Aluminium alloy tshav kub kho code
Pharma Aluminium alloy kev kho cua sov code raws li nram no
F: Dawb machining xeev (muaj feem xyuam rau cov khoom uas tsis muaj kev tshwj xeeb rau kev ua hauj lwm hardening thiab kev kho cua sov thaum lub sij hawm molding txheej txheem, cov khoom siv kho tshuab ntawm cov khoom hauv lub xeev no tsis tau teev tseg)
O :Annealed mob (rau cov khoom tiav tag nrho annealed rau yam tsawg kawg nkaus lub zog)
H : Ua hauj lwm hardening xeev (muaj feem xyuam rau cov khoom uas nws lub zog yog nce los ntawm kev ua hauj lwm hardening. Tom qab ua haujlwm hardening, cov khoom tuaj yeem tau txais kev kho cua sov ntxiv kom txo tau lub zog. H code yuav tsum ua raws li ob lossis peb tus lej Arabic)
W: Cov tshuaj kho lub xeev (lub xeev tsis ruaj khov, tsuas yog siv tau rau cov alloys uas muaj hnub nyoog ib txwm nyob ntawm chav tsev kub tom qab kev kho cua sov, lub xeev txoj cai no tsuas yog qhia tias cov khoom yog nyob rau hauv lub ntuj aging theem)
T : Kev kho cua sov hauv xeev (muaj feem xyuam rau cov khoom uas tau ua hauj lwm hardened mus rau ib tug ruaj khov lub xeev tom qab kev kho cua sov)
T1: dag dag
T2: Annealed
T4: kev kho mob + ntuj aging
T5: Kev kho mob + tsis tiav kev laus kev laus
T6: kev kho mob + ua tiav kev laus kev laus
T7: Kev kho mob + kev kho mob stabilization
T8: Lub xeev ntawm kev ua haujlwm txias thiab kev laus kev laus tom qab kev daws teeb meem
T9: Lub xeev ntawm kev laus kev laus tom qab kev daws teeb meem, thiab tom qab ntawd ua haujlwm txias
