Aluminium, raws li cov khoom siv dav tshaj plaws hauv kev ua kis las, muaj nws qhov zoo tshaj plaws ntawm qhov hnyav. While aluminum has low rigidity and strength, this can be compensated for by increasing the material density per unit volume, while maintaining a relatively low weight. Tsis tas li ntawd, txhuas yog pheej yig dua li lwm cov khoom siv siab- kawg siv hauv cov tsheb kauj vab. Cov txhuas siv nyob rau hauv siab -kawg ncej (6000 series, 7000 series) yog tib qib siab-qib txhuas siv hauv aerospace.
1. Aluminium muaj qhov tsis zoo ntawm cov hlau tsis muaj zog. Txhawm rau piav qhia qhov no, xav txog cov duab hauv qab no. Peb tuaj yeem pom meej meej tias cov hmoov txhuas txhuas tau yooj yim punctured, thaum lub txiv hmab txiv ntoo hlau tuaj yeem nyob twj ywm. Kev tuag tsis muaj zog ntawm aluminium tsheb kauj vab yog tias ntau lub caij tsheb kauj vab caij tsheb kauj vab, qhov siab dua qhov kev ntxhov siab dhau los, thiab lub zog hloov pauv ntau. Tsis ntev los no, nyob rau hauv kev nrhiav lub teeb yuag, ntau thav duab yog ua los ntawm cov ntaub ntawv nyias (mus rau qhov siab). Cov thav ntawv no yog tsim los ntawm kev siv aluminium alloys yam tsis muaj kev qaug zog, uas yog vim li cas aluminium thav duab tuaj yeem kav ntev li 2-3 xyoos nyob rau hauv kev siv cov xwm txheej.
2. Aluminium tsis muaj elasticity thiab tsis tuaj yeem nqus kev co thaum caij tsheb. Hardtail thav duab ua los ntawm txhuas xa cov feem ntau ntawm kev vibrations ncaj qha mus rau tus neeg caij lub cev. Qhov no ua rau aluminium thav duab heev bumpy thiab tsis xis nyob rau caij. Ob qhov kev tsis zoo no ua rau txhuas tsis haum rau cov khoom siv tawv tawv. Txawm li cas los xij, feem ntau XC sib tw thav ntawv siv aluminium alloys vim tias txhuas yog lub teeb yuag thiab, los ntawm kev kho cua sov thiab tubing thev naus laus zis, tuaj yeem ua tiav lub zog siab, ua rau muaj kev sib tw zoo heev (kev sib tw kev ua tau zoo, ntawm chav kawm, tsis xav txog kev nplij siab los yog khoom lifespan). Tag nrho - tsheb kauj vab ncua tsis muaj cov kev txwv no. Nrog rau kev ywj pheej damping qauv kom nqus tau cov kev vibrations, ua ke nrog thicker thiab softer handlebars thiab eeb, aluminium tsis muaj elasticity yog kiag li neutralized. Tsis tas li ntawd, aluminium qhov hnyav dua tso cai rau qhov loj dua tubing cross-sections thiab localized reinforcement qhov twg xav tau lub zog. Yog li ntawd, aluminium yog ib yam khoom uas paub tab thiab txhim khu kev qha, thiab nws muaj qhov zoo hauv kev tsim khoom puv - ncua kev kawm ntawv.
