Product Description
Alumina ceramic (Aluminum Oxide, or Al2O3) is one of the most widely used technical ceramic materials, with an excellent combination of mechanical and electrical properties as well as a favorable cost-to-performance ratio. Wintrustek offers a range of Alumina compositions to meet your most demanding applications.
| Typical Grades | 95%, 96%, 99%, 99.5%, 99.6%, 99.7%, and 99.8% |
| Typical Properties |
Outstanding electrical insulation High mechanical strength and hardness Excellent abrasion and wear resistance Excellent corrosion resistance High dielectric strength and Low dielectric constant Good thermal stability |
| Typical Applications |
Electronic components and substrates High temperature electrical insulators High voltage insulators Mechanical seals Wear components Semiconductor components Aerospace components Ballistic armor |
Alumina components can be formed by a variety of manufacturing techniques such as dry pressing, isostatic pressing, injection molding, extrusion, and tape casting. Finishing can be accomplished by precision grinding and lapping, laser machining, and a variety of other processes.
The alumina ceramic components produced by Wintrustek are suitable for metallization in order to create a component that is easily brazed with many materials in subsequent operations.
