Zirconium Valve Balls

Valve Balls

TongBall zirconia ceramic valve balls integrate high hardness, fracture toughness and wear resistance. Nanostructured powder treatment and high temperature sintering form fine and homogeneous microstructures that provide superior mechanical strength and low friction, chemically inert surfaces that outperform alumina in demanding mechanical applications involving aggressive media, abrasive particles and high temperatures.
