Starting from the rigorous testing of the wire for all crucial factors, balls are produced in specifically designed machines called Headder, Flasher, Grinder and Lapper. Heat treatment is one of the most important operations that give required strength & hardness to the balls. Heat treatment makes the balls tough and wear resistant. Different materials can be used and are outlined below, if you cannot find what you are looking for please feel free to contact us directly.

Ceramic Silicon Nitride (Si3N4) Series Balls
Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temeratures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitirde is non-porous, non-magentic, non corrosive...Learn More »

Ceramic Alumina Oxide (Al2O3) Series Balls
Alumina Oxide (Al2O3) Ceramic Balls are resistant to most corrive materials except for hydrochloric and hydroflouric acids or strong alkaline solutions. Alumina Oxide is non-porous, lighter than steel and, in ball form, harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable...Learn More »

Ceramic Zirconia Oxide (ZrO2) Series Balls
Zirconia is inert to corrosive materials, with the exception of hydrofloric acid and hot concentrated sulfuric acid. Zirconia is lighter than steel, non-magentic and has a maximum useful temperature of 1800F or 968C...Learn More »

S-2 Tool Steel Rock Bit Series Balls
S-2 Rock Bit Balls are most frequently used in oil field equipment and offshore drilling operations. Rock Bit balls provide good service in withstanding the abrasion of pulverized rock and mud slurries. They are capable of providing the toughness and strength necessary for shock loads and harsh environments.Learn More »
