High Purity Alumina Components / Alumina Bushing / Alumina Sleeve with Groove

Tag Key words : Alumina Components / Alumina Bushing / Alumina Sleeve

Alumina is the more common name of Aluminium Oxide and is a hard wearing material used for many applications. Once fired and sintered, it can only be machined using diamond-grinding methods.

Aluminium oxide is an electrical insulator but has relatively high thermal conductivity (35 W/m K). In its most commonly occurring crystalline form, called corundum or a-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.

Aluminium oxide is responsible for metallic aluminium's resistance to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of alumina quickly forms on any exposed aluminium surface. This layer protects the metal from further oxidation. The thickness and properties of this oxide layer can be enhanced using a process called anodising. A number of alloys, such as aluminium bronzes, exploit this property by including a proportion of aluminium in the alloy to enhance corrosion resistance. The alumina generated by anodising is typically amorphous, but discharge assisted oxidation processes such as plasma electrolytic oxidation result in a significant proportion of crystalline alumina in the coating, enhancing its hardness.

Alumina's combination of hardness, high temperature operation and good electrical insulation makes it useful for a wide range of applications. Alumina is the most commonly used type of ceramic and is available in purities up to 99.99%.

Different types aluminium oxide ceramics:

- 95% Al2O3
- 97% Al2O3
- 99% Al2O3
- 99.5% Al2O3

- 99.99% Al2O3

Applications of Alumina Components :

High Temperature and Aggressive Environments
Its high free energy of formation makes alumina chemically stable and refractory, and hence it finds uses in containment of aggressive and high temperature environments.

Wear and Corrosion Resistance
The high hardness of alumina imparts wear and abrasion resistance and hence it is used in diverse applications such as wear resistant linings for pipes and vessels, pump and faucet seals, thread and wire guides etc.

Biomedical
High purity aluminas are also used as orthopaedic implants particularly in hip replacement surgery.

Metal Cutting Tools
The high “hot” hardness of alumina have led to applications as tool tips for metal cutting (though in this instance alumina matrix composites with even higher properties are more common) and abrasives.

Milling Media
Alumina is used as milling media in a wide range of particle size reduction processes.

Microwave Components
The high dielectric constant coupled with low dielectric loss particularly at high frequencies leads to a number of microwave applications including windows for high power devices and waveguides.

Electrical Insulation
The high volume resistivity and dielectric strength make alumina an excellent electrical insulator which leads to applications in electronics as substrates and connectors, and in lower duty applications such as insulators for automotive spark plugs
