Specifications

• 1100

Summary

• Widely used in fin stock
• Heat exchanger fins
• Spun hollow ware
• Dials and name plates
• Decorative parts
• Giftware
• Cooking utensils
• Rivets
• Reflectors
• Sheet metal work
• Greyish-white in colour, it is malleable, ductile and conductive to heat and electricity
• A thin inert film of oxide protects the metal surface from further attack, thus giving the metal a form of resistance to corrosion.
• This film of oxide can be further thickened by a process known as the anodizing
• Welding can be made possible.
• Anodized or spray coating possible to achieve different architectural effects
• With its non-corrosive and good mechanical properties, each grade of Aluminium has a high range of applications.
• Aluminium also possesses very high malleability, enabling it to be produced into a very thin foil.
