Umucu wethusifuthiumugqa wethusi onomthofukukhona imichilo emibili ye-alloy yethusi evamile, umehluko omkhulu usekubunjweni, ekusebenzeni nasekusetshenzisweni.
Ⅰ. Ukwakheka
1. I-Brass ikakhulukazi yenziwe ngethusi (Cu) ne-zinc (Zn), enesilinganiso esivamile se-60-90% yethusi kanye ne-10-40% ye-zinc. Amabanga ajwayelekile afaka i-H62, H68, njll.
2. Ithusi eliholayo i-alloy yethusi-zinc ene-lead (Pb) eyengeziwe, futhi okuqukethwe okuholayo kuvame ukuba ngu-1-3%. Ngaphezu kokuhola, kungase futhi kuqukathe inani elincane lezinye izakhi, njengensimbi, i-nickel noma i-tin, njll. Ukwengezwa kwalezi zakhi kungathuthukisa kakhulu ukusebenza kwe-alloy. Amabanga ajwayelekile afaka i-HPb59-1, HPb63-3, njll.
II. Izici zokusebenza
1. Izakhiwo zemishini
(1)Ithusi: Ngokushintshwa kokuqukethwe kwe-zinc, izakhiwo zemishini zihlukile. Uma okuqukethwe kwe-zinc kungadluli ku-32%, amandla kanye ne-plasticity yanda ngokukhula kokuqukethwe kwe-zinc; ngemuva kokuthi okuqukethwe kwe-zinc kudlule i-32%, i-plasticity yehla kakhulu, futhi amandla afinyelela inani eliphakeme eduze nokuqukethwe kwe-zinc kwe-45%.
(2)Ithusi eliholayo: Inamandla amahle, futhi ngenxa yokuba khona komthofu, ukumelana kwayo nokugqoka kungcono kunethusi elivamile.
2. Ukucubungula ukusebenza
(1)Ithusi: Inepulasitiki enhle futhi ingakwazi ukumelana nokushisa nokubanda, kodwa ijwayele ukuba nokushisa okuphakathi nendawo ngesikhathi sokucubungula okushisayo njengokubumba, ngokuvamile phakathi kuka-200-700 ℃
(2)Ithusi eliholayo: Inamandla amahle, futhi ngenxa yokuba khona komthofu, ukumelana kwayo nokugqoka kungcono kunethusi elivamile. Isimo esikhululekile somthofu siyenza idlale indima yokunciphisa ukungqubuzana phakathi nenqubo yokungqubuzana, okunganciphisa ngempumelelo ukuguga.
3. Izakhiwo zomzimba namakhemikhali
(1) Ithusi: Ine-conductivity kagesi enhle, i-thermal conductivity kanye nokumelana nokugqwala. Igqwala kancane kakhulu emkhathini futhi ayisheshi kakhulu emanzini ahlanzekile, kodwa igqwala ngokushesha emanzini olwandle. Emanzini aqukethe amagesi athile noma ezindaweni ezithile ze-acid-base, izinga lokugqwala lizoshintsha.
(2) Ithusi eliholayo: I-conductivity yayo kagesi neyokushisa ingaphansi kancane kunethusi, kodwa ukumelana kwayo nokugqwala kufana nokokwethusi. Kwezinye izindawo ezithile, ngenxa yomphumela womthofu, ukumelana nokugqwala kwawo kungase kugqame kakhulu.
3. Izicelo
(1)Imichilo yethusiziguquguquka kakhulu futhi zilungele izikhathi ezahlukahlukene, ikakhulukazi lezo ezidinga ukwakheka okuhle kanye nekhwalithi ephezulu.
1) Imboni ye-elekthronikhi nekagesi: izixhumi, amatheminali, amakhava okuvikela, njll.
2) Umhlobiso wezakhiwo: izibambo zeminyango, imichilo yokuhlobisa, njll.
3) Ukukhiqizwa kwemishini: ama-gaskets, iziphethu, amasinki okushisa, njll.
4) Izingxenyekazi zekhompuyutha zansuku zonke: iziphuphu, izinkinobho, njll.
(2)Umucu wethusi oholayoinokusebenza okuhle kakhulu kokusika futhi ifanele ukwenziwa ngokunemba kwemishini, kodwa kufanele kuqashelwe izindaba zemvelo nempilo yomthofu. Ezinhlelweni zamanzi okuphuza kanye nezindawo ezinezidingo eziphakeme zokuvikela imvelo, kunconywa ukusebenzisa umugqa wethusi ongenamthofu.
1) Izingxenye zokunemba: izingxenye zewashi, amagiya, amavalvu, njll.
2) Imishini kagesi: izixhumi ezinemba okuphezulu, amatheminali, njll.
3) Imboni yezimoto: izingxenye zesistimu kaphethiloli, izindlu zezinzwa, njll.
