Alumina Ceramic Slicing Knife with Wear Resistance for Protos 70 80 Cigarette Making Machine

The knife is made from aluminum oxide (Al2O3), commonly known as alumina, which is one of the most cost-effective and widely used ceramic materials. Alumina starts as a powder that can be machined before firing, with post-firing processing requiring diamond tooling. Its high thermal conductivity and low thermal expansion provide excellent thermal shock resistance. Available in purity grades from 88% to 99.99%, alumina can be manufactured through various methods including pressing, extruding, slip casting, and injection molding, with zirconia-toughened alumina offering enhanced strength.

• Resistance to climate and aging
• Environmentally compatible disposal
• Excellent thermal shock resistance
• High wear resistance and hardness
• Effective electrical insulation
