Aluminium thiab Aluminium Alloy xeev code (GB / T16475-2008)
GB / T16475 stipulates uas txhuas lub xeev cov lis dej num yog sawv cev rau cov lej tseem ceeb los yog cov tsiaj ntawv hauv xeev tseem ceeb lossis cov tsiaj ntawv Askiv kev kho mob lossis kev kho mob tshwj xeeb uas cuam tshuam cov yam ntxwv khoom {}}
Tus lej "x" hauv piv txwv cov lej sawv cev rau ib qho xwm txheej Arabic, xws li "H2X" tuaj yeem sawv cev rau ib qho xwm txheej ntawm "H2X", "H22 ~ H294", lossis "H224 ~ H394"; "-" sawv cev rau ib qho kev tsis raug cai ntawm cov lej Arabic lossis tus lej, xws li "t6151, T6151, T6151, T7651, thiab lwm yam {18}
Rooj 1 Lub Xeev Txoj Cai, Npe, Cov Lus Qhia thiab Ntawv Thov
| Txoj cai | Lub npe | Nqe lus piav qhia thiab ntawv thov |
| F | Dawb Ua Xeev | Applicable to products with no special requirements for work hardening and heat treatment conditions during the molding process. No provisions are made for the mechanical properties of products in this state |
| O | Annealed xeev | Muaj feem xyuam rau cov khoom lag luam uas tau txais lub zog yam tsawg kawg nkaus tom qab puv annealing |
| H | Ua Haujlwm Lub Xeev Hardening | Muaj feem xyuam rau cov khoom lag luam uas ua kom muaj zog los ntawm kev ua haujlwm hnyav |
| W | Kev daws teeb meem kub kho lub xeev | Muaj feem xyuam rau lub xeev uas tsis ruaj khov ntawm cov laus ntawm chav sov tom qab kev kho mob lub xeev, tab sis tsuas yog qhia tias cov khoom lag luam yog nyob hauv kev laus theem |
| T | Kev kho cua sov lub xeev sib txawv los ntawm f 0 lossis h | Muaj feem rau lub xeev ruaj khov tom qab daws kev kho mob kub nrog (lossis tsis muaj) ua haujlwm tawv |
Cov Lus 2 Ntu Kev Qhia Txog Lub Xeev Ib Leeg
| Txoj cai | Lub npe | Nqe lus piav qhia thiab ntawv thov |
| O1 | Qeeb Cua Txias Tom Qab Kev Kub Ntxawg Kub | Muaj feem xyuam rau lub xeev uas cov khoom lag luam lossis cov qauv yog cov khoom siv kub zoo sib xws thiab muab tso rau hauv cov khoom siv kub ua ntej, thiab nws feem ntau tsis yog qhov kev xa tawm zaum kawg ntawm cov khoom |
| O2 | Kev kho thermomechanical | Muaj feem rau lub xeev uas tus neeg siv aneals cov khoom lag luam ntawm kev kho kub (rau qhov kub kho kom sov) ua ntej kev kho mob kom tau txais kev kho kom zoo |
| O3 | Homogenization Xeev | Muaj feem rau qhov kub tshaj anealing xeev ntawm nruam casting cov hlau txuas lossis tshem tawm cov hlua khi lossis txo cov kab sib cais thiab pab txhawb kev txuas ntxiv Kuv deformation |
Rooj 3 lub xeev sawv cev los ntawm thawj tus lej tom qab h
Thawj tus lej tom qab h indicates lub xeev: nws qhia tias cov txheej txheem yooj yim kom tau txais lub xeev, sawv cev los ntawm 1 ~ 4 |

| Txoj cai | Lub npe | Nqe lus piav qhia thiab ntawv thov |
| H1X | Ua kom dawb huv lub xeev-hardening lub xeev | Muaj feem xyuam rau lub xeev uas xav tau lub zog tuaj yeem tau txais los ntawm kev ua haujlwm-hardening tsis muaj kev kho cua sov ntxiv |
| H2X | Lub xeev tsis tiav annealing hauv lub xeev tom qab ua haujlwm-hardening | Muaj feem xyuam rau cov khoom lag luam uas muaj kev ua haujlwm hnyav tshaj qhov uas tau ua tiav ntawm cov khoom siv kub uas tsis tiav ntawm cov khoom siv kub tsis tiav thaum muaj txiaj ntsig H3X; rau lwm cov alloys muaj tib yam li cov tense tensile muaj zog raws li tus coj H1X lub xeev, tab sis lub elongation ib nyuag siab dua H1X |
| H3X | Stabilization xeev tom qab ua haujlwm-hardening | Muaj feem xyuam rau cov khoom lag luam uas tau poob qis-kub kev kho mob tom qab ua haujlwm-hardening lossis nws cov khoom siv tau mus txog kev ruaj ntseg vim muaj cua sov ua haujlwm |
| H4X | Xim (txheej) kev kho mob lub xeev tom qab ua haujlwm-hardening | Muaj feem xyuam rau cov khoom lag luam uas tau ua tiav tsis tiav kev kawm tom qab ua haujlwm-hardening vim xim (txheej) kho |
