Why Is Material Selection So Important?<\/h2>\n\n\n\n

The performance of a ceramic-to-metal assembly depends not only on its design, but also on the combination of materials used to manufacture it.<\/p>\n\n\n\n

Ceramic materials, metals, and brazing alloys all contribute to the final performance of the assembly, influencing electrical insulation, mechanical strength, hermeticity, corrosion resistance, thermal stability, biocompatibility, and long-term reliability.<\/p>\n\n\n\n

Rather than recommending a single material, SCT helps customers identify the combination of ceramic, metal and brazing alloy best suited to the technical, environmental and manufacturing requirements of each application.<\/em><\/p>\n<\/div>\n\n\n\n

Alumina: The Foundation of Technical Ceramics<\/h2>\n\n\n\n

Alumina is one of the world’s most widely used technical ceramics and forms the foundation of many ceramic-to-metal assemblies.<\/p>\n\n\n\n

Its unique combination of electrical insulation, mechanical strength, corrosion resistance, thermal stability, and compatibility with metallization and brazing processes makes it particularly well suited for demanding medical and industrial applications.<\/p>\n\n\n\n

SCT’s proprietary ALUCER\u00ae alumina family includes multiple alumina formulations optimized for different electrical, mechanical, and manufacturing requirements.<\/strong><\/p>\n<\/div>\n\n\n\n
