Quick Material Selection Guide
Not sure which material fits your application? Here is a quick comparison:
High-Purity Alumina (95% - 99.8% Al2O3)
Offers high electrical insulation, excellent corrosion resistance, and extreme temperature tolerance. Best for semiconductor parts, laser cavities, and sensor housings.
Refractory Alumina (Around 85% Al2O3)
Features exceptional thermal shock resistance and is highly cost-efficient. Best for kiln furniture, furnace linings, and saggers.
Zirconia Toughened Alumina (ZTA)
Provides extreme toughness, high impact, and superior wear resistance. Best for grinding media, pump liners, and mining chokes.
