FAQ

Q.What is the purpose of metallization?

A.It enables strong brazing/soldering of ceramics to metals, creating reliable hermetic seals and electrical connections in high-vacuum or high-voltage applications.

Q.Why use Molybdenum-Manganese (Mo/Mn) as the base coating?

A.Mo/Mn provides excellent adhesion to alumina through high-temperature sintering, ensuring high bond strength and reliability.

Q. Do you offer custom metallized ceramics?

A.Yes, we produce fully customized components based on your drawings, samples, or specific requirements.
