High-silicon aluminum gami ne wani binary gami hada silicon da aluminum, kuma shi ne karfe-tushen thermal kayan abu. Babban kayan siliki na aluminium na iya kula da kyawawan kaddarorin silicon da aluminium, baya gurɓata muhalli, kuma ba shi da lahani ga jikin ɗan adam. Yawan allurar aluminium mai ƙarfi yana tsakanin 2.4 ~ 2.7 g/cm³, kuma daidaiton haɓaka zafi (CTE) yana tsakanin 7-20ppm/℃. Ƙara abun ciki na siliki na iya rage ƙima da ƙima mai yawa na kayan gami. A lokaci guda, babban silicon aluminium shima yana da kyawawan halayen zafi, madaidaiciyar taurin kai da taurin kai, kyakkyawan aikin plating tare da zinare, azurfa, jan ƙarfe, da nickel, weldable tare da substrate, da sauƙi madaidaiciyar injin. Yana da kayan tattara kayan lantarki tare da fa'idodin aikace -aikace masu yawa.

Hanyoyin ƙera manyan kayan siliki na aluminium gami da abubuwan haɗaɗɗun abubuwa galibi sun haɗa da masu zuwa: 1) narkewa da simintin gyare-gyare; 2) hanyar kutsawa; 3) ƙarfe na ƙarfe; 4) hanyar matsi mai zafi; 5) Hanyar sanyaya/fesawa da sauri.

Tsarin Samarwa

1) Hanyar narkewa da siminti

Kayan aiki don narkewa da hanyar simintin gyare-gyare yana da sauƙi, farashi mai sauƙi, kuma yana iya aiwatar da manyan masana'antun masana'antu, kuma ita ce mafi girman hanyar shiri don kayan gami.

2) Hanyar yin ciki

Hanyar sakawa ta kunshi hanyoyi biyu: hanyar kutsawa matsin lamba da hanyar kutse mara matuki. Hanyar shigar da matsin lamba yana amfani da matsin lamba na inji ko matsi na gas don sanya gindin ƙarfe ya narke cikin ramin ƙarfafawa.

3) Karfewar ƙarfe

Metallurgy na ƙarfe shine ya tarwatsa wani rabo na aluminium foda, silicon foda da mai ɗaure iri ɗaya, haɗe da sifar foda ta latsa bushewa, allura da sauran hanyoyin, kuma a ƙarshe ya yi rauni a cikin yanayin kariya don samar da abu mai yawa.

4) Hanyar matse injin zafi

Hanyar matsewar zafi mai zafi tana nufin tsarin nutsewa inda ake aiwatar da matsi da matsin lamba a lokaci guda. Amfaninta shine: ①Foda yana da sauƙi don kwararar filastik da yawa; Can zafin zafin da ke ɓarna da lokacin ƙanƙancewa gajeru ne; DensityAn yi yawa. Tsarin gabaɗaya shine: a ƙarƙashin yanayin ɓarna, ana sanya foda a cikin rami mai ƙyalli, ana ɗora foda yayin da ake matsa lamba, kuma an samar da ƙaramin abu da kayan aiki bayan ɗan gajeren lokacin matsa lamba.

5) Saurin sanyaya/zubar da ruwa

Fasahar sanyaya sauri/fesa fasahar fasaha ce mai ƙarfi mai ƙarfi. Yana da fa'idodi masu zuwa: 1) babu wariyar launin fata; 2) madaidaiciya da daidaiton madaidaicin kristal microstructure; 3) kyakkyawan lokacin hazo na farko; 4) ƙarancin iskar oxygen; 5) inganta aikin sarrafa zafi.

Rarraba

(1) Hypoeutectic silicon aluminum gami ya ƙunshi silicon 9% -12%.

(2) Eutectic silicon aluminum gami ya ƙunshi 11% zuwa 13% silicon.

(3) Abun silicon na ƙarfe na aluminium na sama yana sama da 12%, galibi a cikin kewayon 15%zuwa 20%.

(4) Wadanda ke da abun siliki na 22% ko sama da haka ana kiransu allurar aluminium mai girma, wanda 25% -70% sune manyan, kuma mafi girman abun cikin silicon a duniya zai iya kaiwa 80%.

Aikace -aikace

1) Babban ƙarfin haɗaɗɗen fakiti na kewaye: ƙaramin siliki na aluminium yana ba da ingantaccen watsawar zafi;

2) Mai ɗaukar kaya: Ana iya amfani da shi azaman matattara mai zafi na gida don yin abubuwan da aka tsara sosai;

3) Tantancewar firam: babban siliki na aluminium yana ba da ƙarancin ƙarancin faɗaɗawar zafi, babban ƙarfi da aiki;

4) Ruwan zafi: Babban siliki na aluminium yana ba da ingantaccen watsawar zafi da tallafin tsari.

5) Sassan atomatik: Babban kayan siliki na aluminium (abun ciki na siliki 20%-35%) yana da kyawawan kaddarorin tribological, kuma ana iya amfani dashi azaman kayan haɓaka mai ƙarfi mai sauƙin nauyi don amfani a cikin kayan aikin sufuri daban-daban, injunan wutar lantarki daban-daban, da injin kayan aiki. , An yi amfani da kayan sakawa da kayan aiki na musamman.

Alloy aluminum gami yana da jerin fa'idodi kamar ƙaramin takamaiman nauyi, nauyi mai nauyi, kyakkyawan yanayin ɗorewar zafi, ƙarancin ƙarancin zafi mai ƙarfi, kwanciyar hankali, ingantaccen juriya, da juriya mai kyau, kuma ana amfani dashi sosai azaman silinda, pistons, da rotors na injunan mota. , Faifan birki da sauran kayan.
