Alumina Ceramics
Aluminium Oxide (Alumina) is the most widely used ceramic material with near limitless manufacturing capabilities. They are grouped together based on purity levels, as the purity of Alumina’s increases wear and corrosion resistance also increases. Alumina’s are used in a variety of general-purpose applications, and their grade is chosen based on the application environment. Higher purity Alumina’s can be formulated for more demanding applications.
Typical Applications Include: Wear resistant components, High pressure nozzles, Thermocouple tubes, Electrical Insulators, Corrosive labware, Furnace fixtures, Ballistic armor, Thread guides, Laser Tubes, and Pump seals.
Properties of Alumina Ceramics
Alumina Ceramics are the most highly regarded and widely used of the ceramic products. It is non-conductive, resistant to corrosion, and are perfect for electrical insulation. Alumina Ceramic has proven to be the best ceramic for protection of vital electrical components. It can be processed as tubing, sheets, bars, rods, discs, and many other forms depending on the requirements of the project.

FAQ
Q1. How to quickly obtain a quote.
A1. Provide detailed dimensions and quantities of the products you require. What is the purpose of the product. Customization of drawings can also be provided.
Q2. What are the benefits of alumina ceramics?
A2. Alumina ceramics is a widely used material because it can be produced in a range of purities—from 85 to 99.9 percent pure—that provide unique benefits. Generally, alumina ceramic components offer quality strength, hardness, corrosion resistance, and thermal stability.
A3. Alumina is often used as a replacement for metallic components in demanding engineering applications. IPS Ceramics supply 95% alumina for applications below 1450 ºC / 2650 °F and 99% alumina for temperatures up to 1600 ºC / 2900 °F or where contamination of the sample must be avoided.
A4. Alumina shares several characteristics with other polycrystalline ceramic materials, such as moderate tensile and bending resistance and the brittle fracture behavior, which is the main disadvantage of the mechanical properties of alumina.
