Metal seal

O-ringcopperceramic

INNOVACERA offers customers a wide variety of vacuum-tight, hermetically sealed ceramic-to-metal, glass-ceramic, and glass-to-metal components. Ceramic-to-metal sealing products not only have the characteristics of ceramic high temperature resistance and corrosion resistance, but also have the strength and toughness of metal. They are widely used in electronic aerospace, medical industry, and other applications. The best customer service and efficient solution provided is INNOVACERA's commitment. - Housing Material: NiFe Alloys & NiFeCO (Kovar), 300 & 400 Series SST, Cu and Cu Alloys, Inconel, 42, 46, 49 Alloys - Insulator: 94%-99% Al2O3, AlN, BeO - Conductor: Kovar, Copper Cored Kovar, 52 Alloy, Inconel, Stainless Steels - Hermetic Seal Properties: - Hermeticity: up to 1×10^-9 atm cc/sec He - Working Temperature > 500°C depending on materials and geometry - Insulation Resistance: Typically exceeds 1 GΩ @ 100 VDC - Ceramic-to-Metal Sealing Features: - High Abrasion Resistance - High Mechanical Strength - Pressures over 10,000 PSI - High Temperature Usage - Low Dielectric Loss - Mass Spectrometer Leak Tested - High Chemical Stability - Ceramic-to-Metal Welding Process: - Cleaning - Pasting - Metallizing - Nickel Plating - Mounting - Welding - Inspection & Packing - Ceramic-to-Metal Sealing Applications: - Relay Insulators - Capacitor - Magnetrons - Travelling Wave Tube - X-ray Tube Components - Electrosurgical Instrumentation - Implantable Packages and Feedthroughs - Gas Detectors - Microscopes (TEM, SEM) - High Voltage Feedthroughs - High-temperature Feedthroughs - RF Feedthroughs - Optoelectronics and Power Tube - Laser Tubes - Thyristors - Diodes - Technical Specifications / Features: - Vacuum-tight, hermetically sealed construction - High temperature resistance (ceramic) - Corrosion resistance (ceramic) - Strength and toughness (metal) - Materials: NiFe Alloys (Kovar), Stainless Steel, Copper Alloys, Inconel, Al2O3, AlN, BeO - Hermeticity up to 1×10^-9 atm cc/sec He - Working temperature > 500°C - Insulation resistance > 1 GΩ @ 100 VDC - High mechanical strength and abrasion resistance - Pressure resistance over 10,000 PSI - Low dielectric loss - Leak tested by mass spectrometer - High chemical stability
