Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
The history of aluminium was shaped by the usage of its compound alum. The first written record of alum was in the 5th century BCE by Greek historian Herodotus. [2] The ancients used it as a dyeing mordant, in medicine, in chemical milling, and as a fire-resistant coating for wood to protect fortresses from enemy arson. [3] Aluminium metal was ...
Charles Martin Hall (December 6, 1863 – December 27, 1914) was an American inventor, businessman, and chemist.He is best known for his invention in 1886 of an inexpensive method for producing aluminium, which became the first metal to attain widespread use since the prehistoric discovery of iron.
Too late to cancel the mission or divert the probes there was no time to go through “normal design reviews”. So NASA’s scientists wrapped the cables in a whole lot of aluminum foil and found ...
[1] [2] Foils are most easily made with malleable metal, such as aluminium, copper, [3] tin, and gold. Foils usually bend under their own weight and can be torn easily. [2] For example, aluminium foil is usually about 1 ⁄ 1000 inch (0.025 mm), whereas gold (more malleable than aluminium) can be made into foil only a few atoms thick, called ...
The history of materials science is the study of how different materials were used and developed through the history of Earth and how those materials affected the culture of the peoples of the Earth. The term " Silicon Age " is sometimes used to refer to the modern period of history during the late 20th to early 21st centuries.
Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
Foil made from a thin leaf of tin was commercially available before its aluminum counterpart. [2] In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminum foil. [3]
