7xxx akatevedzana maaruminiyamu mahwendefa anozivikanwa nekusarudzika kwesimba-kusvika-huremu reshiyo, zvichiita kuti ive sarudzo yepamusoro yemaindasitiri anoita zvemhando yepamusoro. Mugwaro iri, isu tichaputsa zvese zvaunoda kuziva nezve iyi alloy mhuri, kubva mukuumbwa, machining uye mashandisiro.
Chii chinonzi 7xxx Series Aluminium?
The7xxx akatevedzana aluminium alloy ndeyekumhuri ye zinc-magnesium alloy (se7075, 7050, 7475), yakanyatsogadzirirwa zvinhu zvine simba guru. Core features zvinosanganisira:
Main ingredients: zinc (5-8%) + magnesium + mhangura.
Kurapa Kupisa: Magiredhi mazhinji ane kupisa kupisa (T6/T7 kutsamwa) kwekuwedzera kusimba.
Simba: Kusimba simba kusvika ku570 MPa (kupfuura simbi zhinji).
Ongorora: Corrosion kuramba yakadzikira zvishoma pane 6 akateedzana aruminiyamu alloy (coating kudzivirira).
7075 ndiyo yakajairika 7xxx akateedzana aruminiyamu alloy, iwo hunhu hukuru isimba rakawanda, kusimba kuneta kwakanyanya, kushandiswa kwakajairika iaviation furemu, midziyo yemauto, nezvimwe.
Chikonzero chekusarudza a7-yakatevedzana aluminium alloy ndiro
Ultra-Yakakwirira Simba: Yakanakira zvinhu zvinotakura zvinhu.
Kureruka: 1/3 iyo density yesimbi.
Heat Resistance: Inochengetedza zvivakwa panzvimbo yakakwirira tembiricha.
Machinability: Inowana kushivirira kwakasimba nemidziyo yakakodzera.

Tool Selection
Zvishandiso zvekucheka: Carbide kana polycrystalline diamond (PCD) zvishandiso.
Tool Geometry: High rake angles (12°–15°) kuderedza kupisa.
Lubrication: Shandisa mhute inotonhorera kuderedza kukwesha.
Kurumidza & Feed Recommendations
Kugaya: 800–1,200 SFM (tsoka dzepamusoro paminiti).
Kuchera: 150-300 RPM ine peck drilling kujekesa machipisi.
Dzivisa Chatter: Chengetedza mahwendefa ane vacuum zvigadziriso.
Post-Machining Care
Stress Relief: Anneal zvikamu kudzivirira warping.
Anodizing: Isa Type II kana III anodizing yekudzivirira ngura.
Matambudziko Anowanikwa & Mhinduro
Stress Corrosion Cracking:
Chikonzero: Residual stress + nharaunda dzine hunyoro.
Gadzirisa: Shandisa T73 kutsamwa, shandisa machira ekudzivirira.
Galling Panguva Yekutengesa:
Chikonzero: Yakakwira zinc yemukati.
Gadzirisa: Shandisa matepi akavharidzirwa; zora nemafuta anorema-basa.
Pamusoro Zvikumbiro zve7xxx Aluminium Plates
Aerospace: Wing spars, giya rekumhara.
Defence: Armored motokari zvikamu.
Mitambo: mafuremu ebhasikoro, midziyo yekukwira.
Motokari: High-stress injini zvikamu.
