Product detail
Aluminium Nitride (AlN) is a highly desirable material for applications that demand high thermal conductivity and electrical insulation properties. This makes it an ideal choice for thermal management and electrical applications. In the semiconductor industry, AlN is frequently used as a substitute for Beryllium Oxide (BeO) due to its non-toxic nature when machined. Furthermore, Aluminium Nitride ceramics exhibits a coefficient of thermal expansion and electrical insulation properties that closely resemble those of Silicon wafer material. As a result, it proves to be a valuable material for electronics applications where high temperatures and efficient heat dissipation are often challenging factors.
Mascera is able to provide aluminum nitride ceramics in custom size and design, we can provide ceramic plates, ceramic rods, ceramic tubes, ceramic rings and other irregular shapes. We have capability to machine the parts to very precise tolerances with a fine grinding or polishing surface.
