Zirconia Ceramic Knife Core Characteristics
Advanced Material Optimized for Food/Medical/Secondary Battery Clean Processes
- Zero Metal Ion Elution & Perfect Corrosion Resistance: It does not corrode in moisture or chemicals, and no iron powder or metal ions are mixed during cutting, making it the safest for processing food and medical materials.
- Non-magnetic and Electrical Insulation: Not affected by magnetism and non-conductive, it innovatively reduces the defect rate when slitting electronic components and secondary battery separators.
- Overwhelming Ultra-high Hardness (HV 1200~1300): Much harder than general heat-treated steel, blade wear is extremely low when cutting resin, film, non-woven fabric, etc., boasting an overwhelming lifespan.
