In our offer you can find yttria and magnesia stabilised zirconia, which reveal exceptionally high fracture toughness, high bending strength and thermal shock resistance, and are characterized by high polishability.
Yttria and magnesia stabilised zirconia are used for the machines and devices parts production subject to rapid wear, i.e. positioning pins in welding processes in the automotive industry, plungers for pumps, valve balls, homogenizer elements, nozzles and guides.
