The Science Behind Aluminum Oxide Film

Aluminum oxide (Al₂O₃) film represents a pinnacle of abrasive material engineering, combining exceptional hardness (9 on Mohs scale) with controlled fracture characteristics. Unlike conventional abrasives, our precision-engineered films feature:

• Monocrystalline structure for consistent particle geometry
• Electrostatic deposition technology ensuring uniform particle distribution
• Thermally stabilized substrates preventing dimensional instability

These characteristics enable aluminum oxide film to achieve surface finishes down to Ra 0.01μm, making it indispensable for optical components and semiconductor substrates.

Material Properties Comparison

Industrial Applications Redefined

XYT's aluminum oxide films have transformed surface finishing processes across multiple industries:

Optics Manufacturing

Our optical polishing pads integrated with Al₂O₃ films achieve:

• λ/20 surface flatness for telescope mirrors
• Scratch-free finishes on AR/VR lens coatings
• Sub-nanometer roughness for laser optics

Aerospace Components

The aviation industry benefits from our film's ability to:

• Maintain tight tolerances on turbine blade profiles
• Remove recast layers from EDM-processed parts
• Prepare surfaces for thermal barrier coatings

Technical Advantages Over Alternatives

While silicon carbide abrasives and diamond lapping films have their merits, aluminum oxide offers distinct benefits:

Versatility

Our films adapt to both ferrous and non-ferrous materials without the galvanic corrosion risks associated with diamond abrasives in metalworking.

Process Control

The self-sharpening nature of aluminum oxide particles ensures:

• Stable cutting rates throughout the tool life
• Predictable surface roughness progression
• Reduced need for intermediate dressing

XYT's Manufacturing Innovations

Our 12,000㎡ facility incorporates breakthrough technologies that enhance aluminum oxide film performance:
