Process parameters: The sulfuric acid concentration is typically 150-200g/L, with temperature controlled at 20±2℃, current density ranging from 100-200A/m² (or 1-3A/dm²), and a treatment time of approximately 30 minutes to 2 hours.
Process: Aluminum, serving as the anode, forms a porous alumina film on its surface after being electrified.
we can according customer require set special line.
Customization direction
Process parameter customization: Adjust oxidation time, temperature, solution concentration, etc., to accommodate different materials (such as aluminum, magnesium alloys) or thickness requirements.
Equipment configuration customization: Design the line length and automation level (such as robotic loading and unloading) according to production capacity requirements, or integrate specific post-processing (such as sealing and dyeing).
Function and certification customization: Enhance corrosion resistance and adhesion according to industry requirements (such as automotive and medical), and support obtaining relevant certifications (such as RoHS and ISO).
Appearance and effect customization: Provides options for different colors (such as black, colored) or gloss levels (matte, glossy) to meet decorative needs.
Aluminum Workpiece
↓
[Chemical Degreasing] → Rinse // Remove oils and contaminants
↓
[Alkaline Etching] → Rinse // Create uniform matte surface (NaOH, 50–80 g/L, 50–70°C)
↓
[Neutralization] → Rinse // Remove residual alkali (HNO₃ or mixed acid)
↓
[Anodic Oxidation] → Rinse // Form porous Al₂O₃ layer (H₂SO₄, 150–200 g/L, 20±2°C, 1–3 A/dm², 30 min–2 h)
↓
[Electrolytic Coloring (Optional)] → Rinse // Deposit metal salts for color (e.g., black, bronze)
↓
[Sealing] → Rinse // Close pores via hot water or nickel acetate (improves corrosion resistance)
↓
[Post-Treatment (e.g., Deashing)] → Rinse // Ensure surface cleanliness
↓
[Drying] (60–80°C) → [Inspection] → [Packaging]
