Compared to alumina ceramics, ZTA products offer higher wear resistance, flexibility, chemical stability, and corrosion resistance. ZTA products are highly suitable for use in harsher environments due to their high temperature resistance, hardness, insulation properties, wear resistance, crack resistance, and high pressure tolerance. We can manufacture and process various precision ceramic structural components according to customer requirements.
