kirjeldus
7075 T651 Aluminium Plate or UNS A97075 aluminium plate is a type of Al-Zn-Mg-Cu super-hard aluminum alloy known for its exceptional high strength, kõvadus, and excellent mechanical properties. It also exhibits good anodic reactivity. The presence of chromium enhances its resistance to stress corrosion cracking, while zinc imparts strength comparable to that of steel.
7075 alumiinium Plaat (AA7075) is an aluminum alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, suur tugevus, sitkus, and good resistance to fatigue. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys. In fact, hinne 7075 aluminum is stronger than many types of mild steel.
7075-T651 alumiiniumplaati has nearly double the strength-to-weight of grade 2 titaan
7075 aerospace aluminum
The 7075 Al alloy is most preferred by the aircraft industry. The composition of this specific Al alloy is 5.1–6.1% zinc, 2.1–2.9% magnesium, 1.2–2.0% copper and less than 0.5% of silicon, raud, mangaan, titaan, chromium and other trace metals
One of the key reasons to consider 7075 alumiinium is for its high strength. Alloyed with zinc, it is one of the strongest alloys available and stronger than 6061. But it offers a lower level of corrosion resistance than 6061 and is also more difficult to weld. 7075 is used in marine, auto, and aerospace applications where strength is a very high priority. It is also used in a firearms manufacturing and is even used in hang glider frames
alumiinium Sheet / Plaati 7075-T6/T651 kasutatakse tavaliselt kosmosetööstuses, sõjaline, ja autotööstuse rakendused. 7075 alumiinium on tugevaim alumiinium, paljude teraste tugevusega, säilitades samal ajal alumiiniumi kerged omadused ja korrosioonikindluse.

alumiinium 7075 on liige 7000 seeria, mille peamiseks legeerivaks komponendiks on tsink ja mis on hästi tuntud oma erakordselt suure tugevuse poolest. Karastustöötlus võib seejärel veelgi suurendada selle suurt mehaanilist tugevust. See omadus teeb sulami 7075 väga populaarne lennundus- ja kaitsetööstuses.

Selle tugevus on võrreldav paljude terasetüüpide omaga, kuid sellel on palju väiksem tihedus. Sulam on suurepärane terase asendaja kõrge pingega rakendustes. Samuti talub see suurepäraselt väsimusstressi, muutes selle väga usaldusväärseks, kvaliteet, mida ülalnimetatud tööstusharudes väga otsitakse.
sulam 7075 pakub ainult keskmist korrosioonikindlust, selle keemilises koostises sisalduva väikese koguse vase tulemus. Sellel on ka mõistlik töödeldavus ning halb vormimine ja keevitatavus. Selle sulami teine puudus on see, et selle erakordselt kõrge tugevuse tõttu on selle hind võrreldes teiste alumiiniumisulamitega suhteliselt kõrge..
