As a alumina ceramics products manufacturer.We can offer alumina ceramics products with different proportions（95%-99.99% Al2O3).
Alumina ceramic is a kind of ceramic material mainly composed of alumina (Al2O3).Alumina ceramics have good conductivity, mechanical strength and high temperature resistance and other capabilities.
1.Very good electrical insulation (1x1014 to 1x1015 Ωcm)...
2.Moderate to extremely high mechanical strength (300 to 630 MPa)....
3.Very high compressive strength (2,000 to 4,000 MPa)...
4.High hardness (15 to 19 GPa)...
5.Moderate thermal conductivity (20 to 30 W/mK)...
6.High corrosion and wear resistance...
7.Low density (3.75 to 3.9 g/cm3)...
8.Operating temperature without mechanical load 1,000 to 1,750°C....
9. Other excellent property
·Flexural strength·Chemical resistance·Electrical insulation ·Corrosion resistance·Dielectric strength·Wear resistance
·Temperature resistance·Thermal conductivity·High voltage·Hardness...
· 95%--99.99% Alumina (Al2O3)
High purity alumina ceramics:
99.99% Alumina ceramic; 99.9% Alumina ceramic,
Ordinary alumina ceramics:
99.7% Alumina ceramic,99.5% Alumina ceramic,99% Alumina ceramic,97% Alumina ceramic,96% Alumina ceramic,95% Alumina ceramic
Note: different industries, different environments, different equipment, different products have different requirements on the composition of alumina, different alumina ceramic components have different performance and service life.
