What is Anodized aluminum circle
It forms a dense oxide film on their surface, possessing high hardness, wear resistance, corrosion resistance, and excellent insulation. It also offers a pleasant appearance, can be colored, have stable dimensional accuracy, and are not easily deformed.
It is commonly used in heat sinks and decorative panels for electronic appliances, and are also widely applied in lamp reflectors, kitchenware, instrument housings, and hardware accessories, combining practicality and aesthetics.
Anodized aluminum round plate specification
Alloys | 1050, 1060, 1070, 3003, 5052 |
Tempers | O, H14, H16, H18, H28,etc. |
Diameter | 10mm–1200mm |
Size tolerance | ±0.1mm High precision requirements can be met with ±0.05mm. |
Anode type | Sulfuric acid anodizing (conventional), hard anodizing |
Film thickness and tolerance | Conventional anodizing: 8–12μm, ±2μm Hard anodizing: 25–50μm, ±3–5μm |
Color and color difference control | Natural (silver-white), black, champagne, gold, silver, blue, red, etc. Within the same batch: ΔE ≤ 1.5–2.0 (CIE Lab color space) Between batches: ΔE ≤ 2.0–2.5 |
Surface quality standards | No obvious scratches, dents, pinholes, black spots, oxide film peeling, or exposed substrate. Edges are free of burrs and chipping; chamfers are uniform. |
Corrosion/abrasion resistance indicators | Corrosion resistance: Ordinary anodized films show no significant rust after 168–336 hours of neutral salt spray testing (NSS); thick film/hard anodized films can reach over 500 hours. Abrasion resistance: Ordinary anodized films have a hardness of approximately 200–300 HV; hard anodized films can reach a hardness of 300–500 HV, significantly improving abrasion and scratch resistance. |
Surface Roughness Ra | Original substrate surface: Ra 0.6–1.6μm After ordinary anodizing: Ra 0.8–2.0μm After mirror/fine polishing anodizing: Ra ≤ 0.4μm, commonly used for high-gloss and reflective parts After hard anodizing: Ra 1.6–3.2μm, thicker film, slightly increased roughness |
