Product Description
Electrical Insulation Al2O3 Alumina Ceramic Substrate Plates
Alumina ceramic ( Aluminum Oxide or Al2O3 ) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics & electrical, pump components and automotive sensors, medical, semiconductor, furnace parts...
UNIPRETEC offers a variety of alumina compositions, typical grades that are used for modern industrial applications are of high purity from 90% to 99.7%.
Alumina components can be formed by a variety of manufacturing techniques such as dry pressing, cold isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining, metallizing and a variety of other processes. |
Overview of typical properties: • Good electrical insulation; • High mechanical strength; • Excellent wear resistance; • Excellent corrosion resistance; • Low dielectric constant; • High using temperature; • High thermal shock resistance... | Overview of typical applications: • Pump seals and other components; • Wear resistant inserts; • Insulating washers or bushings; • Semiconductor components; • Aerospace components; • Automotive sensors; • Electrical or electronic insulators... |

Q1: What are advanced ceramics? >>> Advanced ceramics - also referred to as engineering, structural or technical ceramics - have been processed to be very pure and, in general, have superior properties to unrefined ceramics. Many are man-made, i.e. they do not occur naturally, e.g. silicon nitride, and their properties can be enhanced to produce very high strength at high temperatures, good corrosion resistance, etc. |
