Alumina Ceramic Tube Sleeve

Alumina ceramic tube sleeves, known for their excellent physical and chemical properties, are widely used across multiple industries as protective or insulating layers.

Designed with various structural forms, these tube sleeves are tailored to accommodate different application environments and functional requirements. Their key features include high density, exceptional wear and high-temperature resistance, and outstanding electrical insulation properties.

With a density of up to 3.85 g/cm³, alumina ceramics ensure stability and durability under high loads. Additionally, a Vickers hardness of 15.7 GPa enables them to maintain superior mechanical performance even in extreme environments.

Electronics Industry

Alumina ceramic tube sleeves play a crucial role in the electronics industry. Due to their non-conductive nature, they serve as protective layers for wires or sensitive electronic components, preventing electrical interference and environmental impacts. Additionally, their excellent thermal shock resistance allows them to withstand temperature variations of up to 200°C, making them ideal for high-temperature operating environments with a maximum use temperature of up to 1650°C.

Chemical Industry

The chemical industry is another key application area for alumina ceramic tube sleeves. They are commonly used as part of chemical reaction tubes to handle corrosive chemicals. With a compressive strength of up to 2000 MPa and a flexural strength of 330 MPa, these sleeves ensure structural integrity and durability during chemical reactions. Furthermore, the chemical resistance of alumina ceramics allows them to withstand various chemical media, ensuring the purity and safety of the reactions.
