Zirconia Toughened Alumina (ZTA)

Composite material of alumina and zirconia has excellent wear resistance
material_zta_main.jpg

Zirconia Toughened Alumina is a composite material made of alumina and zirconia. It has a hardness and bending strength higher than that of alumina, with a lower thermal expansion than zirconia, and is characterized by high thermal conductivity. Taking advantage of its high wear resistance, it is widely used for wear-resistant parts that require cooling, including crusher parts.

Important property :
Hardness
Flexural Strength
Coefficient of Thermal Expansion
Thermal Conductivity

Features

  1. High stiffness and outstanding wear resistance
    Stiffer than alumina with outstanding wear resistance equivalent to zirconia.
  2. High thermal conductivity and low thermal expansion
    Suppresses thermal deformation through thermal conductivity and low thermal expansion equivalent to alumina. Suitable for components requiring a cooling Mechanism.
  3. High strength and specific rigidity
    Approximately twice as strong as alumina and contributes to low-weight design through high specific rigidity.
