Applications Of Alumina

Alumina ceramics are characterized by extremely high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance and biological inertness. As a result, Al2O3 ceramic products are ideal for many industries, such as:
1. Electrical wires and wire conduits;
2. Mechanical seals;
3. Machine parts;
4. High temperature electrical insulators;
5. High voltage insulators;
6. Electronic parts substrates;
7. Roller and ball bearings;
8. Wear-resistant linings;
9. Semiconductor parts;
10. Precision shafts and axes in high wear environments.

Properties Of Alumina (From 95%-99.8%)

1. Excellent electrical insulation (1 × 10 14 ~ 1 × 10 15 Ω cm);
2. Medium to ultra-high mechanical strength (300 to 630 MPa);
3. Very high compressive strength (2000 to 4000 MPa);
4. High hardness (15 to 19 GPA);
5. Medium thermal conductivity (20 to 30 W / MK);.
6. High corrosion and wear resistance;
7. Good grinding performance;
8. Low density (3.75 to 3.95 g / cm3);
9. Operating temperature of 1000 to 1500°C without mechanical load;
10. Biological inertia, food compatibility.
