Te parahi mata
Ko te mata he tino kore e rewa ki te parahi, ka tohatohahia ki nga rohe o te witi i roto i te ahua o nga matūriki kore utu.E ai ki tana whakahaere, e rua nga momo o te parahi mata: α me (α+β).Na te kino o te mata, he iti rawa te wera o te wera o te parahi o te alpha-lead, no reira ka taea te whakamatao noa, te wera wera ranei.(α+β) He pai te kirihou o te parahi mata i te pāmahana teitei, ka taea te hanga.
Te parahi tine
Ko te taapiri i te tine ki te parahi ka taea te whakapai ake i te wera o te koranu, ina koa te kaha ki te aukati i te waikura o te moana, na reira ka kiia te parahi tine ko "parahi moana".
Ka tareka te tine ki roto i te wairewa totoka e hangai ana ki te parahi me te purei i te painga whakakaha wairewa totoka.Engari i te pikinga o te ihirangi tine, ka puta te wahanga r-waahanga (CuZnSn compound) i roto i te koranu, kaore e pai ki te rerekee o te kirihou o te koranu, no reira ko te ihirangi tine o te parahi tine kei te nuinga o te 0.5% ki te 1.5%.
He HSn70-1, HSn62-1, HSn60-1 me etahi atu nga parahi tine e whakamahia ana.Ko te mea o mua he koranu alpha, he kirihou teitei, ka taea te tukatuka ma te pehanga makariri me te wera.Ko nga koranu o nga reanga e rua o muri nei he (α+β) te hanganga e rua-waahanga, he iti noa te waahi-r i te nuinga o te waa, kaore i te teitei te kirihou i te pāmahana rūma, ka taea anake te whakarereke i te wera. āhua.
Parahi Konupora
He nui ake te whakarewatanga o te konupora ki te parahi totoka.Ko te taapiri i te 1% ki te 4% o te konupora ki te parahi ka taea te whakanui ake i te kaha me te aukati i te waikura o te koranu me te kore e whakaiti i tona kirihou.
Ko te parahi konupora he (α+β) te hanganga, me te HMn58-2 e whakamahia nuitia ana, a he tino pai tana mahi tukatuka pehanga i raro i te makariri me te wera.
parahi rino
I roto i te parahi rino, ka pupuhi te rino me nga matūriki wahanga rino, e mahi ana hei karihi karaihe hei whakamahine i nga kakano karaihe me te aukati i te tipu o nga kakano rerystallized, na reira ka whakapai ake i nga ahuatanga miihini me nga mahi o te koranu.Ko te ihirangi rino i roto i te parahi rino i te nuinga o te waa kei raro iho i te 1.5%, ko tona hanganga (α + β), he nui te kaha me te pakari, he pai te kirihou i nga wera nui, a ka taea te whakarereke i nga ahuatanga makariri.Ko Hfe59-1-1 te kōeke e whakamahia nuitia ana.
parahi nikeli
Ka taea e te Nickel me te parahi te hanga i te otinga totoka tonu, e tino whakanuia ana te rohe-waa-a-a.Ko te taapiri o te nickel ki te parahi ka tino pai ake te aukati i te waikura o te parahi i roto i te hau me te wai moana.Ka taea hoki e Nickel te whakanui ake i te whakamahana whakamaarama o te parahi me te whakatairanga i te hanganga o nga karepe pai ake.
Ko te HNi65-5 nickel brass he hanganga α kotahi-waahanga, he pai te kirihou i te pāmahana rūma, ka taea hoki te whakarereke i raro i nga tikanga wera.Heoi, me tino whakahaere nga ihirangi o te mata poke, kei tino kino te mahi wera o te koranu.
He 750～830 ℃ te pāmahana tukatuka waiariki;ko te 520~650 ℃ te pāmahana whakaeneene;Ko te iti o te pāmahana whakahiato hei whakakore i te ahotea o roto ko te 260 ~ 270 ℃.
Ko te parahi tiaki taiao C26000 C2600 he pai te kirihou, te kaha teitei, te pai o te miihini, te whakapiri, te pai o te waikura, te whakawhiti wera, te paipa pepa, te miihini, nga waahanga hiko.
Whakatakotoranga (mm): Whakaritenga: te matotoru: 0.01-2.0mm, te whanui: 2-600mm;
