IiPropati zoBume be6061 Aluminiyam
Uhlobo6061 aluminiyamyeye-6xxx yealloyi ye-aluminiyam, ebandakanya loo mixube esebenzisa i-magnesium kunye ne-silicon njengezona zinto ziphambili zokuhlanganisa. Idijithi yesibini ibonisa iqondo lokulawula ukungcola kwisiseko se-aluminium. Xa le nombolo yesibini "0", ibonisa ukuba ubuninzi be-alloy yi-aluminium yorhwebo equkethe amanqanaba ayo okungcola akhoyo, kwaye akukho nkathalo ekhethekileyo efunekayo ukuze kuqiniswe ulawulo. Idijithi yesithathu neyesine ngabayili bealloyi nganye (qaphela ukuba akunjalo nge-1xxx ialluminiyamu alloys). Ukubunjwa okuqhelekileyo kohlobo lwe-6061 aluminium ngu-97.9% Al, 0.6% Si, 1.0% Mg, 0.2% Cr, kunye ne-0.28% Cu. Ubuninzi be-6061 i-aluminium alloy yi-2.7 g / cm3. I-6061 i-aluminiyam ialloy iyanyangeka, yenziwe lula, iyakwazi ukushibilika, kwaye ilungile ekuxhathiseni ukubola.
IiPropati zoomatshini
Iimpawu ze-6061 ze-aluminium alloy ziyahluka ngokusekelwe kwindlela ephathwa ngayo ubushushu, okanye yenziwe yomelele ngokusebenzisa inkqubo yokufudumala. Imodyuli yayo ye-elasticity yi-68.9 GPa (10,000 ksi) kunye nemodyuli yayo yokucheba yi-26 GPa (3770 ksi). Ezi xabiso zilinganisa ukuqina kwe-alloy, okanye ukuchasana ne-deformation, unokufumaneka kwiThebhile 1. Ngokuqhelekileyo, le ngxube ilula ukudibanisa ngokudibanisa kwaye iguqule ngokukhawuleza kwiimilo ezinqwenelekayo, iyenze ibe yimathiriyeli yokuvelisa izinto ezininzi.
Izinto ezimbini ezibalulekileyo xa kuqwalaselwa iipropati zoomatshini ngamandla esivuno kunye namandla okugqibela. Amandla esivuno achaza ubuninzi boxinzelelo olufunekayo ukuguqula i-elastically inxalenye kwilungiselelo lokulayisha elinikeziweyo (uxinzelelo, ukunyanzeliswa, ukujija, njl.). Amandla okugqibela, ngakolunye uhlangothi, achaza ubuninzi boxinzelelo lwezinto eziphathekayo ezinokumelana nazo ngaphambi kokuphuka (ukwenza iplastiki, okanye ukuguqulwa okusisigxina). I-6061 i-aluminium alloy inamandla e-tensile ye-276 MPa (40000 psi), kunye namandla okugqibela e-310 MPa (45000 psi). La maxabiso ashwankathelwa kwiThebhile yoku-1.
Amandla okucheba kukukwazi kwesixhobo ukuxhathisa ukuchetywa yimikhosi echasayo ecaleni kwenqwelomoya, kanye njengokuba isikere sinqumla ephepheni. Eli xabiso liluncedo kwizicelo ze-torsional (i-shafts, imivalo njl.), apho ukujija kunokubangela olu hlobo loxinzelelo lokucheba kwizinto eziphathekayo. Amandla e-shear ye-6061 ye-aluminium alloy yi-207 MPa (30000 psi), kwaye ezi xabiso zishwankathelwa kwiThebhile 1.
Amandla okukhathala yikhono lezinto eziphathekayo zokumelana nokuphulwa phantsi komthwalo we-cyclical, apho umthwalo omncinci unikezelwa ngokuphindaphindiweyo kwizinto eziphathekayo ngexesha. Eli xabiso liluncedo kwizicelo apho inxalenye ixhomekeke kwimijikelo yokulayisha ephindaphindiweyo efana ne-axles yesithuthi okanye ipistons. Amandla okukhathala kwe-6061 i-aluminium alloy yi-96.5 Mpa (14000 psi). La maxabiso ashwankathelwa kwiThebhile yoku-1.

Ukunyangwa kokuMhlwa
Xa ibonakaliswe emoyeni okanye emanzini, i-6061 i-aluminiyam ialloy yenza umaleko we-oxide eyenza ukuba ingasebenzi kunye nezinto eziphazamisayo kwintsimbi engaphantsi. Ubungakanani bokunganyangeki komhlwa kuxhomekeke kwiimeko zomoya/amanzi; nangona kunjalo, phantsi kobushushu be-ambient, iziphumo ezinobungozi azinakwanga emoyeni/emanzini. Kubalulekile ukuqaphela ukuba ngenxa yomxholo wobhedu we-6061, iyancipha kancinci kwi-corrosion kunezinye iintlobo ze-alloy (njenge5052 ingxubevange aluminiyam, engenanto yobhedu). I-6061 ilungile ngokukodwa ekuxhathiseni umhlwa kwi-asidi ye-nitric egxininisiweyo kunye ne-ammonia kunye ne-ammonium hydroxide.
Usetyenziso lwe-Aluminium yoHlobo lwe-6061
Uhlobo lwe-6061 aluminiyam yenye yezona zinto zisetyenziswa kakhulu i-aluminium alloys. Ukubanako kwayo ukuwelda kunye nokwakheka kwenza ukuba ilungele izicelo ezininzi zenjongo jikelele. Amandla ayo aphezulu kunye nokumelana nomhlwa iboleka uhlobo lwe-6061 ialloy eluncedo ngakumbi kuyilo, ulwakhiwo, kunye nokusetyenziswa kwemoto. Uluhlu lwayo lokusetyenziswa luphelele, kodwa ezinye izicelo eziphambili ze-6061 aluminium alloy ziquka:
