1. Abun Haɗa: Me Aka Yi Su?

Bambanci na asali tsakanin aluminum da bakin karfe yana cikin abun da ke ciki.

Aluminumkarfe ne mara nauyi, farar azurfa da aka samu a cikin ɓawon ƙasa. Tsaftataccen aluminum yana da taushi, don haka galibi ana haɗa shi da abubuwa kamar jan ƙarfe, magnesium, ko silicon don haɓaka ƙarfi. Alal misali, 6061 aluminum gami da aka yi amfani da ko'ina ya ƙunshi magnesium da silicon.

Bakin Karfewani ƙarfe ne na tushen ƙarfe wanda ya ƙunshi aƙalla 10.5% chromium, wanda ke haifar da Layer oxide mai wucewa don tsayayya da lalata.. Maki guda kamar 304 bakin karfe kuma sun haɗa da nickel da carbon.

2. Karfi da Dorewa

Bukatun ƙarfi sun bambanta ta aikace-aikace, don haka bari mu kwatanta halayen injin su.

Bakin Karfe:

Bakin karfe yana da ƙarfi sosai fiye da aluminium, musamman a cikin mahalli mai tsananin damuwa. Misali, sa 304 bakin karfe yana da karfin juriya na ~505 MPa, idan aka kwatanta da 6061 aluminum ~ 310 MPa.

Aluminum:

Duk da yake ƙasa da ƙarfi ta ƙara, aluminum yana da mafi kyawun ƙarfin-zuwa nauyi rabo. Wannan ya sa ya zama cikakke ga abubuwan haɗin sararin samaniya (kamar firam ɗin jirgin sama) da masana'antar sufuri inda rage nauyi ke da mahimmanci.

Don haka, bakin karfe ya fi ƙarfi gabaɗaya, amma aluminum ya fi ƙarfin lokacin da ƙarfin nauyi ya fi dacewa.

3. Juriya na Lalata

Dukansu karafa suna tsayayya da lalata, amma hanyoyin su sun bambanta.

Bakin Karfe:

Chromium a cikin bakin karfe yana amsawa da iskar oxygen don samar da Layer chromium oxide mai kariya. Wannan Layer na warkar da kai yana hana tsatsa, ko da lokacin da aka taso. Maki kamar 316 bakin karfe suna ƙara molybdenum don ƙarin juriya ga ruwan gishiri da sinadarai.

Aluminum:

Aluminum a dabi'a yana samar da sirin oxide Layer, yana kare shi daga iskar oxygen. Koyaya, yana da saurin lalata galvanic idan an haɗa shi da nau'ikan ƙarfe iri ɗaya a cikin mahalli masu ɗanɗano. Anodizing ko sutura na iya haɓaka juriya.

Don haka, bakin karfe yana ba da ƙarin juriya mai ƙarfi, yayin da aluminium yana buƙatar jiyya na kariya a cikin mawuyacin yanayi.

4. Nauyi: Aluminum Wins don Aikace-aikace masu nauyi

Girman Aluminum kusan 2.7 g/cm³, ƙasa da kashi uku na bakin karfe 8 g/cm³,wanda yake da nauyi sosai.

·Jirgin sama da na motoci

·Kayan lantarki masu ɗaukar nauyi (misali, kwamfyutoci)

·Kayayyakin mabukaci kamar kekuna da kayan zango

Heft na bakin karfe yana da fa'ida a cikin aikace-aikacen da ke buƙatar kwanciyar hankali, kamar injinan masana'antu ko tallafin gine-gine.

5. Thermal da Wutar Lantarki

Ƙarfafa Ƙarfafawa:

Aluminum yana gudanar da zafi 3x mafi kyau fiye da bakin karfe, yana mai da shi manufa don dumama zafi, kayan dafa abinci, da tsarin HVAC.

Wutar Lantarki:

Aluminum ana amfani da shi sosai a cikin layukan wutar lantarki da na'urorin lantarki saboda ƙarfin ƙarfinsa (61% na jan ƙarfe). Bakin karfe mara kyaun madugu ne kuma ba kasafai ake amfani dashi a aikace-aikacen lantarki ba.

6. Kwatancen farashi

Aluminum:

Gabaɗaya mai rahusa fiye da bakin karfe, tare da canje-canjen farashin dangane da farashin makamashi (samar da aluminum yana da ƙarfi). Tun daga shekarar 2023, farashin aluminium ~ $2,500 a kowace tan metric.

Bakin Karfe:

Mafi tsada saboda abubuwan haɗakarwa kamar chromium da nickel. Matsakaicin matsakaicin bakin karfe 304 ~ $3,000 a kowace ton metric.

Tukwici:Don ayyukan da suka dace da kasafin kuɗi inda nauyin nauyi, zaɓi aluminum. Don dadewa a cikin mahalli masu tsauri, bakin karfe na iya tabbatar da mafi girman farashi.

7. Injiniya da Kerawa

Aluminum:

Mai laushi da sauƙi don yanke, lanƙwasa, ko fiɗa. Mafi dacewa don hadaddun siffofi da saurin samfur. Duk da haka, yana iya ƙulla kayan aiki saboda ƙarancin narkewa.

Bakin Karfe:

Ƙarfin inji, yana buƙatar kayan aiki na musamman da saurin gudu. Koyaya, yana riƙe da madaidaicin siffofi kuma ya ƙare da kyau, wanda ya dace da na'urorin likitanci ko cikakkun bayanai na gine-gine.

Don waldawa, bakin karfe yana buƙatar garkuwar iskar gas (TIG/MIG), yayin da aluminium yana buƙatar ƙwararrun kulawa don gujewa warping.
