7075 ndi 7050 onse ndi ma aluminiyamu amphamvu kwambiri omwe amagwiritsidwa ntchito kwambiri muzamlengalenga ndi ntchito zina zofunika. Ngakhale amagawana zofanana, amakhalanso ndi kusiyana kwakukulu:
Kupanga
7075 aluminium alloyimakhala ndi aluminium, zinki, mkuwa, magnesium, ndi zina za chromium. Nthawi zina amatchedwa alloy-grade alloy.
Chemical Composition WT(%) | |||||||||
Silikoni | Chitsulo | Mkuwa | Magnesium | Manganese | Chromium | Zinc | Titaniyamu | Ena | Aluminiyamu |
0.4 | 0.5 | 1.2-2 | 2.1-2.9 | 0.3 | 0.18-0.28 | 5.1-5.6 | 0.2 | 0.05 | Zotsalira |
7050 aluminium alloyilinso ndi aluminiyamu, zinki, mkuwa, ndi magnesiamu, koma imakhala ndi zinc zambiri poyerekeza ndi 7075.

Mphamvu
7075 imadziwika ndi mphamvu zake zapadera, zomwe zimapangitsa kuti ikhale imodzi mwazitsulo zolimba kwambiri za aluminiyamu zomwe zilipo. Ili ndi mphamvu yapamwamba kwambiri komanso mphamvu zokolola poyerekeza ndi 7050.
7050 imaperekanso mphamvu zabwino kwambiri, koma nthawi zambiri imakhala ndi mphamvu zochepa poyerekeza ndi 7075.
Kukaniza kwa Corrosion
Ma alloys onsewa ali ndi kukana kwa dzimbiri, koma 7050 ikhoza kukhala ndi kukana kwabwinoko pang'onopang'ono kusweka kwa dzimbiri poyerekeza ndi 7075 chifukwa cha kuchuluka kwake kwa zinc.
Kukaniza Kutopa
7050 nthawi zambiri imawonetsa kukana kutopa bwino poyerekeza ndi 7075, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito pomwe kutsitsa kwapang'onopang'ono kapena kupsinjika mobwerezabwereza kumakhala nkhawa.
Weldability
7050 ali weldability bwino poyerekeza 7075. Ngakhale aloyi onse akhoza welded, 7050 zambiri sachedwa akulimbana ndi kuwotcherera njira.
Mapulogalamu
7075 imagwiritsidwa ntchito kwambiri m'mapangidwe a ndege, njinga zamoto zogwira ntchito kwambiri, mfuti, ndi ntchito zina pomwe chiŵerengero champhamvu ndi kulemera ndi kulimba ndikofunikira.
7050 imagwiritsidwanso ntchito pazamlengalenga, makamaka m'malo omwe mphamvu zambiri, kukana kutopa, komanso kukana dzimbiri zimafunikira, monga mafelemu a fuselage a ndege ndi ma bulkheads.
Kuthekera
Ma alloys onsewa amatha kupangidwa, koma chifukwa cha mphamvu zawo zazikulu, amatha kupereka zovuta pakukonza. Komabe, 7050 ikhoza kukhala yophweka pang'ono pamakina poyerekeza ndi 7075.
