Tungsten Carbide Slitting Knife HRC92-95 for Lithium Battery Electrode
This high-precision tungsten carbide slitting knife is specifically designed for the battery industry, offering exceptional wear resistance and machining precision. The outer circle precision is exceptionally high, with cutting edges undergoing rigorous testing and enlargement inspection.
Manufactured from cemented carbide powder through pressing, sintering, and fine grinding processes, this slitter features high wear resistance and anti-adhesion properties. It effectively solves common cutting issues including sticking knife, dust, burrs, knife back print, wavy edges, and color differences. Each blade undergoes 500x magnification inspection to ensure notch-free quality.
- Hard alloy tungsten steel material with superior wear resistance
- High machining accuracy with thickness precision up to 3 microns
- Extended service life with cutting length up to 20,000 meters
- Excellent blade consistency with minimal burrs and no curling
- Ideal for cutting lithium battery pole pieces, ceramic diaphragms, copper foil, and aluminum foil
- Available in upper and lower knife groups for complete cutting solutions
