Aoyin 7075 ipu alumini e faʻatatau i se faʻaoga masani i le 7-series alumini alumini. E masani ona faʻaaogaina i vaega tipi CNC, talafeagai mo vaʻa vaʻalele ma mea faʻaoga maualuga. O le 7-series alumini alumini e iai le Zn ma le Mg. O le Zinc o le elemene autu lea e faʻapipiʻi i lenei faasologa, o lea e lelei tele le teteʻeina o le corrosion, ma o sina vaega itiiti o le magnesium alloy e mafai ona oʻo atu ai le mea i se malosi maualuga pe a maeʻa togafitiga vevela.

O le 7-series alumini alumini o se Al-Zn-Mg-Cu alumini sili-malosi. O lenei u'amea na fa'aaogaina i le gaosiga o vaalele i le tuai o 1940s ma o lo'o fa'aaogaina lautele i le va'alele. O loʻo faʻaalia i le palasitika lelei pe a maeʻa togafitiga fofo, aemaise lava le lelei o le vevela togafitiga faʻamalosia aafiaga, malosi maualuga i lalo ole 150 °C, ma aemaise lava le malosi maualalo maualalo; le lelei uelo; fa'amamafa le malepelepe matele; e manaʻomia ona faʻapipiʻiina i le alumini poʻo isi puipuiga faʻaogaina e faʻaaogaina. Lua-laasaga matua faʻaleleia atili le gafatia o le faʻapipiʻi e teteʻe atu i le faʻalavelave faʻafefe. O le palasitika i le tulaga faʻafefe ma tineia e laʻititi laʻititi nai lo le tulaga tutusa o le 2A12. E sili atu nai lo 7A04, 7075 ipu alumini vaivai static. Notch ma'ale'ale, fa'avevesi fa'a'ele'ele fa'atinoga e sili atu nai lo le 7A04. Ole mamafa ole 2.85g/cm3.
