Alumina ceramic substrates for the automotive industry

Alumina ceramics is a ceramic material with a-Al2O3 as the main crystalline phase. Because of its high melting point, high hardness, heat resistance, corrosion resistance, and electrical insulation characteristics, it can be used under harsher conditions. Alumina ceramics have competitive prices and mature production technology. It is currently one of the ceramic materials with the largest output and the widest application range. It is mainly used in the fields of cutting tools, wear-resistant parts, and bio-ceramics. In addition, it is also widely used in energy, aerospace, chemical, chemical, and electronic fields. In particular, 95% and 99% alumina ceramic components, whether in structural ceramics or electronic ceramics, are some of the most widely used and most used ceramic materials.Get more news about Alumina Ceramic Substrate,you can vist our website!

Such Alumina ceramic substrates now are widely used in the automotive industry, especially the large ceramic substrate. Innovacera are specializing in alumina ceramic substrates, the max size of AL2O3 ceramic substrates Innovacera made is 380*200*1 mm (0.8 mm and 0.635 mm thickness are also available). The substrates are part of a specific brazing process, used as spacers during thermal treatment.
Valley can also produce round substrates, 50mm - 150mm in diameter meeting SEMI M1 STD specifications with flatnesses as good as .001 TIR. Depending on substrate thickness and size, Valley Design can hold flatness to .1 mil over any square inch area, and surface finish can be made as smooth as 2µ" Ra, or controlled to any finish required. For lasered 96% Alumina parts, Valley Design has developed a process for laser slag removal as well as edge rounding. On substrates and laser holes, this process can remove slag from one or both sides and chamfer square or round holes without the risks associated with blasting techniques.
