Q: What advantages does Zirconia have over Alumina?

A:   Usually for most high temperature or electric insulator applications where ceramics are needed, alumina ceramic fasteners are the most popular choice due to their properties and relatively affordable price compared to zirconia fasteners. However sometimes the extreme properties of zirconia fasteners are needed which include:

• Higher material density provides greater wear and corrosion resistance
• Higher strength
• Higher temperature resistance
