Alumina ceramic parts custom and machinable AL2O3 alumina spare part components 


The al2o3 alumina ceramic parts as a kind of the industry equipment spare components was made of the mainly alumina ceramics raws:95% — 99.99%. The different chemical composition and structure of alumina ceramics determine their different special properties and functions, such as high strength, high hardness, high toughness, corrosion resistance, etc. 


Properties of Alumina/Aluminum Oxide (Al2O3)
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.Good gliding properties
8.Low density (3.75 to 3.9 g/cm3)
9.Operating temperature without mechanical load 1,000 to 1,500°C.
10.Bioinert and food compatible
