Alumina

Alumina

Alumina (aluminium oxide, Al2O3) can be termed as an all-rounder in the field of ceramics. Its anti abrasive, anti corrosive & excellent dielectric properties, High performance/Price ratio and lightweight characteristic makes it an excellent material of choice for use in various industries. The alumina ceramics can be graded on a scale in terms of alumina content in the alloy typically ranging from 85% to as high as 99.8%. Each grade finds suitable usage in one or more particular application(s).

Alumina alloys with different % of alumina content can be formulated and explored for the high performance requirements of more challenging applications. CUMI has its imprint on the whole range of alumina materials which are used by our customers in various industries.
