For alumina tile products, discs, rods or tubing IPS Ceramics manufactures and supplies a full variation of high alumina ranges around the world. It is the most widely used technical ceramic and is the material of choice in about 80% of engineering applications due to its combination of properties. Fired at over 1600°C (2900°F) to give a fully dense technical ceramic, alumina exhibits high mechanical strength, rigidity and can be machined to tight tolerances and fine surface finishes. Alumina is often used as a replacement for metallic components in demanding engineering applications.
Alumina Tile, Rod, Disc and Tube Properties
Alumina tile is ideal for manufacturing wear-resistant inserts or products such as mill or chute linings, cam discs, location or centering pins for welding, thread guides and friction discs for textiles. This is because technical ceramics such as alumina tile, rods, discs and tubes are very hard-wearing and resistant to abrasion. High alumina is:
- Thermally stable
High alumina can be used in both oxidizing and reducing atmospheres up to 1600°C (2900°F) and in vacuum furnaces up to 2000°C (3600°F).
- Resistant to chemicals
High alumina is chemically inert and is not corroded by water or steam. It offers good resistance to strong acids and alkalis at elevated temperatures and is ideal for applications where resistance to corrosive substances is required. Alumina is often used for catalyst supports operating at high temperatures. It is also an obvious choice for pump and valve components when its excellent abrasion resistance is considered.
- An electrical insulator
Alumina is widely used as an electrically insulating material, particularly the higher purity grades which have enhanced resistivity. It can be used for insulators operating at elevated temperatures (e.g. furnace lead-in tubes, fuel cells).
- Has high thermal conductivity
Alumina has reasonably high thermal conductivity for a ceramic. It is often used as a substrate for semiconductors and high-performance heat sinks and thermal control products.
Find Out More About Alumina
The strong all-around performance of the alumina tile and other products made of this material has long been proven in some demanding applications including the automotive, aerospace, defence, medical, electrical and heat treatment industries.
Alumina is a highly flexible material when it comes to product development, and we are always working with design engineers and system manufacturers to come up with new applications. Alumina components can be threaded, perforated, rebated, slotted, hollowed or tapered to suit thousands of design and performance demands. Complex shapes are often achievable, and they also lend themselves to surface treatments where required, such as precision grinding and lapping.
IPS Ceramics offers a range of premium quality alumina materials, from 90% right up to 99.7% alumina.
