7075 Urugendo rwa Aluminium

7075 urupapuro rw'aluminium ni iy' Al{1}}Inyuma-Mg -Cu super- Ibarabara ry'aluminium y'ivyuma vy'imbere (ivy'igihugu GB/T 3190), birimwo 5.6% Zn, 2.5% Mg na 1.6% C. Inyuma y’ubuvuzi bwa T6, inkomezi zirashobora gushika *560MPa canke zirenga** (ubugoyagoye HB kuruta canke bungana na 150), ivyo bikaba ari kimwe mu bigereranyo bikomeye kuruta ibindi vyose mu bikorwa vy’ubudandaji vy’ubudandaji. Inkomezi zayo zihariye ni nziza kuruta ivyuma, ariko ubushobozi bwayo bwo gusenyuka buragoyagoya, kandi ikeneye kurindwa mu gutera ivyatsi canke gutera aluminium. Ikoreshwa cane cane mu muzigo urengeje urugero- gutera imbere nk’ibice vy’imibumbe y’indege, ibihimba vy’imizinga, n’ibikoresho vyinshi - ibikoresho. Ni ngombwa kwitwararika impengamiro yo gusenyuka kw’imibabaro mu gihe co gukora. Ni vyiza ko umuntu akomeza mu gukura inyuma y’umuti w’imbere ya - umwotsi (O state).

Kubera inkomezi zayo z’ivyuma (T6 inkomezi z’ugukomera cane kuruta canke zingana na 560MPa) n’inkomezi nziza cane, 7075 urupapuro rw’aluminium rukoreshwa cane cane muri:

1. Aeropace: urukoba rw’indege, ibisasu vya misile, ibihimba vy’imiterere y’inyenyeri n’ibindi bintu nyamukuru - ibihimba;

2. Ibikoresho vy’igisirikare: isahani yo gukingira imodoka zifise ibirwanisho, ibirwanisho vy’intwaro, n’ibindi;

3. High- ibimenyetso: ibikoresho vyo gutera urushinge, ibipfukisho, n’ibindi;

4. Amabara: Ivyiyumviro vy’uguhagarara kwa F1, imiterere y’umubiri w’uburemere buke;

5. Imashini y’ugushinga: hejuru- gushiramwo ivyicaro, ivyuma vy’amazi, n’ibindi.

Ikeneye gukorana n’uburyo bwo gupfuka canke bwo gupfuka aluminium kugira ngo ishobore gutera imbere, kandi ni co kintu gikundwa ku bidukikije vy’ubuhinga bikomeye cane.

Ivyuma vyacu vy’aluminiyumu 7075 ahanini birungikwa hanze mu turere twateye imbere mu nganda muri Amerika y’Uburaruko, mu Buraya no muri Aziya, harimwo na Leta Zunze Ubumwe za Amerika, Ubudage, Ubuyapani na Koreya y’Epfo. Aya masoko manini manini-ang afise ibisabwa bikomeye ku bijanye n’ibikorwa vy’ibikoresho kandi akoreshwa cane mu kirere, ibikoresho vya gisirikare, ibikoresho vy’ugubumbabumba n’ibice vy’amarushanwa. Twarashizeho uruhererekane rw’ibikoresho vyo mu mahanga biciye mu kwizera uburyo bihuye n’icemezo mpuzamakungu nka ASTM, AMS na EN, kandi dushobora gushitsa ivyo abakiriya bakeneye cane mu turere dutandukanye ku masahani y’ivyuma vy’agaciro kanini.

7075 amabara y’aluminium akorwa hakoreshejwe ubuhinga buteye imbere bw’ivyuma vy’ivyuma vy’ivyuma, n’igipimo c’ibintu vy’ivyuma nk’ivyo bita zinc, magnesium n’umuringa bigenzurwa neza kugira ngo ivyo bikoresho bishike ku mico y’ubuhinga. Ivyo bipande birashuha - bishizweko ubupfumu, bikonje- vyashizweko kugira ngo birangire, hanyuma bikomezwa n’ugusukura kw’ubushuhe (T6 state) n’ugukura kw’ugukura kw’ibintu. Dukoresha ibikoresho vyo gupima neza kugira ngo tugenzure ukuntu amasahani ameze neza, n’ukwihanganira ±0.1mm, kandi dukoresha ubuhinga bwo kugerageza butagira - ubuhinga bwo gupima nk’ugutahura amakosa y’amajwi kugira ngo tubone uburyo bwo mu mutima, gutanga uburinzi bwo kwizigirwa ku bikorwa vy’ubuhinga bwa none.

7075 urupapuro rw’aluminium rushobora gutanga inyishu zitandukanye z’ubuhinga bwo kuvura ku ruhande, harimwo no guhindura cane (gukora igice kinini c’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma (ivy’ivyuma vy’ubuhinga bwa none) n’ivy’umusenyi (ivy’ugufatanya kw’ivyuma vy’ivyuma). Ku bijanye n’ivyo guhonyanga {{3} =} dushobora gutanga ubuvuzi bwa Aladge canke Teflon kugira ngo dushobore gushitsa ibisabwa n’uguhungabana kw’ibidukikije vy’igisirikare n’ivy’amazi. Ubuvuzi bwose bwo ku butaka buratanga igenzura rikomeye ry'uburyo nk'ibipimo vy'umunyu kugira ngo bimenyekane ko bihuye n'ingingo mfatirwako mpuzamakungu nk'i MIL{5}}A-8625.
