Alumina Ceramic Tube Square
My factory looking for distributors.
Square tube size: 25*25*400mm
Advantages of Alumina Ceramic Tube Square
The high mechanical strength, wear resistance, corrosion resistance, and thermal shock resistance of alumina ceramic tubes ensure the extension of their service life. The superior electrical insulation performance makes it indispensable in electrical applications, preventing short circuits and electrical faults. Chemical inertness enables safe use in corrosive chemical environments and maintains product integrity. Alumina ceramic tubes accurate dimensions and customizable shapes allow for tailored solutions.
Application of Alumina Ceramic Tube Square
1. Customized alumina ceramic tube square tube, mainly composed of alumina (Al2O3), has high thermal conductivity, excellent electrical insulation, outstanding mechanical strength, as well as excellent corrosion resistance and wear resistance.
2. Alumina ceramic tubes make them an ideal choice for insulating substrates, connectors, and components in electronic systems.
3. Square alumina ceramic tubes are suitable for applications such as kiln furniture, furnace lining, and insulation layers.
4. Alumina ceramic tube squares are employed in various applications, including biomedical implants and laboratory equipment.
