Zirconia ZrO2 Ceramic Knife Blade/Ceramic Cutting Blade

Zirconia ZrO2 Ceramic Knife Blade/Ceramic Cutting Blade

UNIPRETEC has been in the research and production of zirconia ceramic cutters / blades for many years, today our ceramic blades / cutters have been applied for industrial applications in the world.

Zirconia ceramic cutters / blades are made of Zirconium Oxide (ZrO2). ZrO2 is very hard, it ranks 9 on the Mohs Scale of Mineral Hardness, compared to 6 to 6.5 for hardened steel, and 10 for diamond, so they can only be ground using diamond wheels. They are nonrust, nonconductive and nonmagnetic. Their chemical inertness to both acids and alkalis and their ability to retain a cutting edge up to ten times longer than metal cutters / blades.

Our ceramic cutters / blades can be made into different shapes and sizes according to customer's design, their application is broad, far now, they have been used for cutting capsules, packaging, rubber, fiber, plastics, film, foil, mat board as well as other products.
