For over 100 years, SCT\u2019s commitment to quality has been rooted in the ceramics materials we develop and use. We use proven manufacturing processes to develop our own advanced ceramic formula, ALUCER\u00ae.

Technical ceramics are an ideal solution where higher strength, lighter materials and longer product lifespans are required. The formulas can be customized to increase a product\u2019s performance in a wide range of applications and extreme conditions.&nbsp;&nbsp;Throughout the years, SCT has developed over 100 different formulations of our alumina ceramic ALUCER\u00ae to meet the demands of the high-reliability markets we serve.&nbsp;<\/p>\n\n\n\n<p>SCT has perfected the art of joining ceramic to metal, in a process known as brazing. Brazing produces a hermetic seal between the ceramic and the metal sub-components, a major criterion for assemblies&nbsp;operating in extreme environments. SCT\u2019s brazing occurs at temperatures capable of reaching up to 1,600\u00b0C (2,912\u00b0F).<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>Due to their many technical advantages, advanced ceramics are often used in lieu of competing materials, such as glass or plastic.
