Ruby material is grown in the factory by melting ultra-pure Al2O3 at temperatures above 2000 deg. degrees Celsius to create a single crystal. This hard material can be polished to a very good surface finish.
We offer sapphire and ruby balls in a variety of sizes down to 0.15 mm in diameter.
Typical applications: fiber optic connectors, flow meters, rotameter, barcode readers, gemstone bearings. low friction number, high hardness, corrosion resistance, low coefficient of thermal expansion, high compressive strength, and performance that can meet the requirements of instrumentation bearings. High rotational accuracy, good sensitivity, long service life.
