Zirconia Alumina

Zirconia Alumina is the most resistant, toughest type of fused alumina available. Depending upon the individual type of material, this fused alumina has a zirconium oxide content of 25% or 40%. In effect, the material is extremely durable compared to all other types of fused alumina. This makes it of particular interest as a component in especially long-lasting tools.
