Sayansi yotchuka: mitundu yosungunuka ya ma aluminiyamu aloyi

Mwachidule

Aluminiyamu ndi chitsulo chodabwitsa, chodziwika chifukwa cha kusinthasintha kwake, kutha ntchito, ndi katundu wopepuka. Ndi malo osungunuka omwe ndi okwera kwambiri kuti azitha kugwiritsidwa ntchito pazinthu zambirimbiri, n'zosadabwitsa kuti chinthu ichi ndi chachitatu chochuluka kwambiri mu kutumphuka kwa dziko lapansi ndi chitsulo chosagwiritsidwa ntchito kwambiri pambuyo pa chitsulo.. Mu positi iyi yabulogu, tifufuza malo osungunuka a aluminiyamu, zotsatira zake pamitundu yosiyanasiyana ya aluminiyamu, zinthu zomwe zimakhudza katundu wovuta kwambiri, ntchito zake, ndi momwe zimafananira ndi zitsulo zina.

aluminiyamu wosungunuka

Tchati cha Melting Point cha Aluminium Alloys

Malo osungunuka a aluminiyumu ndi chinthu chofunikira kwambiri chomwe chimakhudza kugwiritsidwa ntchito kwake m'mafakitale osiyanasiyana. Malo osungunuka a aluminiyamu yoyera ndi 660.32 ° C (1220.58°F). Komabe, pamene zinthu zina zimawonjezedwa kupanga zitsulo za aluminiyamu, malo osungunuka angasinthe. Zotsatirazi ndi tchati chosungunuka chamagulu asanu ndi atatu a ma aluminiyamu opangidwa mwachinyengo:

Mndandanda Melting Point (°C) Melting Point (°F)
1000 Series Aluminium 643 – 660 1190 – 1220
2000 Series Aluminium Alloy 502 – 670 935 – 1240
3000 Series Aluminium Alloy 629 – 655 1170 – 1210
4000 Series Aluminium Alloy 532 – 632 990 – 1170
5000 Series Aluminium Alloy 568 – 657 1060 – 1220
6000 Series Aluminium Alloy 554 – 655 1030 – 1210
7000 Series Aluminium Alloy 476 – 657 889 – 1220

Zindikirani: deta imachokera Matweb.

Magawo awa akuwonetsa kuti kuwonjezeredwa kwa ma alloying kumatha kusintha kwambiri malo osungunuka kuti agwirizane ndi ntchito zina.

Kusungunula kwa Ma Aluminiyamu Ofanana ndi Aloyi

Mitundu isanu ndi itatu yayikulu yopangidwa ndi aluminiyamu ya alloy ili ndi ma alloy omwe amagwiritsidwa ntchito kwambiri. Gome lotsatirali limasankha ena mwa iwo kuti awonetse malo osungunuka omwe amasungunuka:

Aloyi Model Mndandanda Melting Point (°C) Melting Point (°F)
1050 1000 646 – 657 1190 – 1210
1060 646.1 – 657.2 1195 – 1215
1100 643 – 657.2 1190 – 1215
2024 2000 502 – 638 935 – 1180
3003 3000 643 – 654 1190 – 1210
3004 629.4 – 654 1165 – 1210
3105 635.0 – 654 1175 – 1210
5005 5000 632 – 654 1170 – 1210
5052 607.2 – 649 1125 – 1200

Zinthu Zomwe Zimakhudza Kusungunuka kwa Aluminiyamu

Zinthu zingapo zimatha kukhudza kusungunuka kwa aluminiyumu ndi ma alloys ake:

  • Alloying Elements: Kukhalapo kwa alloying zinthu monga mkuwa, magnesium, silicon, ndipo zinki zimatha kukweza kapena kutsitsa malo osungunuka, kutengera kuyanjana kwawo ndi aluminiyamu.
  • Zonyansa: Ngakhale kuchuluka kwa zonyansa kumatha kusokoneza malo osungunuka. Mwachitsanzo, chitsulo, zomwe nthawi zambiri zimakhala ngati zonyansa, akhoza kuchepetsa malo osungunuka.
  • Mbiri Yotentha: Mbiri yotentha ya aluminiyamu, kuphatikiza mankhwala aliwonse am'mbuyomu otentha kapena kukonza, imatha kuwongolera kapangidwe kambewu ndikusokoneza malo osungunuka.
  • Njira Zopangira: Njira zosiyanasiyana zopangira, monga kulimbitsa mofulumira kapena zitsulo za ufa, Zitha kuyambitsa ma microstructures osalingana okhala ndi malo osungunuka osiyanasiyana.

Kugwiritsa ntchito Aluminium's High Melting Point

Malo osungunuka kwambiri a aluminiyumu ndi ma alloys ake amawapangitsa kukhala oyenera pamitundu yosiyanasiyana ya kutentha kwambiri.:

  • Welding ndi Brazing: Kusungunuka kwa aluminiyumu kumapangitsa kuti pakhale njira zolimba zowotcherera komanso zowotcherera, zomwe ndi zofunika pakupanga mapangidwe ovuta ndi zigawo zikuluzikulu.
  • Kutentha Kutentha: Kusungunuka kwapamwamba kwazitsulo zina za aluminiyamu zimawapangitsa kukhala abwino kuti azigwiritsidwa ntchito posinthanitsa kutentha, kumene angathe kupirira kutentha kwapamwamba kwa ntchito popanda kusungunuka.
  • Zophika: Kusungunuka kwambiri kwa aluminiyamu kumapindulitsanso popanga zophikira, kuwonetsetsa kuti mapoto ndi mapoto amatha kupirira kutentha kwambiri popanda kusungunuka.

Momwe Aluminiyamu Yosungunuka Imafananira ndi Zitsulo Zina

Poyerekeza ndi zitsulo zina, malo osungunuka a aluminiyamu si apamwamba. Pano pali kuyerekezera kwa zitsulo zosungunuka za aluminiyamu ndi zitsulo zina zochepa:

Chitsulo Melting Point (°C) Melting Point (°F)
Aluminiyamu 660.32 1220.58
Mkuwa 1085 1981
Chitsulo 1538 2800
Zinc 419 776
Chitsulo 1370 – 1520 (zimasiyanasiyana) 2502 – 2760 (zimasiyanasiyana)

Kuyerekeza uku kukuwonetsa kuti pomwe aluminiyumu imakhala ndi malo otsika osungunuka kuposa zitsulo monga chitsulo ndi chitsulo, ndi apamwamba kuposa zinki ndi zitsulo zina zambiri. Izi zimayika aluminiyumu pamalo abwino kwa mapulogalamu omwe amafunikira kukhazikika pakati pa kukana kutentha kwambiri ndi kutha ntchito.

Pomaliza, kusungunuka kwa aluminiyumu ndi chinthu chofunikira kwambiri chomwe chimakhudza kugwiritsidwa ntchito kwake m'mafakitale osiyanasiyana. Kumvetsetsa zinthu zomwe zimakhudza malowa komanso momwe zimafananira ndi zitsulo zina ndikofunikira pakusankha zinthu komanso kukhathamiritsa kwazinthu.. Malo osungunuka kwambiri a aluminiyumu, kuphatikiza ndi zina zake zothandiza, imapangitsa kukhala chinthu chosunthika chamitundumitundu yogwiritsira ntchito.
