Zirconia Toughened Alumina (ZTA) ceramic composite is a unique ceramic material that combines high hardness, strength, wear, and corrosion resistance due to the presence of alumina, while still maintaining high fracture toughness due to the presence of zirconium oxide. They are very hard, have excellent mechanical properties, and high reliability, and are particularly suitable for challenging mechanical wear situations.
