WebAluminium foil (or aluminum foil in North American English; often informally called tin foil) is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is …

WebAluminium nitride (Al N) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) and is an electrical insulator. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies.

WebAluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown.However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international …

WebLes alliages d'aluminium pour fonderie sont des alliages dont le constituant principal est l'aluminium, destinés à être transformés par des techniques de fonderie.Ils sont souvent nommés « alliages légers » du fait de leur masse volumique nettement inférieure à celles d'autres métaux utilisés dans l'industrie.Ils sont à distinguer des alliages d'aluminium …

WebAluminium – glin o czystości technicznej, zawierający różne ilości zanieczyszczeń, zależnie od metody otrzymywania.W wyniku rafinacji elektrolitycznej otrzymuje się aluminium zawierające 99,950–99,955% Al. Aluminium hutnicze, otrzymywane przez elektrolizę tlenku glinu w stopionym kriolicie, zawiera 99,0–99,8% Al.. Nazwą systematyczną pierwiastka …

WebAluminium-26 (26 Al, Al-26) is a radioactive isotope of the chemical element aluminium, decaying by either positron emission or electron capture to stable magnesium-26.The half-life of 26 Al is 7.17 × 10 5 (717,000) years. This is far too short for the isotope to survive as a primordial nuclide, but a small amount of it is produced by collisions of atoms with cosmic …

Web3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 alloy, except for the addition of approximately 1% magnesium.It can be cold worked (but not, unlike some other types of aluminium alloys, heat treated) to produce tempers with a higher strength but a lower ductility.Like most …
