Is it environmentally friendly?

Yes, low-waste oxidation process.

Is it suitable for aluminum alloys?

Yes, designed specifically for aluminum.

How is the corrosion resistance?

Excellent, blasting improves adhesion.

What’s the difference between matte and glossy?

Matte retains texture, glossy is polished for shine.

Processing Overview

Description: The surface is first bead-blasted to clean (Ra 1.6-3.2μm), followed by Type II anodizing (sulfuric acid electrolyte, thickness 10-25μm) to form a protective oxide layer. Matte versions retain the blasted texture, while glossy versions are polished. The process includes blasting pretreatment, plating, and sealing, with a total time of 1-4 hours.

Applicable Materials: Aluminum and its alloys (such as 6061 and 7075).

Visual Appearance: Matte satin or glossy metallic tones with uniform texture and stable color.

Advantage

Enhanced Adhesion: The blasted texture improves the adhesion of the oxide layer and resists peeling.
Dual Protection: Combines mechanical cleaning and chemical corrosion resistance, extending product life by 20-30%.
Aesthetics and Flexibility: The matte finish hides defects, while the gloss finish enhances gloss, making it suitable for consumer products. Wear and Weather Resistance: The oxide layer resists scratches, and the sandblasted texture is non-slip.
Eco-Friendly and Efficient: The process is low-waste and suitable for medium-volume production.
Multiple Applications: Ideal for electronic housings or automotive trim.

Precautions

Sequential Control: Sandblast before oxidation to avoid texture damage; test for texture retention.
Uniform Thickness: Matte versions have a thickness of 10-15μm, glossy versions 15-25μm; avoid unevenness.
Sealing: Choose hot water or nickel salt sealing for enhanced corrosion resistance.
Design Considerations: Design for uniform wall thickness and plan shielded areas to protect threads.
Quality Standards: Comply with MIL-A-8625 Type II, checking thickness, color, and adhesion.
Safety Measures: Wear protective gear when sandblasting, and control acid mist emissions during oxidation.
