A ball has a ground surface with tight tolerances, and may or may not be polished.
A sphere is a sintered ball which has a band around one diameter; a feature of the molding tool.
A typical quality test for such products is the Crush Test, where the tungsten ball is compressed to less than 50% of its original size. Most competitors' products would crush under such severe conditions, resulting in cracked products or even powder disintegration. Our balls can withstand AS MUCH AS 70% REDUCTION of their original dimension.
