Alumina ceramics are among the most common advanced ceramic丨 materials, widely used in many industries such as electronics, medical devices, and machinery.
Alumina ceramics can be classified into several application grades based on their alumina purity, with 95% and 99% alumina being the most common, possessing excellent physical properties.
GORGEOUS CERAMICS (GGS) can process and manufacture ceramic products with complex shapes and small packages that have high precision, high reliability and high wear resistance for customers.
