Alumina ceramics are used in a number of applications as an alternative to industrial diamond, as they are far more affordable to produce.Machining of various kinds is made from Alumina, including insulators used in electrical systems and spacers used to reduce the deteriorative effect of friction between movable parts.

● The surface roughness of the alumina plunger can reach Ra0.2um.

●Can be used in environments up to 1650°C.

● Hardness up to 15.7Gpa, very wear-resistant.

● 99Alumina Ceramic has good thermal shock resistance, can withstand high temperature and acute cooling without damage.

●99 alumina ceramic parts have very high electrical insulation.

● High hardness and wear resistance, as well as compressive strength and other characteristics, widely used in electronic and electrical industries.

Alumina is an excellent high temperature ceramic material because of its high temperature stability. It is one of the most commonly used advanced ceramics.
