Alloys yog hlau nrog cov khoom siv txhim khu kev qha (lub zog, hluav taws xob ua haujlwm, kev ua haujlwm, thiab lwm yam) ua los ntawm kev ntxiv cov khoom siv hlau rau hauv cov hlau, thiab cov koob no muaj npe tom qab plaub tus lej. 3003 aluminium alloy thiab 6061 aluminium alloy yog ob tus qauv nrov, qhov txawv ntawm lawv yog dab tsi?
1. Cov khoom tseem ceeb thiab kev siv ntawm 3003 thiab 6061
3003 txhuas yog nyob rau hauv 3xxx series, uas txhais tau hais tias nws lub ntsiab alloying ntsiab yog manganese, nws muaj ib tug zoo tiav, nws muaj zoo formability, nws welds zoo, nws yog nruab nrab muaj zog thiab resistant rau corrosion. Hais txog tib yam li ntshiab txhuas, tsis muaj tshuaj tiv thaiv rau cov txheej txheem kho cua sov. Hloov chaw, cov hlau no tuaj yeem ua kom tawv tawv kom nws lub zog thiab feem ntau yog tempered hauv 3003-H18 thiab 3003-H22. Thaum tsis muaj zog tshwj xeeb, 3003 txhuas muaj ntau daim ntawv thov hauv cov khoom noj khoom haus / tshuaj lom neeg ua lag luam ua cov khoom siv tsis zoo tsis tau xeb.
Zoo li lwm yam 6xxx alloys, 6061 txhuas muaj magnesium thiab silicon raws li nws cov ntsiab lus alloying, uas yog lub luag haujlwm rau nws lub zog zoo. 6061 txhuas ua tau zoo dua lub zog nce thaum kho cua sov thiab muaj ntau hauv T6 thiab T4 tempers. Nws tuaj yeem pom nyob rau hauv ntau lub khw muag khoom thiab yog thawj qhov kev xaiv rau kev sib dhos vuam, lub tsev thav duab, lossis ib qho qauv uas yuav tsum muaj pob zeb-khoom pob txha.
