sintered powder metallurgy ingot. Tungsten ingots are first forged into block blank and then rolled to tungsten plate, tungsten sheet, and tungsten foil. We provide Tungsten plates with purity W≥99.95%, widely used in ion implantation, sputtering, coating, medical CT, electronics, and vacuum equipment.
Purity: W>99.95% (99.999% can also be achieved if special demanded)
Density: >19.15g/cc
Surface: Hot-rolled surface, cold-rolled surface, polished surface
Flatness: <2%
