Re: Sapphire Balls

Sapphire balls are high-precision spherical components fabricated from high-purity single-crystal sapphire (Al₂O₃), combining exceptional hardness, dimensional accuracy, and chemical stability in a single, wear-resistant form. Ranked 9 on the Mohs hardness scale—second only to diamond—these balls deliver superior durability and long service life in applications where conventional steel, ceramic, or glass spheres fail under wear, corrosion, or extreme temperatures.
