 Alumina Ceramic Custom Finishing


Alumina ceramic structural parts


Alumina ceramics are also known as precision ceramics, special ceramics, structural ceramics, or high-tech ceramics. It is a ceramic with highly selected raw materials, produced according to a special manufacturing process, which can precisely control the chemical composition and has excellent properties. Currently, alumina ceramics are mainly used in high-tech and cutting-edge industries, such as microelectronics, nuclear reactors, aerospace, magnetic fluid power generation, artificial bone and artificial joints.

 

Main features of high-precision ceramic parts
1. Highly precise dimensions with tight tolerances, making it easier to obtain a perfect fit.
2. wear & abrasion resistance: aluminium oxide is an extremely hard technical ceramic with excellent wear resistance.
3. High temperature resistance: up to 1650°C in oxidising and reducing atmospheres.
4. chemically inert, resistant to most strong acids and bases, and will not rust permanently
5. Electrically insulating: Dielectric breakdown of at least 18 KV.
6. excellent mechanical properties, hardness, compressive and flexural strength much higher than stainless steel
7. chemical corrosion resistance at high temperatures, even with strong acids or bases
8. Protective atmosphere at high temperatures or high vacuum to eliminate contamination or impurities. 9.
9. low material costs in advanced applications compared to other technical ceramics
