what are the differences between aluminium , iron , steel.... properties like strength , durability , corrosion resistance properties...finally which is cost efficient and best for all purpose..??
Duraluminium is cost efficient and best for all purpose.
Brass is an alloy made of copper and zinc, and will show shades of yellow in it. Musical instruments are made from this as well as ornaments, military buttons etc. Bronze is made from copper and tin, and will appear browner in content. This allow is stronger than brass, and can be used for weapons, long lasting household items, etc.
the difference between iron, steel aluminium is that aluminium contains no carbon as iron steel do. Iron steel over time will rust but aluminium wont. In taking out carbon out off iron to make steel is it needs the carbon % to be less than 0.5% as with iron it still contains carbon at 1.5% to 2% so is not a very strong metal and steel. In Strength Steel is stronger than aluminium and also weights heavier than aluminium. Aluminium do sent corrode because it do sent contain iron as with steel it dose as oxygen reacts with it over time causing it to rust. This is why a coat of red oxide paint is put on it for finishing purposes. In cost efficient steel is the cheaper as steel is a faster process in making it. As you only need 3 ingredients which are Iron ore, Coke which is coal burnt to take off impurities and leaves carbon. As with Aluminium it is more expensive as an expensive process to make and the ore and can only be mined in sear-tonn countries such as Australia. Hope this Helps :o)
take Mechanics of Materials course next semester.. cuz there's so much to tell which can't be covered in a single answer!
