Zirconium AG ST 89-71-14

Zirconium is a new line of zirconium oxide materials designed for use in cad / cam technology. Zirconium products have SFDA, ISO13485, CE and FDA certificates. Due to the two-stage production process: axial pressing and "cold" isostatic pressing, zirconium zirconium discs are characterized by a homogeneous structure, which is an element characteristic of high-quality zirconium discs.
