As the technology's fast progress, conventional glass-to-metal seals can't meet the high-tech requests, so ceramic-to-metal assembly represents one of solutions, ceramic-to-metal assembly have a number of advantages resulted in a more robust, durable hermetic seal.
Shanghai Fine-Boon as the professional ceramic components manufacturer and brazing company, we worked with our metal machining partner closely, so we can make various ceramic to metal seals, we use our own-produced metalized alumina and outsourced metal parts for brazing . The ceramics are with high purity alumina with metallization treatment (such as Mo-Mn), then nickel plated for next brazing purpose. Also Sapphire and ruby are can be sealed with metal parts together, used for windows and viewports.
Shanghai Fine-Boon is engaged in ceramic to metal assembly in recent year with our customers' support. Now we get rich experiences, extensive knowledge and advanced equipments to make various ceramic to metal seals and assemblies gradually. We collaborate closely with our metal machining partners, so we can always provide one鈥搒top service from individual machined metal parts or ceramic parts to ceramic-to-metal brazed assemblies.
Whether your demand for individual ceramic parts or ceramic to metal seals is for sample or mass production, we will be gald to provide professional service for you. Our ceramic to metal seals get excellent performance in various harsh industrial environments.
