Zirconia vs. Macor: Impact Resistance Comparison

FAQS

What is Magnesium-Stabilized Zirconia (Mg-PSZ)?

Magnesium-Stabilized Zirconia is a type of zirconia ceramic stabilized with magnesium oxide (MgO). It offers high toughness, wear resistance, and thermal stability, making it suitable for mechanical components, cutting tools, and high-temperature applications.

Can it process complex, irregularly shaped structures?

Yes, including grooves, steps, holes, thin walls, cylinders, and pipes.

What is the lead time for Mg-Stabilized Zirconia parts?

Standard parts: 7–15 days; complex parts: 15–30 days.

Macor is a machinable glass-ceramic made from fluorophlogopite mica crystals embedded in a borosilicate glass matrix. This composition gives it a rare
combination of metal-like machinability, excellent electrical insulation, low thermal conductivity, and stability up to 1000°C (no load) while maintaining very tight tolerances.
