5657 Anodized aluminum coil sheet is a kind of fine aluminum coil sheet that anodised oxidation requires relatively high, the factory need thirty-two processing, going through the polished and anodized treatment to ensure the mechanical properties of material during using.
The 5657 Anodized aluminum Coil sheet Usage: mainly used for automotive and other equipment’s decorative part, for the decorative part requires very high demand of polishing and anodizing, etc., in any case must ensure that the material has a fine grain organization, the performance of the organization directly affect the life of the ornament.
The performance of the 5657 in the 5-series aluminum aluminum coil sheet differs from the other 5-series in terms of chemical composition and using performance, and the other 5-series cannot reach to its polishing and anodizing performance.
The advantages of 5657 Anodised aluminum coil sheet :
• Top-grade quality. Refined, luxurious and sparky surface
• Unique finish
• Low proportion, only 1/3 of stainless steel weight and easy for further fabrication
• Sapphire grade surface hardness for scratching resistance
• Environmental friendly material
• Anti-interference, shield electromagnetic wave
• High thermal conductivity, which perfectly for electronic device
• High finger print resistance and do not attract dust
• The oxidizing layer will not crach, peel off or flake
• Multiple colours can provide unlimited possibilities for device design
• Simplified flow, high yield productivity, cost saving
