Product Introduction of Blue Zirconia Ceramic Punches
Blue zirconia ceramic punches are precision-machined components made from high-performance ceramic materials primarily composed of zirconium dioxide (ZrO₂). Zirconia ceramics are typically white at room temperature, containing trace amounts of hafnium dioxide (HfO₂) and the stabilizer yttrium oxide (Y₂O₃). Through special processes, they can be made to appear blue. This material possesses excellent properties such as high hardness (Mohs hardness 8.5-9, close to diamond), high toughness (fracture toughness above 8 MPa·m¹/²), and high bending strength.
