Product Description

Alumina ceramic is the most mature engineering ceramic, offering excellent electrical insulation properties combined with high hardness and superior wear resistance. While it has relatively lower strength and fracture toughness, its thermal stability makes it ideal for high-temperature applications. The material typically appears white but may also be pink or ivory depending on sintering additives or raw material impurities.

Key Features & Advantages
  • High hardness: Exceptional surface durability for demanding applications
  • High heat resistance: Excellent thermal stability for extreme temperature environments
  • Superior wear resistance: Ideal choice for alumina wear parts and components
  • High electrical resistivity: Excellent insulating properties for electrical applications
  • Exceptional corrosion resistance: Insoluble in water and resistant to strong acids and alkaline solutions
