7 mndandanda Aluminiyamu alyoy ndi al-zn-cg-cu, theryoy wagwiritsidwa ntchito mu ndege zopanga ndege kuyambira kumapeto kwa zaka za m'ma 1940. A7075 aluminiyamu aloyAli ndi mawonekedwe olimba ndi kukana kwamphamvu kuvunda, komwe ndikofunikira kwambiri pa ndege zam'madzi komanso kutchuka kwam'madzi.

Mbewu zabwino zimapanga bwino kwambiri magwiridwe antchito ndikuwonjezera kuvala. Mphamvu zabwino kwambiri za aluminiyam alloy ndi alonto 7075, koma sangathe kuwuzidwa, ndipo kukana kwawo kuvunda ndi osauka kwambiri, omwe amapanga zigawo zambiri za CNC. Zinc ndi chinthu chachikulu cha Aloya mu mndandanda uno, kuphatikiza kwenikweni magnesium alloy angathandize kuti zinthu zitheke kutentha, kufikira mphamvu zapamwamba kwambiri.

Zinthu zingapo izi zimawonjezeredwa kwa mkuwa, chromium ndi ena omwe ali, ndipo omwe nambala ya 7075 aluminiyamu imakhala yabwino kwambiri, mphamvu yayikulu kwambiri, Mapulasitiri abwino pambuyo pa njira yolimba ya mankhwala, kutentha kwa kutentha kumakhala kovuta makamaka, kumakhala ndi mphamvu kwambiri. kupsinjika kuwononga chizolowezi; zophika alumininum kapena chithandizo china choteteza. Kukalamba kawiri kumatha kusintha kukana kwa alloy kupsinjika kumasokoneza. Mapulasitiki a dziko lokhazikika ndipo amangongokhala pang'ono pang'ono kuposa momwe asanu aliwonse a 2a12. bwino kuposa 7a04, mbale yambiri. GTCH ndiovuta, kupsinjika kwa kupsinjika kuli bwino kuposa 7A04. Kuchulukitsa ndi 2.85 g / cm3.

7075 Aluminiyam Alloy ali ndi katundu wabwino kwambiri, magwiridwe apadera motsatira izi:

1. Mphamvu yayikulu: Mphamvu ya aluminiyamu ya 7075 aluminium alloy imatha kufikira zoposa 560MPA, zomwe zimakhala zamphamvu kwambiri za aluminiyamu slominiyamu pazomwezi.

2. Kulimba kwabwino: Gawo la Shringge ndi kukula kwa ememiniyamu eloy ndiokwera, ndipo mawonekedwe a kusokonekera ndi kuwonongeka kwamphamvu, komwe kuli koyenera kukonza ndikupanga.

3. Kuwonongeka kwabwino kwabwino: 7075 aluminium aloy kumatha kukhalabe ndi mphamvu zake pamakina omwe ali ndi nkhawa kwambiri komanso kubereka katundu, popanda oxidation, kusweka ndi zochitika zina.

4. Kugwiritsa ntchito bwino chitetezo:7075 aluminiyamu aloyimatha kukhalabe ndi mphamvu yake yamakina kutentha kwambiri, yomwe ndi mtundu wa kutentha kwambiri kosagwirizana ndi aluminiyamu.

Mkhalidwe:

1.O-State: (State Stat)

Njira Yokwaniritsa: Yambitsani aluminiyamu 707 aluminiyamu chiloya chotentha, nthawi zambiri pa nthawi ya 350-400 Celsius, kusunga kwa nthawi kenako kuzizira kwa kutentha kwa chipinda, cholinga: kuthetsa kupsa mtima kwa ma pulasitiki ndi kulimba kwa zakuthupi. Mphamvu yayikulu kwambiri ya 7075 (7075-0) sadzapitilira 280 sempa (40,000 ppa (40,000 ppa (40,000 ppa (40,000 ppa (40,000 ppa (40) psi). Kukula kwa zinthuzo (kutambalala musanayambe kulephera komaliza) ndi 9-10%.

2.T6 (Kulaula):

Njira yokwaniritsira: Njira yoyamba yothetsera njira ndi yolumikizana mpaka 475-490 madigiri a Celsius ndi nthawi yayitali, nthawi zambiri kumadola, nthawi zambiri ku Celsius Celsius Celsius Celsius Slus . Mphamvu yayikulu kwambiri ya T6 Techperting 7075 ndi 510,540 MPA (74,00078,000 (74,00078,000 (74,00078,000 (74,00078,000) ndi mphamvu yokwanira 430,480 MPA (63,00069,000). Imakhala ndi kulephera kwa 5-11%.

3.Th1 (Kutambasulira ukalamba):

Njira yokwaniritsira: Pamaziko aukalamba, gawo lina lomwe limatambasula kuti muchepetse nkhawa zotsalira, cholinga chachikulu ndikulimbana ndi mpweya wa T651 ndi wa 570 MPA (88,000 PSI) ndi mphamvu yokwanira ya 500 MPA (73,000 psi). Imakhala ndi kulephera kwa 3 - 9%. Makhalidwe awa amatha kusinthidwa malinga ndi mawonekedwe a zomwe zagwiritsidwa ntchito. Mphete zakumapeto zitha kuonetsa mphamvu zotsika komanso zoyambira kuposa manambala omwe alembedwa pamwambapa.

Kugwiritsa Ntchito Kwambiri kwa 7075 Aluminium Aloy:

1.Aerospace munda: 7075 Aluminium aloy amagwiritsidwa ntchito kwambiri m'munda wa Aeroslossece chifukwa cha mphamvu zake zazikulu komanso zopepuka. Nthawi zambiri imagwiritsidwa ntchito popanga mapiko a ndege, mapiko, mapiko opukutira ndi zigawo zina zazikulu, komanso magulu ena omwe amafunikira nyongolotsi zazikulu ndi kukana.

2. Makampani autotive: The 7075 aluminiyamu iloy imagwiranso ntchito yofunika pakupanga magalimoto. Nthawi zambiri imagwiritsidwa ntchito pobowola ndi ma chassis a magalimoto oyenda kwambiri komanso magalimoto othamanga, kuti apititse patsogolo magalimoto ndikuchepetsa thupi.

3. Zida zolimbitsa thupi;

4. Mnyumba yamakina: Pamunda wa kupanga makina, 7075 aluminiyamu alloy amagwiritsidwanso ntchito kwambiri popanga magawo, nkhungu ndi zina zotero. Kuphatikiza apo, 7075 aluminium aloy amagwiritsidwanso ntchito kwambiri pakuwombera pulasitiki (botolo laulemu, nkhungu Amagwiritsidwanso ntchito popanga ma aluminium a aluminiyamu njinga.

Tiyenera kudziwa kuti ngakhale7075 aluminiyamu aloyAli ndi zabwino zambiri, ndikofunikirabe kusamala ndi kusachita kwake kosautsa bwino komanso chizolowezi chopsinjika kuwononga, kotero kuti mankhwala ena a aluminiyamu kapena chitetezo china chingafunike kugwiritsa ntchito.

Mwambiri, alnoy wa 7075 aluminiyamu ali ndi malo ofunikira m'minda yambiri ya mafakitale chifukwa cha ntchito yake yabwino kwambiri komanso kugwiritsa ntchito kwakukulu.
