Monga dzina likunenera,mkuwa wapamadzindi aloyi yamkuwa yoyenera pazithunzi zam'madzi. Zigawo zake zazikulu ndi mkuwa (Cu), nthaka (Zn) ndi malata (Sn). Aloyi imeneyi imatchedwanso malata mkuwa. Kuphatikizika kwa malata kumatha kuletsa bwino kufota kwa mkuwa ndikuwongolera kukana kwa dzimbiri.
M'madzi am'madzi, filimu yoteteza yopyapyala komanso yowundana idzapanga pamwamba pa aloyi yamkuwa, yomwe imapangidwa makamaka ndi mkuwa ndi tini oxides ndi mchere wovuta. Chigawo chotetezachi chingathandize kuti madzi a m’nyanja asachite dzimbiri m’kati mwa alloy ndi kuchepetsa dzimbiri. Poyerekeza ndi mkuwa wamba, kuchuluka kwa dzimbiri kwa mkuwa wapamadzi kumatha kuchepetsedwa kangapo.
Mitundu yambiri yamkuwa yamkuwa imaphatikizapoC44300(HSn70-1/T45000), yomwe ili ndi izi:
Mkuwa (Cu): 69.0% - 71.0%
Zinc (Zn): Kusamalitsa
Malata (Sn): 0.8% - 1.3%
Arsenic (As): 0.03% - 0.06%
Zinthu zina zophatikizira: ≤0.3%
Arsenic imatha kulepheretsa dzincification corrosion ndikupititsa patsogolo kukana kwa dzimbiri kwa alloy.C44300 ili ndi zida zabwino zamakina ndipo imagwiritsidwa ntchito popanga zosinthira kutentha ndi ma condus omwe amakumana ndi zakumwa zowononga. Amagwiritsidwa ntchito kwambiri m'mafakitale opangira magetsi otenthetsera kumtunda kupanga machubu a condenser amphamvu kwambiri, osachita dzimbiri. Kafukufuku waposachedwa wasonyeza kuti kuwonjezera kuchuluka kwa boron, faifi tambala ndi zinthu zina ku C44300 kumatha kupititsa patsogolo kukana kwa dzimbiri. C44300 ili ndi chizolowezi chogogomezera kung'ambika kwa dzimbiri, ndipo mapaipi opangidwa ndi kuzizira amayenera kuthandizidwa ndi kupsinjika ndi kutentha pang'ono. C44300 imakonda kusweka pa kukanikiza kotentha, ndipo zomwe zili zonyansa ziyenera kuyendetsedwa mosamalitsa.
C46400(HSn62-1 / T46300) ndi mkuwa wapamadzi wokhala ndi mkuwa wocheperako. Zigawo zake zazikulu ndi izi:
Kuchuluka: 61-63%
Zn: 35.4-38.3%
Sn: 0.7-1.1%
Mtengo: ≤0.1%
Pb: ≤0.1%
C46400 ndi yozizira kwambiri nthawi yozizira ndipo ndiyoyenera kukanikiza kotentha. Ili ndi machinability yabwino ndipo ndi yosavuta kuwotcherera ndikuwotcherera, koma imakhala ndi chizolowezi chowononga ndi kusweka (kuphulika kwanyengo). C46400 malata amkuwa amagwiritsidwa ntchito popanga zombo kupanga zida zomwe zimakumana ndi madzi am'nyanja, mafuta, ndi zina zambiri.
Chifukwa cha kusiyana pang'ono pakati pa miyezo, ngati chingwe chamkuwa cha China / ndodo yamkuwa /mbale zamkuwa, nthawi zambiri timagwiritsa ntchito HSn62-1 m'malo mwa C46400/C46200/C4621. Zomwe zili mkuwa za C46200 ndizokwera pang'ono.
C48500(QSn4-3) ndi mkuwa wotsogola kwambiri. Zomwe zimatsogolera ndizokwera kuposa magiredi awiri omwe atchulidwa pamwambapa. Zigawo zake zazikulu ndi izi:
Mkuwa (Cu): 59.0% ~ 62.0%
· Kutsogolera (Pb): 1.3% ~ 2.2%
Chitsulo (Fe): ≤0.10%
malata (Sn): 0.5%~1.0%
Zinc (Zn): Balance
Phosphorous (P): 0.02%~0.10%
Ili ndi elasticity yabwino, kukana kuvala komanso anti-magnetism. Ndi oyenera kukakamiza kukonzedwa m'madera ozizira komanso otentha. Ndi yosavuta kuwotcherera ndi braze. Ili ndi makina abwino komanso kukana kwa dzimbiri mumlengalenga, madzi abwino ndi madzi a m'nyanja. Nthawi zambiri amagwiritsidwa ntchito pazinthu zosiyanasiyana zotanuka, zoyikapo zitoliro, zida zamankhwala, zida zosagwirizana ndi maginito komanso zida zotsutsana ndi maginito.
