Zigawo zamkuwa

Kufotokozera Kwachidule:

Brass alloy ndi aloyi yamkuwa ndi zinki, molingana ndi zomwe zimatha kusiyanasiyana kuti zitheke pamakina, magetsi, ndi mankhwala.Ndilo cholowa m'malo: maatomu a zigawo ziwirizi amatha kulowa m'malo mwamtundu womwewo wa kristalo.

Chiyambi cha zigawo za Brass alloy

Mkuwa ndi wofanana ndi mkuwa, aloyi wina munali mkuwa amene amagwiritsa malata m'malo zinki. Onse mkuwa ndi mkuwa angaphatikizepo yaing'ono ya zosiyanasiyana zinthu zina kuphatikizapo arsenic, kutsogolera, phosphorous, zotayidwa, manganese, ndi pakachitsulo.M'mbiri, kusiyana pakati pa ma aloyi awiriwa sikunasinthe komanso kumveka bwino, ndipo machitidwe amakono osungiramo zinthu zakale ndi zofukulidwa m'mabwinja amapewa kwambiri mawu onse azinthu zakale zomwe zimagwirizana ndi "copper alloy".

Mkuwa wakhala chinthu chodziwika bwino chokongoletsera chifukwa cha maonekedwe ake owala, ngati golide;amagwiritsidwa ntchito pokoka ma drawer ndi zitseko.Amagwiritsidwanso ntchito kwambiri popanga ziwiya chifukwa cha zinthu monga kukhala ndi malo osungunuka otsika, okwera kwambiri (zonse ndi zida zamanja komanso makina amakono otembenuza ndi mphero), kulimba, ndi magetsi ndi matenthedwe conductivity.

Kugwiritsa ntchito zigawo za Brass alloy

Brass alloy imagwiritsidwabe ntchito nthawi zambiri pamapulogalamu omwe kukana kwa dzimbiri ndi kukangana kochepa kumafunikira, monga maloko, mahinji, magiya, mayendedwe, ma casing a zida, zipper, mapaipi, zolumikizira payipi, ma valve, ndi mapulagi amagetsi ndi soketi.Amagwiritsidwa ntchito kwambiri pazida zoimbira monga nyanga ndi mabelu, komanso amagwiritsidwa ntchito m'malo mwa mkuwa popanga zodzikongoletsera, zodzikongoletsera, ndi zodzikongoletsera zina.Kapangidwe ka mkuwa, kaŵirikaŵiri 66% yamkuwa ndi 34% zinki, kumapangitsa kukhala cholowa m'malo mwa zodzikongoletsera zamkuwa, chifukwa zimawonetsa kukana kwambiri kwa dzimbiri.Mkuwa umagwiritsidwa ntchito nthawi zambiri m'malo omwe ndikofunikira kuti zisawopsedwe, monga zopangira ndi zida zomwe zimagwiritsidwa ntchito pafupi ndi zinthu zoyaka kapena kuphulika.

Mitundu yonse ya zigawo za Brass alloy

Kalasi	Kuchuluka kwa kulemera (%)		Zolemba
Kalasi	Mkuwa	Zinc	Zolemba
Alpha bras	> 65	<35	Ma alpha brasses ndi osinthika, amatha kugwiritsidwa ntchito mozizira, ndipo amagwiritsidwa ntchito kukanikiza, kufota, kapena ntchito zina zofananira.Zili ndi gawo limodzi lokha, lokhala ndi mawonekedwe amtundu wa cubic crystal.Chifukwa cha kuchuluka kwawo kwa mkuwa, mikuwa iyi imakhala ndi golide wambiri kuposa ena.The alpha gawo ndi m'malo olimba njira ya zinki mu mkuwa.Ili pafupi kwambiri ndi mkuwa, yolimba, yamphamvu, komanso yovuta kuyipanga makina.Mapangidwe abwino kwambiri ndi 32% ya zinc.Mikuwa yofiyira yosachita dzimbiri, yokhala ndi 15% ya zinki kapena kuchepera, ili pano.
Alpha-beta brasses	55–65	35–45	Amatchedwansoduplex mkuwa, izi ndizoyenera kugwira ntchito yotentha.Amakhala ndi magawo onse a α ndi β;gawo la β'-gawo limalamulidwa ndi thupi la cubic, yokhala ndi maatomu a zinki pakati pa ma cubes, ndipo ndi yolimba komanso yamphamvu kuposa α.Ma alpha-beta brasses nthawi zambiri amagwiritsidwa ntchito kutentha.Kuchuluka kwa zinc kumatanthauza kuti mikuwa iyi ndi yowala kuposa ma alpha brasses.Pa 45% ya zinki alloy ali ndi mphamvu kwambiri.
Mitundu ya beta	50-55	45-50	Ma beta brasses amatha kugwiritsidwa ntchito kutentha, ndipo ndizovuta, zamphamvu, komanso zoyenera kuponyedwa.Mkuwa wambiri wa zinc umatanthauza kuti izi ndi zina mwazitsulo zowala kwambiri komanso zagolide.
Mitundu ya gamma	33–39	61–67	Palinso Ag-Zn ndi Au-Zn gamma brasses, Ag 30–50%, Au 41%.Gamma gamma ndi cubic-lattice intermetallic compound, Cu.₅Zn₈.
Mkuwa woyera	<50	> 50	Izi ndizovuta kwambiri kuti zigwiritsidwe ntchito.Mawuwa angatanthauzenso mitundu ina ya ma aloyi a siliva a faifi tambala komanso ma aloyi a Cu-Zn-Sn okhala ndi kuchuluka kwakukulu (nthawi zambiri 40%+) ya malata ndi/kapena zinki, komanso ma aloyi ambiri opangira zinki okhala ndi zowonjezera zamkuwa.Izi zilibe mtundu wachikasu konse, ndipo m'malo mwake zimakhala ndi mawonekedwe asiliva.
