Alumina Products Customized For High-Temperature And Corrosion-Resistant Components

Alumina Products Customized For High-Temperature And Corrosion-Resistant Components

 

Our high-precision alumina ceramic components utilize ultra-pure Al₂O₃ material (≥99.6% purity) specifically engineered for precision instrumentation applications. Featuring nanometer-level surface finish (Ra≤0.05μm) and micron-level dimensional accuracy (±0.005mm), these components meet the most demanding requirements in semiconductor equipment, optical instruments, and medical devices.

 

Key Applications

  • Semiconductor Manufacturing: Wafer handling arms, vacuum chamber liners, plasma nozzles

  • Optical Instrumentation: Laser mirror mounts, spectrometer slit assemblies, interferometer reference platforms

  • Medical Analysis Equipment: Mass spectrometer ion sources, chromatographic ceramic columns, PCR thermal cycling modules

  • Scientific Research: UHV flanges, cryogenic experimental platforms, synchrotron radiation optics

  • Industrial Metrology: CMM probe tips, surface profilometer reference blocks, roundness tester turntables
