Laser-Processed Alumina Ceramic Sheet

Laser-Processed Precision Alumina Ceramic Sheets represent a synergy of advanced material science and cutting-edge laser technology, delivering exceptional precision and performance for high-tech applications.

Crafted from high-purity alumina (Al₂O₃) substrates—available in grades from 90% to 99.9% purity—these sheets undergo laser processing to achieve intricate features with unparalleled accuracy. Laser machining, leveraging high-energy laser beams, enables the creation of micro-scale patterns, fine holes (down to 50μm in diameter), precise cuts, and complex geometries that traditional mechanical methods struggle to replicate. This process ensures minimal material damage, with no tool wear or mechanical stress, preserving the ceramic’s inherent properties such as high hardness (Mohs 9), excellent thermal stability (up to 1600°C for 99% grades), and superior electrical insulation (volume resistivity >10¹⁴ Ω·cm).

The precision of laser processing results in tight tolerances (often within ±0.01mm) and smooth edge finishes (Ra ≤ 0.2μm), critical for applications in electronics, where these sheets serve as substrates for circuit boards or heat sinks; in aerospace, as lightweight structural components; or in medical devices, where biocompatibility and dimensional accuracy are paramount.
