Metallized Alumina Ceramic Ring
Mo/Mn metallized and Ni, Cu, Ag or Au plated rings ready to braze.
- MaterialAlumina (Al2O3)
- SizeCustom
- ColorWhite + metal
Electrical Power Equipment
Hermetic and standoff insulation that has to braze to metal and hold vacuum.
Industry Pain Points
- A ceramic to metal joint has to be gas tight and survive thermal cycling.
- Creepage distance and dielectric strength are set by the insulator, not the housing.
- Plating has to be repeatable or the braze will not wet the surface.
What Buyers Ask For
- Mo/Mn metallizing at 25 plus or minus 10um with 2 to 10um nickel over it.
- Pin pull strength averaging 4200 kgf/cm2 at a 3.0mm pin.
- Ni, Cu, Ag or Au plating, or printed Ag, depending on the joining method.
