Ceramic Balls

We are a reputed precision ceramic balls manufacturer and supplier in India. Ceramic Balls may be used at temperatures up to 1725 deg. C (3135 deg. F). They are extremely hard, abrasion resistant, and immune to all furnace atmospheres. Used for check valves where heat, corrosion and / or abrasion resistance is needed. Alumina Ceramic balls have good resistance to most corrosive media but they are not recommended for use in Hydrochloric or Hydrofluoric acids or strong alkaline solutions.
