How hard is alumina ceramic?

2024-10-25
Latest company news about How hard is alumina ceramic?

Hardness Comparison

  • Alumina Ceramics: The hardness of alumina ceramics is nearly three times that of stainless steel, making them exceptionally wear-resistant and suitable for demanding applications.
  • Silicon Carbide: Even harder than alumina, silicon carbide is more than four times harder than stainless steel, providing superior resistance to abrasion and wear.

Unique Properties

This extreme hardness, along with other characteristics such as high thermal stability, electrical insulation, and chemical resistance, contributes to the classification of Fine Ceramics as "super materials." These properties make alumina and silicon carbide essential in modern technology applications, including electronics, aerospace, and industrial machinery.
