Product Description

TZP ceramic blade is made from Yttria partially stabilized zirconia, Possessed with extreme sharpness and hardness, superior resistance to corrosion and abrasion, low friction coefficient make zirconia ceramic particularly effective in slitting operations, And blade life can be more than 100 times that of conventional steel blade which greatly decrease the frequeny and time of blade replacement, also these properties ensure the precision cut and better looking edges. All the characteristics of Zirconia make it an attractive material in many applications include:
1. Superb Corrosion Resistance;
2. Antimagnetic;
3. High Electrical Insulation Properties;
4. High-shock Applications.
At present, it is mainly used in food processing industry, textile industry, rubber and plastic cutting, automobile manufacturing industry and medical field.
