Lub aluminium alloy muaj qhov ntom ntom ntom, tab sis lub zog siab, ze lossis ntau tshaj cov hlau tsis zoo, cov khoom siv yas zoo, tuaj yeem ua tiav rau hauv ntau cov ntawv qhia, muaj cov hluav taws xob zoo heev, cov thermal conductivity thiab corrosion kuj. Nws yog dav siv nyob rau hauv kev lag luam thiab siv thib ob yog rau hlau.
Qee cov hlau alloys tuaj yeem kho kub kom ua tiav cov tshuab zoo, lub cev lub cev thiab tiv thaiv corrosion. Tawv aluminium alloy belongs rau AI-Cu-Mg system, feem ntau muaj me me ntawm Mn, uas tuaj yeem kho cov cua sov thiab ua kom muaj zog. Nws yog tsiag ntawv los ntawm siab hardness tab sis plasticity tsis. Superhard aluminium yog Cu-Mg-Zn system, tuaj yeem kho cov cua sov thiab ua kom muaj zog. Nws yog lub zog siab tshaj plaws aluminium alloy nyob rau hauv chav tsev kub, tab sis muaj kev tiv thaiv tsis zoo corrosion thiab siab kub muag muag.
Zinc alloys yog alloys raws li zinc thiab ntxiv rau lwm yam ntsiab lus. Hom kev qhia ntxiv alloying muaj xws li cov khoom siv hluav taws xob tsawg tsawg zinc alloys xws li txhuas, tooj liab, magnesium, cadmium, txhuas, thiab titanium. Zinc alloy muaj tsawg melting taw tes, fluidity zoo, yooj yim fusion vuam, ua kom tawg thiab yas kev ua haujlwm. Nws muaj peev xwm tiv taus xeb hauv cov huab cua, thiab cov khib nyiab pov tseg yog yooj yim kom rov zoo thiab rov ua dua; tab sis creep lub zog yog tsawg, thiab nws yog qhov yooj yim rau kev hloov pauv los ntawm kev laus dhau los. Npaj los ntawm yaj, tuag nrum lossis lub siab txheej txheem rau hauv cov khoom siv. Raws li cov txheej txheem tsim khoom, nws tuaj yeem faib ua cam khwb cia zinc alloy thiab deformed zinc alloy.
Lub ntsiab lus ntxiv ntawm zinc alloy yog txhuas, tooj liab thiab magnesium. Zinc alloy tuaj yeem faib ua ob hom: deformation thiab cam khwb cia zinc alloy raws li kev siv tshuab ua. Cov txhuas zinc alloy muaj fluidity zoo dua thiab tiv taus corrosion.
1. Cov ntsiab lus tseem ceeb.
2. Cov yeeb yaj kiab ua haujlwm tau zoo, thiab qhov ua tau zoo meej nrog cov duab nyias thiab cov phab ntsa nyias yuav raug tuag-qhov haujlwm, thiab saum npoo ntawm cov casting yog du.
3. Kev kho deg: electroplating, txau, pleev xim, thawm, sib tsoo, thiab lwm yam.
4. Tsis muaj cov hlau tsis nqus tau thaum lub sijhawm melting thiab tuag casting, tsis muaj kev txhim kho corrosion, thiab tsis muaj pwm rau siv.
5. Muaj cov cuab yeej zoo hauv tshuab thiab hnav tsis kam thaum sov li chav nyob.
6. Tsawg melting taw tes, yaj ntawm 385 ° C, tuag yooj yim tuag.
