3004 aluminum circle also belongs to a series of AL-Mn alloy, the strength is higher than the 3003 aluminum circle, the formability/plasticity, the corrosion resistance/rust resistance is betterthan 3003 alloyaluminum circle,also commonly used in the production of cooking utensils, food warehouse transport equipment,etc.
And anodising is an electrolytic process that produces a dense, chemically stable protective aluminum oxide film that is an integral part of the underlying aluminum---it cannot peel or flake off.It enhances the natural qualities of aluminum still further; it permits a strongly contemporary finish with incomparable corrosion and abrasion resistance.Therefore,the 3004 anodised aluminum circle also can be typically used for Cookware and Lampshade after anodising.
The advantages of 3004 Anodised aluminum circle
• 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
• 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
• High reflectance,improve the lamp light reflectivity
