Alumina Bonded Silicon Carbide
ALTRON™ Alumina Bonded Silicon Carbide is designed for exceptional wear and corrosion resistance at a reasonable price. It can be formed into a variety of relatively complex shapes with good tolerance control, without incurring traditional hard tooling setup charges.
ADVANTAGES OF ALTRON™
- Abrasion resistance approaches that of much more expensive, fully dense, advanced ceramics
- Retains the outstanding thermal shock resistance of less dense refractory grade materials
- Offers superior oxidation resistance at elevated temperatures
