Alumina-Ceramic Balls
These spherical, dry-pressed alumina-ceramic balls are designed for mechanical devices that provide rotary or linear motion, such as check and ball valves and bearings. Because alumina is resistant to high temperatures and most corrosive substances, the balls are suitable for use in extremely harsh environments. In addition, balls manufactured with alumina are stiffer, lighter, smoother, harder and more electrically resistant than comparable steel products, providing increased versatility at a more cost-effective price.
