Ceramic-Metal Compounds  Manufacturers, Traders, Suppliers

Metallized ceramic parts are ceramic parts that have a thin layer of metal deposited onto their surface using various techniques such as sputtering, electroplating, or vapor deposition. The metal layer acts as a bonding interface between the ceramic part and the filler metal, allowing for a strong and reliable bond to form during the brazing process.

• Nickel – Diffuses well with silver-based braze alloys
• Copper – Excellent wettability but requires plating with gold or nickel
• Kovar or Invar – Alloys match ceramics’ CTEs to minimize residual stress
• Tungsten or Moly-Manganese – Active metal brazes readily bond to these layers

Ceramic-to-metal assemblies combine the unique properties of ceramics and metals, creating components that excel in high-performance applications. Ceramics provide superior thermal resistance, electrical insulation, and corrosion resistance, while metals offer mechanical strength and ductility.
Advanced bonding techniques, such as brazing and metallization, ensure strong, reliable joints between ceramic and metal parts. These assemblies are used in industries like aerospace, electronics, and energy for applications including vacuum tubes, insulators, medical devices, and sensors.
