Alumina ceramics have a wide range of applications due to their versatility and lower material cost than other advanced ceramics. Alumina ceramics have excellent properties such as high temperature resistance, strong hardness, wear resistance, good electrical insulation, and good chemical stability.
The alumina ceramic parts we supply have dense bodies, which are made by dry pressing, hot pressing, ceramic injection molding (CIM) or isostatic pressing. In order to achieve some special fitting, reduce friction and increase insulation, we provide a series of secondary processing after sintering, including CNC machining, polishing, glazing and metallizing.
We supply a variety of alumina tubes in shapes such as special-shaped, slotted, threaded, square, hexagonal, flanged, single / double / four / multiple holes, closed at one end, half pipe, etc.
Depending on the product process, the specifications we can achieve are also different. The following is for reference only.
| 1 | Outer Diameter | Up to 600mm |
| 2 | Inner Diameter | Min. 1mm |
| 3 | Thickness | Min. 1.5mm |
| 4 | Length | Up to 1000mm |
| 5 | Roughness | Outer surface Ra0.1, inner surface Ra0.4 (after polishing) |
| 6 | Glaze Layer Thickness | 0.15mm (general) - When glazing is required |
| 7 | Metallization Layer Thickness | Evaluated based on specific product - When metallizing is required |
Alumina tubes have a wide range of applications. Here are some typical application scenarios.
1. Used as protective sleeves for temperature measuring elements - thermocouples.
2. Used to transport sand, coal, ash, liquid aluminum and other wear-resistant granular materials and corrosive media.
3. Used as refractory materials for high-temperature electric furnaces, high-temperature kilns, etc.
4. Tubes for threading wire or yarn on textile equipment
5. Igniter insulators for gas stoves, internal combustion engines and other ignition devices.
Jinghui Ceramic specializes in the production of alumina tubes. The design and size of the product can be customized according to specific application needs. As far as the material is concerned, we more commonly use 75% / 95% / 99% / 99.5% alumina ceramic materials.
We are an ISO9001 quality management system certified manufacturer. Whether it is proofing or large-volume requirements, we believe we can provide you with the ideal solution.
