中央部に円形の貫通穴を有するアルミナセラミック

The middle circular through-hole alumina ceramic is a special ceramic component made of high-purity alumina (Al ₂ O ∝) material, which is precision formed, high-temperature sintered, and precision processed. Its core feature is the central circular through-hole structure, which combines excellent mechanical strength, high temperature resistance, corrosion resistance, insulation performance, and high dimensional stability, making it an ideal choice for key functional components in industrial equipment.
