Zirconia Balls

Uses:
High – precision zirconia balls are available in many sizes.  Zirconia balls are most commonly used as check valves in flow control applications.  When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes “transformation toughening” which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.  online contact form

Corrosion Resistance:
Zirconia balls also feature resistance to abrasion and corrosion and are chemically inert to molten metals, organic solvents, caustics, and most acids.  In addition, zirconia balls maintain high strength at temperatures up to 982ºC (1800 ºF).  Some sizes are available from stock; others may be manufactured to your specifications.
