Various shapes of alumina ceramic structural components

Aluminum oxide ceramic structural components are high-performance ceramic materials mainly composed of high-purity aluminum oxide (Al ₂ O3), which have high hardness, high wear resistance, good electrical insulation, excellent chemical stability, and high temperature stability. According to the different contents of alumina, it can be divided into 75%, 85%, 95%, and 99% alumina ceramics. These structural components are usually manufactured using advanced molding processes (such as dry pressing, grouting, hot isostatic pressing, etc.) and sintering techniques, which can meet the strict requirements of various industrial applications.
