Joaloka morekisi ea ka sehloohong oa lihlahisoa tsa aluminium le lits'ebeletso tsa machining tse nepahetseng, re hlokomela bohlokoa ba ho khetha thepa e nepahetseng bakeng sa lits'ebetso tse batlang. Har'a lisebelisoa tse phahameng tsa aluminium tse sebetsang hantle,Litepisi tsa aluminium tsa 2019tsoa e le khetho ea premium e etselitsoeng maemo a feteletseng. Sengoliloeng sena se shebana le sebopeho sa metallurgical, litšobotsi tsa mochini, le lits'ebeliso tse fapaneng tsa poleiti ea aluminium ea 2019, e fanang ka leseli ho thusa baenjiniere le litsebi tsa ho reka thepa ho etsa liqeto tse nepahetseng.
Sebopeho sa Lik'hemik'hale: Saense e ka Morao ho Aluminium ea 2019
Aluminium ea 2019 ke motsoako o entsoeng oa letoto la 2000 (lelapa la aluminium-copper). Sebopeho sa eona se lokisoa hantle ho fihlela tekanyo e nepahetseng pakeng tsa matla, machinability, le botsitso ba mocheso. Lintlha tsa bohlokoa tsa alloying li kenyelletsa:
Koporo (Cu): 5.2% ~ 6.8% E matlafatsa matla le karabelo e thata ea pula.
Magnesium (Mg): 0.25% ~ 0.7% E ntlafatsa bokhoni ba ho thatafatsa khatello le botsitso ba mocheso.
Manganese (Mn): 0.4% ~ 1.0% E laola sebopeho sa lijo-thollo le boitšoaro bo bocha.
Tšepe (Fe): ≤0.30% E laoloa e le litšila ho boloka ductility.
Silicon (icon (Si): ≤0.25% E laoloa ho qoba mekhahlelo e kotsi ea intermetallic.
Zirconium (Zr) le Titanium (Ti): Lekola lipalo bakeng sa ntlafatso ea lijo-thollo le litšobotsi tse ntlafetseng tsa ho chesa.
Alloy hangata e fanoa ka T3, T6, kapa T8 tempers, e bonts'ang tharollo ea mocheso, ho tima, le botsofali ba maiketsetso ho eketsa thepa ea mochini.
Thepa ea Mechini le 'Mele: Tlaleho ea Ts'ebetso e Phahameng
Poleiti ea aluminium ea 2019 e bonts'a karo-karolelano e ikhethang ea matla ho isa ho boima, e fetang li-alloys tse ngata tse tloaelehileng ka ho tiea le mamello ea tšenyo. Mehaho e tloaelehileng ea mochini (bakeng sa T851 temper) e kenyelletsa:
Ultimate Tensile Strength (UTS): ≥62 ksi (427MPa)
Tensile Yield Strength (TYS): ≥42 ksi (290MPa)
Elongation nakong ea khefu: ≥10% (ka lisenthimithara tse 2)
Matla a Shear: ~34 ksi (234MPa)
Matla a Mokhathala: E ntle haholo tlas'a maemo a cyclical loading.
Litšobotsi tsa eona tsa 'mele li boetse li totobatsa ho tšoaneleha ha eona bakeng sa boenjiniere bo tsoetseng pele:
Boima: 0.101 lb/in³ (2.80 g/cm³)
Melting Range: 935℉~1180°F (502℃~638°C)
Thermal Conductivity: 121 W/m·K
Ts'ebetso ea Motlakase: ~34% IACS
Haholo-holo, 2019 e bonts'a machinability e ntle, e lekantsoeng ho 80% ha e bapisoa le litekanyetso tsa litšupiso tsa 2011-T3 alloy. E boetse e boloka botsitso ho pholletsa le mocheso o pharalletseng, e hanela deformation ea creep tlasa khatello e tsitsitseng ea thermo-mechanical.
Kopo: Tšimo ea bokhabane ba poleiti ea aluminium ea 2019
Ka lebaka la profaele ea eona e matla ea ts'ebetso,2019 poleiti ea aluminium e boletsoengliindasteri tse ngata tse phahameng:
1. Aerospace & Defense: E sebelisoa ka likhopo tsa mapheo, liforeimi tsa fuselage, le lisebelisoa tsa lisebelisoa tsa ho lulisa ka lebaka la ho thatafala ha eona ho phahameng le ho hanyetsa ho phatlalatsoa ha crack.
2. Peiso ea Likoloi: E loketse likhokahano tsa ho emisoa, li-chassis tse matlafatsang, le lisebelisoa tsa enjine moo ho leng bohlokoa ho fokotsa boima ba 'mele le ho thothomela.
3. Likoloi tsa Sesole: E sebelisoa meahong ea likoloi tse nang le lihlomo le lisistimi tsa borokho tse nkehang tse hlokang bots'epehi ba bolo ea maoto le ho monya ho ts'oenyeha.
4. Lisebelisoa tse nepahetseng: E loketse li-jigs, li-fixtures, le metheo ea hlobo e hlokang ho nepahala ha nako e telele ea geometri.
5. Mekhoa ea Tsamaiso ea Thermal: Coefficient ea eona e leka-lekaneng ea ho atolosa mocheso e lumellana le lijana tsa mocheso le lipoleiti tsa li-exchanger likarolong tse pholileng tsa avionics.
Ke Hobane'ng ha U ka Fumana Plate ea Aluminium ea 2019 ho Rona?
Re kopanya tiisetso e tiileng ea boleng (e netefalitsoeng ho AMS 4160 le ASTM B209) ka ho fana ka thepa ka nako le bokhoni ba ho etsa mochini oa CNC. Hore na o hloka ho fokotsa maemo a prototype kapa tlhahiso e felletseng, sehlopha sa rona sa tekheniki se netefatsa hore se latela lintlha tsa hau.
Ntlafatsa morero oa hau kaBokhoni ba aluminium plate ea 2019 bo ke keng ba bapisoa. Kopa khotheishene ea mahala le lintlha tsa setifikeiti kajeno. Ha re etseng katleho ea hau hammoho.
