Frequently Asked Questions

What are metallized ceramics?

Metallized ceramics are ceramic components with a metal layer bonded to their surface, enabling reliable electrical connections and hermetic seals in vacuum and high-voltage applications.

Can you customize ceramic substrates?

Yes, we offer laser cutting, scribing, and metallization services for Al2O3, AlN, and Si3N4 substrates to meet your exact specifications.

Are your grinder burrs food-safe?

Absolutely. All our ceramic grinding components are made from high-purity, non-toxic alumina and are safe for food contact applications.

What industries do you serve?

We support electronics, energy, automotive, medical, consumer appliances, and industrial manufacturing sectors worldwide.
