Frequently Asked Questions

Q1: What are the primary advantages of Zirconia (ZrO2) ceramics? Zirconia offers exceptional wear resistance, high fracture toughness, and a thermal expansion coefficient similar to stainless steel, making it ideal for high-stress industrial applications.

Q2: Can I get customized dimensions for ceramic tubes? Yes, we support custom-made demands including specific materials, dimensions (OD 1-50mm, length 10-500mm), and complex designs like flanged or slotted tubes.

Q3: What level of precision can be achieved? Through precision grinding and CNC machining, we can achieve tolerances for OD, ID, and length as tight as 0.001mm.

Q4: Are samples available for quality testing? Yes, samples can be provided for evaluation. Please contact our team for availability regarding specific materials and sizes.

Q5: What is the lead time for shipping? For products currently in storage, items are typically shipped within 48 hours. Custom orders depend on the manufacturing complexity.

Q6: How does Zirconia handle high temperatures? Pure Zirconia can withstand temperatures up to 2400°C. However, the maximum service temperature for specific stabilized grades like Y-TZP is typically around 1000°C.
