Product Description Custom Industrial High Voltage Al2O3 Alumina Aluminum Oxide Electrical Ceramic Insulator Tube Product IntroductionWith our machining and manufacturing capabilities, Jinghui Ceramics can offer a wide range of standard and customized alumina ceramic insulator tubes. They are regularly made from high-purity aluminum oxides such as 95%, 99%, 99.5% and 99.8% depending on the applications in the different fields. In order to cater the precise fitting relationship, some secondary processes have to be conducted at-house, including fine grinding, drilling, tapping and CNC machining. Therefore, we can meet various technical specifications and grades of ceramic tubes in the market to achieve customers' demanding needs. Aluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability. This makes it an ideal material choice for applications requiring high temperature and corrosion resistance. The specification Option Materialsvarious purities of alumina from 40% to 99.8% and steatite ceramic Outer diameter 0.5 ~800 mmLength1~1000mmRoughnessTo be Ra0.1Surface treatmentPolished, Glazed, Metalized availabilityCosmeticSmooth surface without no contamination, deformation, and crackThe accuracy achieved after precision machining(1) Axis: roundness 0.002 mm, concentricity 0.002 mm, smoothness Ra0.1;(2) Hole: the minimum processing hole diameter is 0.2 mm, and the depth is up to 6mm;(3) Slot: min. value to be 0.1 mm of narrow groove, and grooves with custom shapes;(4) Plane: 0.1mm sheet with minimum processable thickness, parallelism 0.001mm, measurement tolerance 0.001 mm, finish Ra0.1; (5) Thread: The minimum machinable M2 internal thread, the accuracy of GB-7h, the external thread size is not limited, and the accuracy is GB-6g.
