Small size ceramic al2o3 97% alumina ceramic electric insulator
parts with holes
Alumina, also known as Aluminum Oxide, is a hard wearing advanced
technical ceramic material frequently used in a wide variety of
industrial applications. Once fired and sintered, it can only be
machined using diamond-grinding methods. It features high hardness
and wear resistance, low erosion levels, high temperature
resistance, corrosion resistance, and bioinertness. Additionally,
it can be highly polished making it useful for precision sealing
applications like pumps and
pistons.
Alumina is an excellent high temperature ceramic material due to
its high temperature stability. It is the most commonly used type
of advanced ceramic and is available in purities ranging from 95 –
99.9%. Precision Ceramics has access to many different types of
Alumina including: injection molded, die pressed, isosostatically
pressed, slip cast, and extruded.
