Our solid Tungsten crystal bars (≥99.95%) were made by thermo-reduction of WF6 and H2, giving them a unique crystalline structure.This production method has nearly disappeared, it explains the rare and shiny metallic surface - a sintered bar can never have this "bright" surface. It makes the material very close to its theoretical density.

From the collector:

It took me a few years to collect all these beautiful Tungsten crystal bars. When my friends visited my lab, they were shocked by those shiny bars. We only have about 500 grams now, and no more in the future after these are sold out. Only for metal lovers!
