Ultra-High-Temperature Easy-to-Machine Alumina Ceramic Sheets
- Color: White
- Max. Temperature: 3000° F
- Fabrication: Fired
- Porosity: 48%
- Compressive Strength: 4,350 psi
Commonly used in induction furnace components and hot glass handling, this alumina ceramic withstands higher temperatures than alumina-bisque ceramic. The 99% alumina content makes it suitable for high-vacuum applications. It has excellent machinability. Material comes fired and is unaffected by water.
