Customised Components from Aluminium Oxide – Description
Customised Components from Aluminium Oxide exhibit high thermal conductivity, compressive strength and thermal shock resistance. Aluminium oxide is a ceramic material that offers high thermal conductivity, compressive strength and thermal shock resistance. Moreover, it features low thermal expansion, thereby making it a suitable material for use in furnaces in the form of crucibles, tubes and thermocouple sheaths. Aluminium oxide also exhibits high hardness and good wear resistance, which makes it appropriate for ball valves, piston pumps and deep-drawing tools. It can be easily combined with metals and other ceramic materials through hard soldering and metallisation.

*This chart shows the typical properties of standard Aluminium Oxide materials that are used in the production of our customised Aluminium Oxide components. Please note that the properties of customised Aluminium Oxide parts may vary according to different processing methods. Stanford Advanced Materials can supply you with Aluminium Oxide products manufactured in accordance with your specifications, or they endeavour to meet the requirements of their customers.
Applications for Customised Aluminium Oxide Components
Customised Aluminium Oxide components, manufactured from high-purity aluminium oxide (Al2O3), are utilised in diverse industries because they possess thermal conductivity, compressive strength and chemical inertness. In electronics and electrical engineering, the components serve as insulators and precision substrates in high-voltage applications and semiconductor devices. In medical and dental fields, they serve in orthopaedic implants and dental components, demonstrating biocompatibility and durability. In industrial manufacturing, they provide wear resistance in parts, customised cutting tools and machine components. In aerospace and defence, they are used for heat shields, insulation and armour. In chemical processing, they serve as reactor components and catalyst carriers. Optical and laser systems employ them as optical components and in precision lenses. In renewable energy, the parts are integrated in solar cells, photovoltaic devices and fuel cells. Additionally, the food and beverage industry utilises aluminium oxide parts in sanitary processing equipment. Their high melting point, stable insulating properties, mechanical strength and chemical resistance render them suitable for various applications.
Packaging of Customised Aluminium Oxide Components
Our customised aluminium oxide components are handled with care to prevent damage during storage and transport and to maintain their quality in its original condition.
