5 FAQs of Laser Cutting Al2O3 Alumina Ceramic Substrate

What is Al2O3 alumina ceramic substrate?
Al2O3 alumina ceramic is a material made from aluminum oxide. It is hard, resists high heat, and insulates electricity. It is used in electronics, machinery, and medical devices. It handles extreme temperatures and harsh chemicals well.

Why use laser cutting for Al2O3 substrates?
Laser cutting is precise and causes little damage. It works for complex shapes and thin materials. The laser beam melts or vaporizes the ceramic cleanly. Heat stays controlled near the cut area. This reduces cracks or warping.

What defects occur during laser cutting?
Cracks or rough edges may form. This happens if the laser power is too high or speed too fast. Thermal stress from uneven cooling can also cause breaks. Proper settings and cooling systems lower these risks.

What thickness can laser cutting handle?
Most lasers cut Al2O3 up to 2 mm thick. Fiber lasers manage up to 5 mm. Thicker pieces need multiple passes. Thicker cuts take longer and may need extra polishing.

Is post-processing needed after laser cutting?
Yes. Remove debris with air or water cleaning. Grind or sand edges for smoothness. Annealing may reduce residual stress. Check dimensions and quality before use.
