Imirongo 7 ya aluminiyumu ni Al-Zn-Mg-Cu, Amavuta yakoreshejwe mu nganda zikora indege kuva mu mpera za 1940. Uwiteka7075 aluminiyumuifite imiterere ihamye kandi irwanya ruswa ikomeye, ninziza nziza yindege hamwe namasahani yo mu nyanja. Kurwanya ruswa isanzwe, ibintu byiza bya mashini hamwe na reaction ya anode.

Ibinyampeke byiza bikora neza cyane gucukura no kongera imyambarire. Imbaraga nziza za aluminiyumu ni 7075, ariko ntishobora gusudwa, kandi irwanya ruswa irashobora kuba mibi cyane, ibice byinshi bya CNC bikata inganda zikoresha 7075. Zinc nikintu nyamukuru kivanze muri uru ruhererekane, hiyongereyeho amavuta ya magnesium make arashobora gutuma ibikoresho bivurwa nubushyuhe, kugirango bigere kumbaraga zikomeye cyane.

Uru ruhererekane rw'ibikoresho muri rusange rwongewe ku gipimo gito cy'umuringa, chromium n'ibindi bivangwa, kandi muri byo harimo umubare wa 7075 aluminiyumu ya aluminiyumu ni ubuziranenge bwo hejuru, imbaraga zisumba izindi, zikwiranye n'indege n'ibikoresho bikomeye.Ibiranga ni, plastike nziza nyuma yo kuvura igisubizo gikomeye, imbaraga zo kuvura ubushyuhe nibyiza cyane, ifite imbaraga nyinshi munsi ya 150 and, kandi ifite imbaraga zubushyuhe buke cyane; imikorere mibi yo gusudira; guhangayikishwa no kwangirika; isize aluminiyumu cyangwa ubundi buryo bwo kuvura. Gusaza kabiri birashobora kunoza uburyo bwo guhangana na alloy stress ruswa. Plastike muri anneale kandi yazimye gusa iri munsi gato ya leta imwe ya 2A12. byiza gato kurenza 7A04, isahani ihagaze umunaniro. Gtch iroroshye, kwangirika kwimyitwarire iruta 7A04. ubucucike ni 2,85 g / cm3.

7075 aluminiyumu ifite imiterere yubukanishi, imikorere yihariye mubice bikurikira:

1. imbaraga nyinshi: Imbaraga zingana za 7075 aluminiyumu irashobora kugera kuri 560MPa, ikaba ari ibikoresho byimbaraga nyinshi za aluminiyumu, bikubye inshuro 2-3 iyindi miti ya aluminiyumu mubihe bimwe.

2. Gukomera kwiza: Igipimo cyo kugabanuka nigice cyo kurambura 7075 ya aluminiyumu ya aluminiyumu ni ndende cyane, kandi uburyo bwo kuvunika ni ukuvunika gukomeye, bikwiranye no gutunganya no gukora.

3. Imikorere myiza yumunaniro: 7075 Aluminiyumu irashobora gukomeza kugumana imiterere yubukanishi munsi yumuvuduko mwinshi hamwe nuburemere bwisubiraho, nta okiside, kumeneka nibindi bintu.

4. gukora neza cyane mukubungabunga ubushyuhe:7075 AluminiyumuIrashobora kugumana imiterere myiza yubukanishi mubushyuhe bwo hejuru, ni ubwoko bwubushyuhe bwo hejuru burwanya aluminiyumu.

5. Kurwanya ruswa neza: 7075 Aluminiyumu ya aluminiyumu ifite imbaraga zo kurwanya ruswa kandi irashobora gukoreshwa mugukora ibice bifite ibyangombwa byinshi byo kurwanya ruswa.

Imiterere ：

1.O-leta: (leta yometse)

Uburyo bwo kubishyira mu bikorwa: Shyushya aluminiyumu 7075 ku bushyuhe bukwiye, ubusanzwe kuri dogere selisiyusi 350-400, komeza igihe runaka hanyuma ukonje buhoro buhoro ubushyuhe bwicyumba, intego: gukuraho imihangayiko yimbere no kunoza plastike nubukomezi ibikoresho.Imbaraga ntarengwa zingana na 7075 (7075-0 ubushyuhe) ntizishobora kurenga 280 MPa (40.000 psi) nimbaraga zitanga umusaruro mwinshi wa MPa 140 (21,000 psi). Kurambura ibikoresho (kurambura mbere yo gutsindwa kwa nyuma) ni 9-10%.

2.T6 (kuvura gusaza):

Uburyo bwo kubishyira mu bikorwa: uburyo bwa mbere bwo gukemura igisubizo ni ubushyuhe bwo gushyushya kugeza kuri dogere selisiyusi 475-490 no gukonjesha byihuse hanyuma kuvura gusaza, mubisanzwe kuri dogere selisiyusi 120-150 kumasaha menshi, intego: kunoza imbaraga nubukomezi bwibikoresho .Imbaraga zidasanzwe za T6 ubushyuhe 7075 ni 510.540 MPa (74,00078.000 psi) n'imbaraga zitanga byibuze MPa 430.480 (63,00069.000 psi). Ifite kunanirwa kwagura 5-11%.

3.T651 (kurambura + gusaza gukomera):

Uburyo bwo kubishyira mu bikorwa: hashingiwe ku gukomera kwa T6 gusaza, igice runaka cyo kurambura kugirango ukureho imihangayiko isigaye, intego: gukomeza imbaraga nyinshi no gukomera mugihe utezimbere plastike nubukomezi.Imbaraga zidasanzwe za T651 ubushyuhe 7075 ni 570 MPa (83,000) psi) n'imbaraga z'umusaruro wa 500 MPa (73.000 psi). Ifite kunanirwa kuramba kwa 3 - 9%. Ibiranga birashobora guhinduka bitewe nuburyo bwibikoresho byakoreshejwe. Isahani yimbitse irashobora kwerekana imbaraga nke no kuramba kuruta imibare yavuzwe haruguru.

Ikoreshwa nyamukuru rya 7075 aluminium:

1.Umwanya wo mu kirere: 7075 aluminiyumu ikoreshwa cyane mubijyanye n’ikirere kubera imbaraga nyinshi n'ibiranga uburemere. Bikunze gukoreshwa mugukora indege, amababa, imitwe myinshi nibindi bice byingenzi, kimwe nizindi nzego zisaba imbaraga nyinshi no kurwanya ruswa.

2. inganda zitwara ibinyabiziga: 7075 ya aluminiyumu nayo igira uruhare runini mu gukora imodoka. Bikunze gukoreshwa muri sisitemu yo gufata feri na chassis ibice byimodoka zikora cyane hamwe nimodoka zo gusiganwa, kugirango tunoze imikorere yimodoka no kugabanya ibiro.

3. ibikoresho by'imyitozo ngororamubiri: Bitewe n'imbaraga nyinshi n'ibiranga uburemere, 7075 ya aluminiyumu ikoreshwa mu gukora ibikoresho bya siporo, nk'ibiti byo gutembera, clubs za golf, n'ibindi.

4. kubaka imashini: Mu rwego rwo gukora imashini, 7075 ya aluminiyumu nayo ikoreshwa cyane mugukora ibice byuzuye, ibishushanyo nibindi. Byongeye kandi, 7075 ya aluminiyumu ikoreshwa cyane muguhuha plastike (icupa), gusudira kwa ultrasonic plastike yo gusudira, inkweto, impapuro za pulasitike, ifuro ikora ifuro, ibishashara, icyitegererezo, ibikoresho, ibikoresho bya mashini, gutunganya ibumba nizindi nzego. Irakoreshwa kandi mugukora ama-aluminium alloy yamagare yamagare.

Twibuke ko nubwo i7075 aluminiyumuifite ibyiza byinshi, biracyakenewe kwitondera imikorere idahwitse yo gusudira hamwe nuburyo bwo guturika kwangirika, bityo aluminiyumu cyangwa ubundi buryo bwo kuvura birashobora gukenerwa gukoreshwa.

Muri rusange, amavuta ya aluminiyumu 7075 afite umwanya wingenzi mubikorwa byinshi byinganda kubera imikorere myiza kandi ikoreshwa neza.
