Sapphire balls offer wear, heat resistance.

Meller Sapphire and Ruby Balls feature Moh 9 hardness, are impervious to most chemicals, solvents and detergents, and have a 2,000 C melting point. They feature high wear and chemical resistance and can withstand thermal and environmental shock. Suitable for a range of applications because of their durability and stability, they have surface finishes of 20-10 scratch-dig or better, and can be drilled and precision-ground into plano-convex lenses, if required. Available in 42" and metric sizes from 0.1 mm to 0.5" diameter, the sapphire and ruby balls have a 0.2 coefficient of friction and a refraction index of 1.76 microns at 20 C. Applications include ball check valves, scanners, ball and roller bearings, gauge, probe, stylus tips, chemical and medical valves and fiber optic and endoscope lens systems.
