Ceramic Ball
Best quality Ceramic balls
Ceramic Ball Details
We manufacture Ceramic Balls in sizes ranging from 0.25 mm to 8.0 mm in diameter.
The most common ceramic ball material is alumina oxide Al2O3.
Alumina oxide balls resist corrosion and abrasion extremely well and maintain dimensional stability at temperatures up to 1734ºC (3180 ºF). Al2O3 balls may be used in many corrosive chemicals, salts and acids where a material that resists oxidation is required.
Applications where alumina oxide balls are used include chemical pumps, down-hole pumps, valves, bearings, gages, flowmeters, etc.
In terms of visual appearance, our ceramic Ball can have a surface finish of No Scratch/Dig at 30x Magnification level (depending on the diameter of the Ceramic ball lens).
Each and every Ceramic ball is checked 100% for Size, Accuracy, Polish level and Cleaning before delivery.
All Ceramic Ball products are cleaned and packed in Class 100 clean room area.
