The description of zirconia ceramic parts
Zirconia ceramic parts are made of zirconium oxide ceramics which is a kind of strongest technical ceramic material with exceptional strength, high toughness, and superb reliability. These outstanding characteristics result in excellent resistance to wear and corrosion.

We have been offering a selection of partially stabilized zirconia, including Y-TZP( yttria-stabilized), MSZ ( magnesia stabilized ), CSZ- (ceria stabilized). Each stabilized zirconia provides unique and specific properties that meet the demands of extreme applications found in many industries.

With our production capability through CNC, precision grinding machines,  we are able to provide many different levels of precision zirconia ceramic parts to meet customers' high precision assembly needs.
