280x220mm Aluminum Oxide Lapping Film Sandpaper – 5-Pack – Precision Abrasive for Metal, Glass, Ceramic & Gemstone

Aluminum Oxide Lapping Film Sheets are engineered for ultra-precise surface finishing, delivering exceptional flatness and smoothness for demanding applications in industries such as electronics, optics, materials science, and advanced manufacturing. These sheets combine high-purity aluminum oxide abrasives with durable polyester film, offering reliable, uniform performance on metal, glass, ceramics, and gemstones.

Key Features

Precision Aluminum Oxide Abrasives

• Uniform Particle Distribution: Resin-bonded, tightly graded aluminum oxide particles ensure consistent material removal and smooth, scratch-free finishes.

• Durable Polyester Backing: High-strength PET backing resists tearing and provides superior dimensional stability during precision lapping.

Wet/Dry Compatibility

• Optimized for both wet (water or coolant-assisted) and dry workflows, reducing heat and enhancing finish quality.

Material Versatility

• Effective on metals, alloys, optical glass, ceramics, fiber optics, gemstones, and composite materials.
