Aluminium Oxide, Al2O3 is a major engineering material. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.
Alumina can be produced in a range of purities with additives designed to enhance properties. A wide variety of ceramic processing methods can be applied including machining or net shape forming to produce a wide variety of sizes and shapes of component. In addition it can be readily joined to metals or other ceramics using metallising and brazing techniques.
Alumina based ceramics are by far the largest range of advanced ceramics made by UNIPRETEC. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our Alumina products to give you the best possible component.
Typical Alumina characteristics include:
* Good strength and stiffness
* Good hardness and wear resistance
* Good corrosion resistance
* Good thermal stability
* Excellent dielectric properties (from DC to GHz frequencies)
* Low dielectric constant
* Low loss tangent
Product Specification / Models
Has very good electrical and mechanical properties and is metallized easily. The black body is used primarily for lids and when metallized and plated with gold has a very distinct appearance.
Possess very good electric and mechanical properties and is very easily metallized with the MoMn process.
This is our standard body and it has been formulized to meet with good success with just about anyone's MoMn process. This body still possesses the same good mechanical and electric properties as the previous two alumina bodies.
This body is used extensively in the medical industry. Its finer grain allows it to be polished to achieve fine micron finishes making it the material of choice for pump manufacturers and it is used for wire/thread guides as well as for mechanical seals. Though it can be metallized it normally does not lend itself to that process due to its lack of glassy phase.
Application / Models
Typical Alumina applications include:
* Seal rings
* Medical prostheses
* Laser tubes
* Electronic substrates
* Ballistic armour
* Thermocouple tubes
* Electrical insulators
* Grinding media
* Wear components
