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 ...
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 Nigeria can be traced to the earliest inhabitants whose date remains at least 13,000 BC through the early civilizations such as the Nok culture which began around 1500 BC. Numerous ancient African civilizations settled in the region that is known today as Nigeria, such as the Kingdom of Nri , [ 1 ] the Benin Kingdom , [ 2 ] and ...
[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 ...
Metal Foil Deep Etching is a plastograph print in which aluminium foil is used to draw the engraved images. The thin foil is cut and placed on an engraved plate and then the embossed sheet is removed, turned over and filled with resin to stabilise the relief. The resin filled foil is then laminated on plywood or no any other surface.
Metal leaf, a very thin sheet of decorative metal; Aluminium foil, a type of wrapping for food; Tin foil, metal foil made of tin, the direct predecessor to aluminium foil; Transparency (projection), a thin sheet of transparent flexible material, placed on an overhead projector for display to an audience
Other similar materials are composed of aluminium-titanium, or titanium-amorphous silicon, are used for joining materials by reactive bonding. Other similar intermetallic compositions used in pyrotechnics are titanium-boron and aluminium-palladium ("Pyrofuze"). These foils are made in a range of thicknesses, e.g. 60, 80, 100, and 150 micrometers.
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.
