Lokacin zabar kayan don gini, masana'antu, ko DIY ayyukan, aluminum da bakin karfe sune biyu daga cikin shahararrun mawuyacin karafa. Amma menene daidai yake banda su? Ko kai injiniya ne, mai saƙa, ko kawai m, fahimtar bambance-bambancen su na iya taimaka maka ka yanke shawara. A cikin wannan blog, za mu rushe dukiyoyinsu, aikace-aikace, farashi, da ƙarin goyon baya daga tushen ƙwararru - don taimaka muku zaɓi kayan da ya dace don bukatunku.
1. Abun ciki: Me ake yi da su?
Babban bambanci tsakanin aluminum da bakin karfe maƙaryata ne a cikin kayan aikinsu.
Goron ruwalokaci mai nauyi ne, ƙarfe-fari ne wanda aka samo a cikin ɓawon burodi a duniya. Bishiyar aluminum yana da taushi, don haka sau da yawa yana tare da abubuwan da yake da tagulla, magnesium, ko silicon don haɓaka ƙarfi. Misali, da aka yi amfani da aluminum mai amfani da 6061 alloy ya ƙunshi magnesium da silicon.
Bakin karfeParoy ne na baƙin ƙarfe wanda ke kunshe da ƙalla 10.5% chromium, wanda ke haifar da Layer mai sassaucin ra'ayi don tsayayya da lalata. Grades gama gari kamar 304 bakin karfe shima sun haɗa da nickel da carbon.
2. Ƙarfi da karko
Abubuwan da ake buƙata na ƙarfi sun bambanta ta aikace-aikace, don haka bari mu kwatanta abubuwan kayan aikin su.
Bakin karfe:
Bakin karfe yana da ƙarfi sosai fiye da aluminium, musamman ma a cikin yanayin damuwa. Misali, aji 304 bakin karfe yana da karfin tenesile na ~ 50 MPa, idan aka kwatanta da 6061 aluminum a ~ 310 MPa.
Alumum:
Duk da yake ƙasa da ƙarfi ta girma, aluminium yana da mafi kyawun nauyin nauyi-da-nauyi. Wannan ya sa ya zama cikakke ga kayan aikin Aerospace) da masana'antar sufuri inda rage nauyi yake da mahimmanci.
Don haka, bakin karfe ya fi karfi gaba ɗaya, amma ƙwayoyin aluminum lokacin da wutar lantarki mara nauyi.
3. Corrous jure
Dukkan metals suna tsayayya da lalata, amma hanyoyinsu sun sha bamban.
Bakin karfe:
Chromium a cikin bakin karfe yana amsawa tare da oxygen don samar da kariya mai kariya chromium Oxide Layer. Wannan Layer na warkarwa kai yana hana tsatsa, koda lokacin da aka kewaye shi. Grades kamar 316 bakin karfe ƙara molybdenum don karin jure da gishiri da ruwan gishiri.
Goron ruwa:
Allumin halitta ya samo asali ne mai bakin ciki,, yana kare shi daga hadawan abu daban-daban. Koyaya, yana da yiwuwar lalata galvanic lokacin da aka haɗu da karancin ƙarfe a cikin mahalli m. Anodizing ko mayafin na iya haɓaka juriya.
Don haka, bakin karfe yana ba da juriya da lalata juriya, yayin da aluminum yana buƙatar maganin kariya a cikin mawuyacin yanayi.
4. Weight: Aluminum ya yi nasara don aikace-aikacen Haske
Yankunan aluminum shine kusan 2.7 g / cm³, ƙasa da na uku na bakin karfe 8 g / cm³,wanda yake sosai mai nauyi.
·Jirgin sama da sassan motoci
·Mai amfani da lantarki (misali, kwamfyutoci)
·Kayan masu amfani kamar kekuna da kayan zango
Bakin Karfe na HEFT shine fa'ida a aikace-aikacen da ke buƙatar kwanciyar hankali, kamar injunan masana'antu ko tallafin kayan gini.

Yin aiki da hasken rana:
Aluminum yana da zafi fiye da bakin karfe, yana yin daidai da ɗakunan zafi, cookware, da tsarin Hvac.
Aikin lantarki:
Ana amfani da aluminium da yadu sosai a cikin layin wutar lantarki da wayoyi na lantarki saboda babban halin ta (kashi 61% na jan ƙarfe). Bakin karfe shine talakawa mai ɗaukar hankali kuma ba a taɓa amfani da shi a aikace-aikacen lantarki ba.
6. Kwatancen farashi
Alumum:
Gabaɗaya mai rahusa fiye da bakin karfe, tare da farashin yana canzawa bisa farashin kuzari (samar da aluminium yana da ƙarfi-ƙarfi). Kamar yadda na 2023, farashi na aluminum ~ $ 2,500 a kan awo.
Bakin karfe:
Mafi tsada saboda abubuwan da suka yi kama da chromium da nickel. Sauki 304 Bakin Karfe Matsakaicin ~ $ 3,000 a kan awo ton.
Tukwici:Don ayyukan kasafin kudi inda al'amuran masu nauyi, za su zaɓi aluminium. Don tsawon rai a cikin yanayin m, bakin bakin karfe na iya gaskata mafi tsada.
7. Mabani da ƙira
Alumum:
Softer da sauƙi a yanka, lanƙwasa, ko kuma ta ƙonewa. Mafi dacewa ga hadaddun siffofi da sauri. Koyaya, zai iya gums kayan aikin saboda melting nuni.
Bakin karfe:
Da wuya a injin, yana buƙatar kayan aiki na musamman da saurin gudu. Koyaya, yana riƙe da siffofi daidai da ƙarewa da kyau, dacewa da na'urorin likita ko bayanan gine-gine.
Don waldi, bakin karfe yana buƙatar kare iska ta ƙasa (TIG / Mig), yayin da aluminum ya nemi gogewa don guje wa warping.
8. Aikace-aikace na kowa
Aluminum yayi amfani da:
·Aerospace (Jirgin Sama)
·Wagagging (gwangwani, tsare)
·Gini (Falle na taga, rufin)
·Sufuri (motoci, jiragen ruwa)
Bakin karfe yayi amfani da:
·Kayan aikin likita
·Kayan kayan kitchen (nutsewa, cutery)
·Sunadarai masu sarrafawa
·Marine Hardware (Remun jirgin kwale)
9. Dore da Cikewa da Sake Kariya
Dukkanin metals na 100% sake dawowa:
·Aluminum recycling ya ceci 95% na makamashi da ake buƙata don firam na farko.
· Bakin karfe za a iya sake yin amfani da shi ba tare da asara mai inganci ba, rage nauyin ma'adinai.
Kammalawa: Wanne ya kamata ku zaɓi?
Zabi aluminum idan:
·Kuna buƙatar sauƙi, abu mai tsada mai tsada.
·Aikin da ke kan themal / wutan lantarki yana da mahimmanci.
·Wannan aikin bai ƙunshi matsanancin damuwa ba ko kuma mahalli marasa galihu.
Zabi bakin karfe idan:
·Ƙarfi da lalata juriya sune manyan abubuwan da suka fi muhimmanci.
·Aikace-aikacen ya shafi yanayin zafi ko matsananciyar ƙira.
·Kokarin da aka kira (misali, an goge shi kare) al'amura.
