Iyini i-6061 Aluminium Alloy?

Izakhiwo Zomzimba ze-6061 Aluminium

Uhlobo lwe-6061 i-aluminium ingeye-6xxx aluminium alloys, ehlanganisa lezo zingxube ezisebenzisa i-magnesium ne-silicon njengezici eziyinhloko ze-alloying.Idijithi yesibili ibonisa izinga lokulawula ukungcola kwe-aluminium eyisisekelo.Uma le nombolo yesibili ingu-"0", ibonisa ukuthi inqwaba ye-alloy iyi-aluminium yezohwebo equkethe amazinga ayo okungcola akhona, futhi akukho ukunakekelwa okukhethekile okudingekayo ukuze kuqiniswe izilawuli.Idijithi yesithathu neyesine zingabaklami bengxubevange ngayinye (qaphela ukuthi akunjalo ngamaalloyi e-aluminium angu-1xxx).Ukwakheka okulinganiselwe kohlobo lwe-aluminium engu-6061 ngu-97.9% Al, 0.6% Si, 1.0%Mg, 0.2%Cr, kanye no-0.28% Cu.Ukuminyana kwe-6061 aluminium alloy ngu-2.7 g/cm3.I-6061 aluminium alloy iyelapheka ngokushisa, yakheka kalula, ikwazi ukushiselwa, futhi ikwazi ukumelana nokugqwala.

Izakhiwo Zemishini

Izakhiwo zikagesi ze-6061 aluminium alloy ziyahluka ngokuya ngokuthi iphathwa kanjani ukushisa, noma yenziwa yaqina kusetshenziswa inqubo yokushisisa.Imodulus yayo yokunwebeka ingu-68.9 GPa (10,000 ksi) futhi i-shear modulus yayo ingu-26 GPa (3770 ksi).Lawa manani alinganisa ukuqina kwengxubevange, noma ukumelana nokuguquguquka, ungawathola kuThebula 1. Ngokuvamile, le ngxubevange kulula ukuyihlanganisa ngokushisela futhi igugeke kalula ibe yibunjwa obufunwa kakhulu, iyenze ibe yimpahla yokukhiqiza ehlukahlukene.

Izinto ezimbili ezibalulekile lapho ucubungula izakhiwo zemishini amandla esivuno namandla okugcina.Amandla esivuno achaza inani eliphezulu lokucindezeleka elidingekayo ukuze kukhubazeke ngokunwebeka kwengxenye ohlelweni olunikeziwe lokulayisha (ukushuba, ukucindezelwa, ukusonteka, njll.).Amandla amakhulu, ngakolunye uhlangothi, achaza inani eliphezulu lokucindezeleka into engakwazi ukumelana nayo ngaphambi kokuphuka (ukwenziwa ngepulasitiki, noma ukuwohloka unomphela).I-6061 aluminium alloy inamandla okukhiqiza angama-276 MPa (40000 psi), namandla okugcina e-tensile angu-310 MPa (45000 psi).Lawa manani afinyezwa kuThebula 1.

Amandla e-shear amandla okwenza okuthile ukumelana nokugundwa amabutho aphikisayo endizeni, njengoba nje isikelo sisika ephepheni.Leli nani liwusizo ekusetshenzisweni kokuguquguquka (ama-shafts, ama-bar njll.), lapho ukusonta kungabangela lolu hlobo lokucindezeleka kokugunda kokubalulekile.Amandla okushear we-6061 aluminium alloy ngu-207 MPa (30000 psi), futhi lawa manani afinyezwa kuThebula 1.

Amandla okukhathala yikhono lempahla yokumelana nokuphuka ngaphansi kokulayisha okujikelezayo, lapho umthwalo omncane unikezwa ngokuphindaphindiwe kokubalulekile ngokuhamba kwesikhathi.Leli nani liwusizo ezinhlelweni zokusebenza lapho ingxenye ingaphansi kwemijikelezo yokulayisha ephindaphindayo njengama-ekseli emoto noma amaphistoni.Amandla okukhathala we-6061 aluminium alloy ngu-96.5 Mpa (14000 psi).Lawa manani afinyezwa kuThebula 1.

Ukumelana Nokugqwala

Uma kuvezwe emoyeni noma emanzini, ingxubevange ye-aluminium engu-6061 yenza ungqimba lwe-oxide oluyenza ingasasebenzi nezinto ezigqwala kunsimbi engaphansi.Inani lokumelana nokugqwala lincike ezimweni zomoya/zamanzi;kodwa-ke, ngaphansi kwamazinga okushisa asendaweni, ukubola ngokuvamile akunakwa emoyeni/emanzini.Kubalulekile ukuqaphela ukuthi ngenxa yokuqukethwe kwethusi kwe-6061, imelana kancane nokugqwala kunezinye izinhlobo ze-alloy (njenge5052 aluminium ingxubevange, elingenayo ithusi).I-6061 inhle kakhulu ekulweni nokugqwala kwe-nitric acid egxilile kanye ne-ammonia ne-ammonium hydroxide.

Izicelo ze-Type 6061 Aluminium

Thayipha i-aluminium engu-6061 ingenye yama-alloys e-aluminium asetshenziswa kakhulu.Ikhono lokushisela nokwakheka kwayo kuyenza ifanelekele izinhlelo eziningi zenhloso ejwayelekile.Amandla ayo aphezulu kanye nokumelana nokugqwala kubolekisa uhlobo lwe-6061 alloy oluwusizo ikakhulukazi ekwakhiweni kwezakhiwo, kwesakhiwo, nasezimotweni.Uhlu lwayo lokusetshenziswa luphelele, kodwa ezinye izinhlelo zokusebenza ezinkulu ze-6061 aluminium alloy zihlanganisa:
