Kusiyana pakati pa mkuwa ndi mkuwa

Mkuwa umatchedwa mtundu wa buluu, ndipo mkuwa umatchedwa mtundu wake wachikasu.Kotero kwenikweni mtundu ukhoza kusiyanitsa pafupifupi.Kuti tisiyanitsidwe mosamalitsa, kusanthula kwa metallographic kumafunikanso.

Zobiriwira zakuda zomwe mwatchulazi zikadali mtundu wa dzimbiri, osati mtundu weniweni wa bronze.

Zotsatirazi zimabweretsa chidziwitso chofunikira cha ma aloyi amkuwa:

aloyi yamkuwa

Ma aloyi amkuwa amapangidwa powonjezera zinthu zina (monga zinki, tini, aluminium, beryllium, manganese, silicon, faifi tambala, phosphorous, etc.) ku mkuwa weniweni.Ma alloys amkuwa ali ndi madulidwe abwino amagetsi, matenthedwe amafuta ndi kukana kwa dzimbiri, komanso mphamvu yayikulu komanso kukana kuvala.

Kutengera kapangidwe kake, ma aloyi amkuwa amagawidwa mkuwa ndi mkuwa.

1. Brass ndi aloyi yamkuwa yokhala ndi zinki monga gawo lalikulu la alloying.Malingana ndi mankhwala, mkuwa umagawidwa kukhala mkuwa wamba ndi mkuwa wapadera.

(1) Brass Wamba Mkuwa wamba ndi aloyi yamkuwa ya zinki.Chifukwa cha pulasitiki yabwino, ndi yoyenera kupanga mbale, mipiringidzo, mawaya, mapaipi ndi mbali zozama kwambiri, monga mapaipi a condenser, mapaipi ozizira ndi makina ndi magetsi.Mkuwa wokhala ndi mkuwa wapakati pa 62% ndi 59% ukhozanso kuponyedwa ndipo umatchedwa cast brass.

(2) Mkuwa wapadera Kuti mukhale ndi mphamvu zapamwamba, kukana kwa dzimbiri ndi ntchito yabwino yoponyera, aluminium, silicon, manganese, lead, malata ndi zinthu zina zimawonjezeredwa ku aloyi yamkuwa-zinki kupanga mkuwa wapadera.Monga lead mkuwa, malata mkuwa, aluminiyamu mkuwa, pakachitsulo mkuwa, manganese mkuwa, etc.

Mkuwa wotsogolera umakhala ndi ntchito yabwino kwambiri yodulira komanso kukana kuvala bwino, ndipo umagwiritsidwa ntchito kwambiri popanga magawo a wotchi, ndipo umaponyedwera kupanga tchire lokhala ndi tchire.

Mkuwa wa malata umalimbana bwino ndi dzimbiri ndipo umagwiritsidwa ntchito kwambiri popanga zida zam'madzi.

Aluminiyamu mu mkuwa wa aluminiyumu imatha kupititsa patsogolo mphamvu ndi kuuma kwa mkuwa ndikuwongolera kukana kwake kwa dzimbiri mumlengalenga.Mkuwa wa aluminiyamu umagwiritsidwa ntchito popanga zida zolimbana ndi dzimbiri.

Silicon mu mkuwa wa silicon imatha kusintha mawonekedwe a makina, kukana kuvala komanso kukana kwa dzimbiri kwa mkuwa.Mkuwa wa silicon umagwiritsidwa ntchito makamaka popanga zida zam'madzi ndi zida zamakina amankhwala.

mkuwa

Mkuwa poyamba amatanthauza mkuwa-malata aloyi, koma makampani ntchito kuitana kasakaniza wazitsulo mkuwa munali zotayidwa, pakachitsulo, kutsogolera, beryllium, manganese, etc. komanso mkuwa, kotero mkuwa kwenikweni monga malata mkuwa, zotayidwa mkuwa, zotayidwa mkuwa, beryllium mkuwa, silicon bronze, lead bronze, etc. Bronze imagawidwanso m'magulu awiri: mkuwa wopangidwa ndi atolankhani ndi mkuwa.

(1) Tin bronze Copper-based alloy yokhala ndi malata monga cholumikizira chachikulu chimatchedwa malata bronze.Ambiri mwa malata amkuwa omwe amagwiritsidwa ntchito m'makampani amakhala ndi malata pakati pa 3% ndi 14%.Mkuwa wa malata wokhala ndi malata osakwana 5% ndioyenera kugwira ntchito mozizira;mkuwa wa malata wokhala ndi malata 5% mpaka 7% ndi oyenera kugwira ntchito yotentha;mkuwa wa malata wokhala ndi malata opitilira 10% ndi oyenera kuponyedwa.Mkuwa wa malata umagwiritsidwa ntchito kwambiri popanga zombo, makampani opanga mankhwala, makina, zida ndi mafakitale ena.Amagwiritsidwa ntchito kwambiri popanga zida zosagwira ntchito monga ma bearings ndi tchire, zotanuka monga akasupe, ndi anti-corrosion and anti-magnetic parts.

(2) Aluminiyamu bronze Copper-based alloy ndi aluminiyamu monga chinthu chachikulu cholumikizira chimatchedwa aluminium bronze.Zomwe zimapangidwa ndi aluminium bronze ndizokwera kuposa zamkuwa ndi malata amkuwa.Zomwe zitsulo zotayidwa zamkuwa za aluminiyumu zothandiza zimakhala pakati pa 5% ndi 12%, ndipo mkuwa wa aluminiyumu wokhala ndi 5% mpaka 7% uli ndi pulasitiki yabwino kwambiri ndipo ndi yoyenera kugwira ntchito yozizira.Pamene zitsulo zotayidwa ndi zazikulu kuposa 7% mpaka 8%, mphamvu imawonjezeka, koma pulasitiki imachepa kwambiri, choncho imagwiritsidwa ntchito kwambiri ngati-cast state kapena itatha ntchito yotentha.Kukana kwa abrasion ndi kukana kwa dzimbiri kwa aluminiyamu mkuwa mumlengalenga, m'madzi am'nyanja, m'madzi am'nyanja carbonic acid ndi ma organic acid ambiri ndi apamwamba kuposa amkuwa ndi malata amkuwa.Mkuwa wa aluminiyamu umatha kupanga magiya, tchire, magiya a nyongolotsi ndi zida zina zolimba kwambiri zosamva kuvala ndi zida zotanuka zokhala ndi dzimbiri.

(3) Beryllium bronze The copper alloy with beryllium as the basic element amatchedwa beryllium bronze.Mkuwa wa beryllium wa beryllium ndi 1.7% mpaka 2.5%.Beryllium bronze imakhala ndi malire otanuka komanso kutopa kwambiri, kukana kuvala bwino komanso kukana dzimbiri, kuyendetsa bwino kwamagetsi ndi matenthedwe amafuta, komanso imakhala ndi zabwino zopanda maginito, palibe spark ikakhudzidwa.Mkuwa wa Beryllium umagwiritsidwa ntchito makamaka popanga akasupe ofunikira a zida zolondola, zida za wotchi, mayendedwe ndi tchire zomwe zimagwira ntchito mothamanga kwambiri komanso kuthamanga kwambiri, komanso ma elekitirodi amakina opangira zida zowotcherera, zida zoteteza kuphulika, kampasi zam'madzi ndi mbali zina zofunika.
