What is aluminium used for, and why? ?
Boat people? Oriental or whatever? That's derogatory insultingWell I am not sure where you are located, but here in the US referring to any one as boat people, Oriental or whatever is a little rudeConsider it as a cultural difference, but I am sure if you slightly rephrase your question you may get more replies!
Aluminium is used in an enormous variety of products, due to its particular propertiesIt has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance, and can be easily cast, machined and formedIt is also non-magnetic and non-sparkingIt is the second most malleable metal and the sixth most ductileIt is therefore extensively used for kitchen utensils, outside building decoration and in any area where a strong, light, easily constructed material is neededIt's also extremely lightweight, so alloys of aluminium are used in aircraft, boats and rockets to reduce weight while keeping a degree of strengthAlso, when evaporated in a vacuum, it can be used as aluminium paint, which is highly reflective and better than silver coatingsIt's used to coat the insides of telescopes, decorative paper, packagings and toys, and lots of other uses.
Boat people? Whats wrong with you?
Desi is right, you are being insulting! Can you think of any other good reason you have now asked basically the same question FOUR TIMES without apparently getting the answer you are looking for?
