3003 aluminium alloy is Al-Mn alloy,which has good corrosion resistance,heat conductivity and excellent processing performance.It is widely used in architectural decoration,household kitchen utensils and appliances,refrigeration devices,electronics,aerospace and so on,and is one of the most widely used antirust aluminum. Hard anodic oxidation of aluminium is a method which means forming a dense aluminium oxide film with high hardness and thickness on the surface of aluminium,so as can improve the anti-rust corrosion and anti-static effect, and improve the service life.
The advantages of 3003 Anodised aluminum coil :
• 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
