Aluminium Oxide Fastening Elements Description
Aluminium oxide fastening elements are a fine ceramic material used in various industrial sectors. This material provides electrical insulation, chemical resistance and low thermal expansion. High-purity aluminium oxide ceramics are employed for the manufacture of components for CVD, ion implantation, photolithography and semiconductor parts. In conventional industry, aluminium oxide ceramics are used for products such as injection tubes, gas nozzles and insulators. Aluminium oxide fastening elements are produced from materials with low coefficients of thermal expansion and measured wear resistance.

Prototyping service available for other ceramic materials
1. High-temperature environments: Aluminium oxide fastening elements are used in applications such as furnaces, kilns and heat treatment facilities, where metal fasteners fail due to oxidation and loss of strength.
2. Chemical processing: Aluminium oxide fastening elements are used in chemical processing facilities. They are resistant to aggressive chemicals, acids and alkalis, thereby suitable for reactors, storage tanks and pipelines.
3. Electrical insulation: Owing to their electrical insulation properties, aluminium oxide fastening elements are employed in electrical and electronic devices to secure components and maintain electrical isolation, particularly in high-voltage applications.
4. Semiconductor manufacturing: They are used in the semiconductor industry where high purity and resistance to thermal and chemical processes are critical. Aluminium oxide fasteners secure devices and components in clean room environments.
5. Aerospace and defence: They are utilised in aerospace and defence, where light, high-strength and temperature-resistant materials are required for components that are exposed to extreme conditions.
6. Medical and dental devices: They are used in medical and dental instruments and devices owing to their biocompatibility, resistance to sterilisation processes and ability to maintain structural integrity over prolonged periods.
7. Analytical and laboratory equipment: They are employed in laboratory and analytical instruments where resistance to high temperatures, chemicals and thermal shock is essential for precise and reliable performance.
8. Mechanical and structural components: Suitable for applications that require high strength, wear resistance and stability during temperature fluctuations, for example in engines, pumps and machinery.
9. Optical and laser systems: Employed in optical and laser systems to secure components where thermal stability and minimal thermal expansion are required to maintain alignment and performance.
