Ceramic to Metal Assemblies (CMA)
Alberox Products, a division of Morgan Advanced Ceramics, can integrate ceramics, alloys and brazing capabilities; our application engineers can provide you complete assemblies, fully tested and with total materials
traceability.
CMA Benefits versus Glass to Metal Seals
- More stable at high temperatures
- Better electrical properties (better insulators)
- More durable (better impact and thermal shock resistance)
- Mechanically stronger
Ceramic Types
- Polycrystalline Alumnia (94% - 99.9%)
- AlN
- Sapphire
- Ruby
Typical Braze Alloys
- Copper and its Alloys
- Gold and its Alloys
- Silver and its Alloys
- Nickel Alloys
- Others
Typical Metals Alloys
- Copper and Copper alloys (CuNi)
- Nickel and Ni Alloys (Monel, Alumel)
- NiFe alloys and NiFeCo (Kovar)
- Molybdenum, Niobium, Tungsten, Tantalum
- Platinum, Titanium
- 400 Series SST (410, 430)
- 300 Series SST (304, 316, 321) & Inconels
Key information to assist us with your design
- What is the atmosphere (pressure, corrosive, temp, vacuum, processing temp for next level ass., etc)?
- What part of the assembly is subjected to this atmosphere?
- What is the application?
- What are your annual requirements (actual and potential)?
- What is your voltage requirement?
- Do you have space constraints?
- What materials are required (ceramic, metal, and braze)?
- What materials cannot be used (ceramic, metal, and braze)?
- Are you open to material suggestions (ceramic, metal, and braze)?
- Are there hermeticity requirements?
- Are there thermal cycling requirements?
- Are there size restrictions?
- What dimensions, if any, have design flexibility?
- Will there be further processing done? If so, what?
- Are there special plating requirements?
- What are your delivery requirements?
- Do you have cost targets?
