Aluminium nqi yog trending me ntsis upward xyoo no; Txawm li cas los xij, nyob rau lub sijhawm no, tus nqi yog nyob rau lub sijhawm luv luv sideways. tariffs thiab mov kev txhawj xeeb nyob rau hauv thiab yuav tsum txuas ntxiv txhawb tus nqi.

Axles yog Syntace 12mm thru-axles nrog flush haum bolts, thiab tom qab, tib cov xov siv los tiv thaiv lub qag kuj ruaj ntseg derailleur hanger rau hauv tus ncej. Tag nrho cov cables thiab hoses yog nyob rau hauv txoj kev thiab lub thav duab yog sib xws nrog tag nrho cov tam sim no pawg nyob rau hauv kev ua lag luam. Muaj lub rooj zaum yooj yim sab nraud thiab ib yam li UP, thiab lub rooj zaum lub raj lub kaum sab xis tau tsim nyob ib ncig ntawm xoom-offset 27.2mm lub rooj zaum ncej. Lub BB386EVO hauv qab bracket yog sib xws nrog txhua txoj kev cranksets. 

Lub tshuab muaj default arc pib nqis rau 3/32-nti tungsten, tab sis yog tias koj tsis tu ncua siv ib txoj kab uas hla sib txawv, koj tuaj yeem hu-hauv lub tshuab kom tailor koj arc pib raws li qhov xav tau. Koj tuaj yeem hloov AC waveform, xaiv ntawm Advanced Square, Soft Square, Daim duab peb sab, thiab Sine Wave. Kuv tau pom tias qhov chaw pib ua haujlwm zoo heev rau kuv, tab sis koj tuaj yeem sim nrog cov chaw no yog tias koj xav tau. Daim duab peb sab waveform khaws cov cua sov ntawm qhov qis tshaj plaws, nrog cov txiaj ntsig zoo tshaj plaws pom ntawm cov hlau nyias.

Vim muaj kev siv ntau dua ntawm cov pav ca-dov aluminium hauv kev lag luam tsheb, cov khoom siv ntawm cov hlau semi-tiav tau loj hlob nruj hauv Asmeskas kev lag luam. Kev siv cov txhuas hauv cov tsheb yuav zoo li nce ntxiv vim qhov xav tau rau cov neeg tsim khoom siv tsheb hloov mus rau 2025 Corporate Average Fuel Economy (CAFE) cov qauv kev lag luam roj. Qee cov kab tsheb ntxiv, tshwj xeeb tshaj yog cov khoom muag muag ntau dua, tuaj yeem hloov mus rau txhuas "dawb lub cev." Rau 2018, Ford Expedition thiab Lincoln Navigator tam sim no kuj siv txhuas lub cev.

Kuv tau siv cov aluminium brazing rods rau xyoo thiab lawv tau zoo heev rau me me fittings & kho.

Q: Kuv muaj ib qhov project uas yuav tsum tau vuam 6061-T6 extrusion rau lawv tus kheej thiab rau 6061-T6 daim ntawv. Kuv tus kws tshaj lij vuam hauv zos hais tias kuv tuaj yeem siv 4043 lossis 5356 muab tub lim hlau, tab sis qhov no tsis tsim nyog rau kuv. Tsis yog 5356 muaj zog dua?

Thiab tom qab ntawd muaj cov neeg zoo li kuv uas muaj dc tigged ally siv flux (tsis yog solder flux lol flux rau roj vuam ally) thiab lo alu rods (flux coated) nws ntxhov tab sis ua kom huv txaus tsim muaj zog weld ntawm cov nyiaj txiag txom nyem. Kuv yuav tsum hais tias thaum zoo prepped ib co ntawm cov aluminium brasing rods yog impressive heev.

Qhov kub thiab txias nyob ntawm cov ntaub ntawv sib nqus ntawm CoL4 tau piav qhia hauv daim duab 2. Lub sijhawm zoo sib nqus μeff pib ntawm tus nqi ntawm 4.50 μB ntawm chav tsev kub, uas yog qhov muaj txiaj ntsig ntau dua li tus nqi spin-tsuas yog S = 3/2 thiab g. = 2.0 (μeff/μB = 3.87) raws li qhov tseem ceeb ntawm kev koom tes ntawm lub orbital angular momentum rau hauv av. Lub μeff/μB pib txo qis ntawm qhov txias hauv qab 30 K mus txog tus nqi ntawm 3.62 ntawm T = 1.9 K, uas yog tshwm sim los ntawm xoom-field splitting (ZFS). Tib qhov tshwm sim kuj yog lub luag haujlwm rau qhov sib txawv loj ntawm isothermal magnetization curves ntsuas ntawm T = 2 thiab 5 K txog 5 T los ntawm theoretical Brillouin txoj haujlwm (Fig. 2). Raws li qhov tshwm sim ntawm DFT suav, peb tuaj yeem xav txog Co(II) atoms magnetically zoo sib cais los ntawm ib leeg thiab peb tuaj yeem siv kev nyab xeeb ntawm spin Hamiltonian formalism rau monomeric complex los txhais cov ntaub ntawv sim ntawm CoL4 raws li hauv qab no24.

Ob qhov ntsuas kub thiab qhov chaw nyob ntawm cov ntaub ntawv magnetization tau haum ib txhij nrog lub hom phiaj kom tau txais cov txiaj ntsig tsis zoo thiab nws tau pom tias qhov haum haum twb tau txais thaum rhombic anisotropy tsis saib xyuas. Raws li qhov tshwm sim, qhov zoo tshaj plaws-haum tsis tau pom zoo li g = 2.27, D = -10.1 cm−1 thiab χTIP = 5.3 ⋅10−9 m3mol−1 (Fig. 2), qhov twg χTIP stands rau kev pab ntawm qhov kub thiab txias. paramagnetism.24

Williamson tau hais tias lub nroog tau txuag tau $ 1.9 lab los ntawm kev hloov qee yam ntawm cov qauv tsim ntawm lub tsev. Lub ru tsev yuav yog galvanized steel es tsis txhob siv lub ru tsev aluminium, uas txuag tau txog $ 260,000. Tus neeg cog lus kuj tau pom zoo tso qee cov nqi nyiaj siv ua haujlwm thiab ua haujlwm siv hluav taws xob tsis yog ntiav tus neeg ua haujlwm sub.

Qhov thib peb, tus nqi nyiaj txiag qis dua ib xyoos ib zaug vim muaj peev txheej ntau dua. Kev taw qhia tus paj laum rau lub xyoo tseem zoo ib yam ntawm 8.2%, 8.5% ntau yam raws li tau qhia ua ntej, tuaj yeem pib qis dua yog tias qhov paj laum tau yooj yim me ntsis.

Txhawm rau kom txuag tau kev ntxhov siab thiab roj, lub iav thib tsib ncaws tawm thaum ntxov, tab sis tseem muaj ntau qhov oomph ntawm tus kais uas Merc ntawm steroids yuav nce siab ntawm qhov taw qhia 327km / h, uas yog tag nrho cov luv luv 2.65: 1 qag tso cai. Qhov ntawd tsis txaus kom tsim nyog rau Guinness World Records tab sis nws muaj ntau los qhia tias nws muaj lub siab tawv thiab kev pom thaum raug thawb mus rau qhov txwv.
