What is aluminium foil?
Aluminium (otherwise known as Aluminum in America) foil is a paper thin sheet made of pure aluminium. There are also many other alloys and tempers which can be used to make aluminium foil and give a wide range of tensile properties. It is produced in many different widths and strengths, and varies from 0.00017 in. - 0.0059 in. thick. This makes it easy to tear and mould into different shapes, which helps when people wrap aluminium foil around food to keep the moisture out and flavours in, so it lasts longer. This is just one of the many uses for aluminium foil, and since it is so popular and mass produced it does have many other uses, some of which are very abnormal. Not to mention how it can be used to 'protect your mind from aliens'.
Manufacturing Process
There are two processes used to extract pure aluminium from bauxite, which is needed in order to make aluminium foil. Firstly, the ore is refined, eliminating impurities including iron, oxide, silica, titania and water. In the second process the resultant oxide is smelted for pure aluminium, then it is rolled to produce foil.
