Menene Bambanci Tsakanin Aluminum da Bakin Karfe?

Lokacin zabar kayan gini, masana'antu, ko ayyukan DIY, aluminum da bakin karfe guda biyu ne daga cikin karafa mafi shahara. Amma me ya bambanta su? Ko kai injiniya ne, mai sha'awar aiki, ko kuma kawai kana son sani, fahimtar bambance-bambancen su na iya taimaka maka ka yanke shawara mai kyau. A cikin wannan shafin yanar gizo, za mu raba kadarorinsu, aikace-aikacensu, farashinsu, da ƙari - waɗanda kwararru suka tallafa musu - don taimaka maka ka zaɓi kayan da ya dace da buƙatunka.

1. Tsarin: Daga Me Aka Yi Su?

Babban bambanci tsakanin aluminum da bakin karfe yana cikin abubuwan da suka ƙunsa.

Aluminumƙarfe ne mai sauƙi, mai launin fari da azurfa wanda ake samu a cikin ɓawon duniya. Tsarkakken aluminum yana da laushi, don haka sau da yawa ana haɗa shi da abubuwa kamar jan ƙarfe, magnesium, ko silicon don ƙara ƙarfi. Misali, ƙarfen aluminum 6061 da ake amfani da shi sosai ya ƙunshi magnesium da silicon.

Bakin Karfewani ƙarfe ne mai ƙarfe wanda ke ɗauke da aƙalla chromium 10.5%, wanda ke ƙirƙirar layin oxide mai aiki don tsayayya da tsatsaNau'ikan da aka saba amfani da su kamar bakin karfe 304 suma sun haɗa da nickel da carbon.

2. Ƙarfi da Dorewa

Bukatun ƙarfi sun bambanta dangane da amfani, don haka bari mu kwatanta halayen injinan su.

Bakin Karfe:

Bakin ƙarfe ya fi aluminum ƙarfi sosai, musamman a yanayin da ke da matuƙar damuwa. Misali, ƙarfe mai nauyin 304 mai nauyin 304 yana da ƙarfin tauri na ~505 MPa, idan aka kwatanta da ƙarfe mai nauyin 6061 mai nauyin ~310 MPa.

Aluminum:

Duk da cewa ƙarfin aluminum bai yi yawa ba, amma yana da mafi kyawun rabon ƙarfi da nauyi. Wannan ya sa ya zama cikakke ga sassan sararin samaniya (kamar firam ɗin jirgin sama) da masana'antar sufuri inda rage nauyi yake da mahimmanci.

Don haka, bakin karfe ya fi ƙarfi gabaɗaya, amma aluminum ya fi kyau idan ƙarfin nauyi ya zama dole.

3. Juriyar Tsatsa

Dukansu karafa suna tsayayya da tsatsa, amma hanyoyinsu sun bambanta.

Bakin Karfe:

Chromium da ke cikin bakin karfe yana amsawa da iskar oxygen don samar da wani Layer na chromium oxide mai kariya. Wannan Layer mai warkar da kansa yana hana tsatsa, koda lokacin da aka karce. Daraja kamar 316 bakin karfe yana ƙara molybdenum don ƙarin juriya ga ruwan gishiri da sinadarai.

Aluminum:

Aluminum ta halitta tana samar da siririn oxide, wanda ke kare ta daga iskar shaka. Duk da haka, tana iya kamuwa da tsatsa ta galvanic idan aka haɗa ta da ƙarfe daban-daban a cikin yanayi mai danshi. Ana yin anodizing ko shafa fata na iya ƙara juriyarsa.

Don haka, bakin karfe yana ba da ƙarin juriya ga tsatsa, yayin da aluminum ke buƙatar maganin kariya a cikin mawuyacin yanayi.

4. Nauyi: Nasarar Aluminum don Aikace-aikacen Sauƙi

Yawan aluminum yana da kusan 2.7 g/cm³, ƙasa da kashi ɗaya bisa uku na 8 g/cm³ na bakin karfe.wanda yake da nauyi sosai.

·Sassan Jiragen Sama da na Motoci

·Kayan lantarki masu ɗaukuwa (misali, kwamfyutocin tafi-da-gidanka)

·Kayayyakin masu amfani kamar kekuna da kayan sansani

Ƙarfin ƙarfe na bakin ƙarfe fa'ida ne a aikace-aikacen da ke buƙatar kwanciyar hankali, kamar injinan masana'antu ko tallafin gine-gine.

5. Tsarin Zafi da Wutar Lantarki

Tsarin kwararar zafi:

Aluminum yana sarrafa zafi sau uku fiye da bakin karfe, wanda hakan ya sa ya dace da wurin wanke zafi, kayan girki, da tsarin HVAC.

Lantarki Mai Aiki:

Ana amfani da aluminum sosai a layukan wutar lantarki da wayoyin lantarki saboda yawan wutar lantarki (kashi 61% na jan ƙarfe). Bakin ƙarfe ba shi da kyau wajen sarrafa wutar lantarki kuma ba a cika amfani da shi ba a fannin amfani da wutar lantarki.

6. Kwatanta Farashi

Aluminum:

Gabaɗaya ya fi bakin ƙarfe araha, tare da farashin yana canzawa dangane da farashin makamashi (haɓaka aluminum yana buƙatar makamashi). Kamar yadda yake a shekarar 2023, farashin aluminum ya kai ~$2,500 a kowace tan na metric.

Bakin Karfe:

Ya fi tsada saboda abubuwan da ke haɗa ƙarfe kamar chromium da nickel. Matsakaicin ƙarfe mai nauyin 304 yana da matsakaicin ~$3,000 a kowace tan na metric.

Shawara:Don ayyukan da suka dace da kasafin kuɗi inda nauyi ke da mahimmanci, zaɓi aluminum. Domin tsawon rai a cikin mawuyacin yanayi, bakin ƙarfe na iya ba da hujjar hauhawar farashi.

7. Tsarin aiki da ƙera

Aluminum:

Ya fi laushi kuma ya fi sauƙi a yanka, lanƙwasa, ko fitar da shi. Ya dace da siffofi masu rikitarwa da kuma saurin yin samfuri. Duk da haka, yana iya goge kayan aiki saboda ƙarancin narkewar sa.

Bakin Karfe:

Yana da wahalar na'ura, yana buƙatar kayan aiki na musamman da kuma saurin gudu. Duk da haka, yana da siffofi da ƙarewa daidai, wanda ya dace da na'urorin likita ko cikakkun bayanai na gine-gine.

Don walda, bakin karfe yana buƙatar kariyar iskar gas mara aiki (TIG/MIG), yayin da aluminum ke buƙatar ƙwarewa wajen sarrafawa don guje wa karkacewa.
