Description of Alumina Ceramic Parts
Aluminium oxide, or Alumina, distinguishes itself with an array of applications, recognized for its versatile nature and cost advantages over other advanced ceramics. Renowned for its supreme electrical insulation, resistance to extreme temperatures, remarkable hardness, wear resistance, and excellent chemical stability, Alumina is the material of choice in high-temperature and corrosive settings.
Our cutting-edge manufacturing facility crafts alumina components, boasting purities from a solid 75% to a near-perfect 99.8%. Utilizing advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we create dense ceramic bodies. For specialized needs requiring superior fitting, reduced friction, and enhanced insulation, we offer advanced secondary processes, such as CNC machining, polishing, glazing, and metalizing after sintering.
We excel in creating a diverse range of alumina ceramic products-including rings, tubes, discs, rods, arms, and wire guides-offering services from prototyping to large-scale production. Trust us to provide solutions meticulously tailored to your precise specifications.
