99 Alumina Ceramic Custom Finishing


Alumina Ceramic sheet laser processing


Alumina, also known as Aluminum Oxide or Al2O3, is a frequently used ceramic material in a wide variety of industrial, medical, and electronic applications with many mechanical and thermal properties. We supply precise laser cut & machined alumina 96 and 99 substrates made to your design.


Alumina is highly valued for its excellent resistance to high temperatures and corrosive environments, making it ideal for applications in the aerospace, automotive, and semiconductor industries. Its exceptional hardness and wear resistance also make it a popular choice for components requiring durability and longevity. Additionally, alumina's biocompatibility and non-toxic nature have led to its use in medical implants and prosthetics. The precise laser cutting and machining of alumina substrates ensure tight tolerances and high-quality finishes, meeting the stringent requirements of various applications. With its versatility and reliability, alumina continues to be a preferred material for cutting-edge technological advancements across different sectors.
