The most versatile ceramic is "alumina (Al₂O₃)."

A representative material of ceramic that is highly versatile and relatively inexpensive.

Alumina refers to aluminum oxide. Due to its high versatility and relatively low cost, it is the most commonly used representative material among ceramics. It has high electrical insulation properties and excels in hardness, compressive strength, wear resistance, and chemical resistance, making it widely used as a mechanical material. Our company primarily uses 99.5% alumina, but we also offer 96% depending on the application. Metallization processing is also possible for alumina substrates. Please contact us for more details. <Features> - A highly versatile material among ceramics - Widely used as a mechanical material due to its excellent hardness, compressive strength, wear resistance, and chemical resistance - High electrical insulation properties and relatively low cost - High heat resistance (approximately 1500°C) and relatively high thermal conductivity. However, it has a high thermal expansion coefficient and is weak against thermal shock.
