High Hardness/High Strength Ceramic Utility Knife Blade

Ceramic Cutters / Cutting Blades are usually made out of zirconium oxide (ZrO2). These cutters / ceramic blades can only be ground using diamond because of their very high hardness. This material ranks 8.5 on the Mohs Scale of Mineral Hardness, compared to 6 to 6.5 for hardened steel, and 10 for diamond, giving a very hard edge that rarely needs sharpening.

Ceramic Cutters / Cutting Blades do not rust.They are also nonconductive and nonmagnetic, which can be useful for bomb disposal operations. They have chemical inertness to both acids and alkalis and also have ability to retain a cutting edge up to ten times longer than forged metal knives.

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.
