Lapped Polished Al2O3 Alumina Ceramic Wafer

Lapped Polished Al2O3 Alumina Ceramic Wafer

Alumina wafer, made from aluminium oxide (Al2O3), is a key material in advanced ceramics. It is valued for its high electrical insulation, mechanical strength, corrosion resistance, and wear resistance. These properties make it suitable for a variety of industrial applications, including electronics, where it's used for its insulation properties, and in machinery parts for its strength and durability. Alumina wafers are also known for their high heat resistance, thermal conductivity, and hardness. With advancements, high-purity alumina (up to 99.96%) is now available, offering improved performance in demanding applications. This high purity level results in extremely high hardness, flexural strength, and dielectric strength, making alumina wafers ideal for applications requiring superior mechanical, thermal, and electrical properties.

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance
