Product Details
Y-ZR (3Y series)
Y-ZR (3Y series) is a structural member of yttrium stabilized zirconia, According to customer's demand, we can precisely process structural parts with high temperature resistance and corrosion resistance. High wear resistance and other advantages, can be used stably in complex working conditions.
1. Characteristics and advantages of product materials
• Excellent corrosion resistance, suitable for all kinds of acid and alkali conditions;
• Super hardness and fracture toughness of ceramic materials, products are not easy to wear;
• Neutral physicochemical index, no pollution to the ground material;
• Complex 3D modeling surface, five-axis five-joined surface.
2. Application
Suitable for valve core, plunger, mold, cutter, shaft, bearing, liner, sealing ring, etc.
