Ruby Balls contain a trace of chromium to produce its red color making it easier to see and handle. Defining properties include durability, hardness (measuring 9 on the Mohs scale), non-porosity, corrosion resistance and chemical resistance and high thermal conductivity.
Mechanical applications for precision ruby balls and hemispheres include: bearings, valves, pumps, flow meters, metrology instrumentation, medical devices, probes.
Optical applications for precision ruby balls and hemispheres include: lenses, fiber optics, bar code readers, medical devices.
