1. Dab tsi yog qhov siab tshaj plaws lub zog aluminium alloy?
Cov Khoom Siv Tseem Ceeb:
Muaj cov zinc raws li kev ua thawj cov khoom siv ua ntej (nrog rau cov magnesium me me thiab tooj liab).
Ua tiav qhov kawg tensile lub zog (UTS) ntawm~ 572 MPa (83, {2}} psi)Hauv T651 Tauj (kub - kho thiab ntxhov siab - Relieved).
Siv nyob rau hauv Aerospace (cov dav hlau txheej txheem sib xyaw ua ke, tsaws iav), siab - kev ua tau zoo machinery, thiab khoom siv kis las (piv txwv li, lub kauj vab sib tw).
Tsab ntawv: Ntau dua - lub zog alloys muaj (piv txwv li, {{1} {1}} t3 rau cov ntawv qhia tshwj xeeb) rau lub zog rau tag nrho lub zog.
2. Qhov xim twg ntawm txhuas yog qhov zoo tshaj?
Tej nyiaj \/ nws yog xim hlau:
Txheem tiav rau cov nqaij nyoo lossis zeb - ua tiav txhuas.
Qhia cov hlau lub ntsej muag zoo nkauj thiab siv nyob rau hauv architectural trim, cookware, thiab hniav zoo nkauj.
Anodized xim:
Anodizing ntxiv cov txheej oxide cov roj thiab xim (piv txwv li, dub, tooj dag, liab, xiav).
Qhov zoo tshaj plaws rau corrosion tsis kam thiab zoo nkauj(piv txwv li, cov rooj tog sab nraum zoov, cov khoom siv hluav taws xob, tsheb trim).
Pleev xim \/ Txheej xim:
Hmoov txheej lossis ntub xim muaj cov xim muaj kuab heev, xim sib txawv.
Siv nyob rau hauv kev tsim kho (txhuas siding, Windows) rau UV tiv taus thiab tsim qauv.
Tag: Tsis muaj cov thoob ntiaj teb "zoo tshaj plaws" xim-xaiv raws li kev xav tau (corrosion tsis kam, cua sov dissipation) lossis tsim cov hom phiaj.
3. Yuav ua li cas los xaiv aluminium qib?
Spark kuaj: Pom cov qauv dag thaum sib tsoo cov hlau (tsis muaj kev ntseeg tau rau cov qhab nia zoo).
Tensile kuaj: Ntsuas lub zog thiab ductility kom phim cov txheej txheem alloyoy.
X - Tshav fluorescence (XRF): Siv cov cuab yeej Portable los tshawb xyuas lub chaw ua hluav taws xob sai sai.
los ntawm cov ntaub ntawv thiab cov qauv
Txheeb cov ntawv pov thawj cov chaw tsim khoom, zeb cav, lossis cov khoom siv tshwj xeeb (piv txwv li, ASTM, ISO cov qauv).
4. Tus twg txhuas qib yog pheej yig tshaj?
Becume cov no muaj cov ntsiab lus alloy tsawg (cov nqi ua kom tsawg).Mos, ductile, thiab yooj yim rau daim ntawv, ua rau lawv zoo tagnrho rau kev fabrication yooj yim.
Kev Lag Luam-Offs:
Tsawg zog piv rau lwm yam alloys.
Tsis haum rau load - cov kabmob lossis kev siv siab - kev ntxhov siab.
5. Yuav ua li cas xyuas txhuas alloy?
Kev kuaj pom thiab kho tshuab
Kev tshwm sim: Saib rau mill cov cim, nyiaj muas, lossis ntawv cim qhia txog Alloy (piv txwv li, "6061" ntawm extruded profiles).
Hlau Nplej Xeem: Aluminium yog tsis yog - sib nqus, yog li cov hlau nplaum yuav tsis lo (pab tau kom paub qhov txawv ntawm cov hlau, tab sis tsis yog rau kev muab qhab nia).
Kev ntsuas hardness: Siv aRockwell lossis Brinell Hardness TesterTxhawm rau sib piv cov txiaj ntsig tawm tsam Alloy qauv.
Tshuaj Lom
Xrf spectroscopy: Muab cov khoom lag luam tam sim ntawd (zinc, magnesium, tooj liab, thiab lwm yam) kom phim alloy cov qib.
Kev kuaj: Xa cov qauv rau kev sib txuas lus ntshav ntshav (ICP)
Kev kho cua sov thiab kev ntsuas kub
Paub meej txog qhov npau taws (piv txwv li T4, T6) los ntawm kev txheeb xyuas cov khoom siv tau tawm los lub zog thiab elongation zog tiv thaiv industRy cov qauv (piv txwv li, Astm B221).
