AI Overview
Alumina (
) ceramic relays utilize high-purity alumina housings to provide superior electrical insulation, high-voltage resistance (up to
), and arc suppression, often featuring hermetic sealing for vacuum components. These components, such as casing, envelopes, and terminals, ensure durability in harsh, high-temperature, and high-voltage conditions.

What is alumina ceramic used for?
Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.Nov 14, 2025

Which is harder, alumina ceramic or hardened tool steel?
The hardness of alumina ceramics is nearly three times that of stainless steel; silicon carbide is more than four times harder than stainless steel. This extreme hardness is one of many unique properties that makes Fine Ceramics "super materials" for modern technology.
