Frequently Asked Questions (FAQ)

Q1: Why choose Yttria-Stabilized Zirconia (Y-TZP) balls over alumina ceramic balls?

A: Y-TZP zirconia balls offer much higher fracture toughness (8–10 MPa·m¹/²) and flexural strength compared to standard alumina ceramics. This high toughness prevents cracking, chipping, or catastrophic failure under heavy mechanical loads, intense pressure, or violent fluid impacts in check valves and bearings.

Q2: What precision grades and surface finishes can you supply for zirconia valve balls?

A: We manufacture precision zirconia ceramic balls ranging from Grade 5 (G5) to Grade 25 (G25). Our optical-grade polishing process achieves sphericity within 0.00013 mm and surface roughness down to Ra < 0.005 µm, ensuring a mirror-smooth finish for zero-leakage sealing in severe-service fluid valves.

Q3: Are customized sizes or sample kits available for engineering testing?

A: Yes, we fully support custom manufacturing based on your specific engineering drawings and tolerance requirements. We also provide sample evaluation kits for R&D testing and material verification prior to full production runs.
