Alumina Balls

Alumina balls are high-purity spherical ceramic shapes available from Goodfellow in a range of sizes from 0.2mm to 25mm diameter. With high hardness, compressive strength and wear resistance, alumina ceramic is valued for applications where resistance to corrosion, abrasion and thermal shock are priorities. Example applications for alumina balls include ball bearings, valve seats, grinding media and milling media. With 28 size variations, Goodfellow's alumina balls offer flexibility for prototyping and small-scale manufacturing across diverse industries.
