Q: Do ceramic fasteners provide strength? A: The answer to your question is both yes and no. They provide decent tensile strength similar to some stainless steels(Aluminia bolts has a tensile strength of 30 ksi and Zirconia screws 75 ksi), however they don’t have any yield strength. Due to the … Continue reading

Q: Why does Zirconia cost more than Alumina? A: 1) Raw material cost: Aluminia is far more abundant, whereas Yttrium oxide which is a stabilizer for Zirconia ceramic, is a rare earth element. 2) Shaping costs: Due to its higher density it takes approximately 10x longer to grind down and shape … Continue reading
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 … Continue reading
