Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm kev tsim cov khoom siv, nws tau siv dav hauv kev lag luam ntxiv cov ntsiab lus alloying rau tooj liab los ua.tooj liab alloysnrog txhim khu kev qha.Brass yog tooj liab alloy nrog zinc ua lub ntsiab alloying, uas muaj cov khoom siv zoo thiab yooj yim rau kev ua.Nws muaj qhov zoo corrosion tsis kam rau huab cua thiab dej hiav txwv.Raws li hom alloying ntsiab muaj, nws tuaj yeem muab faib ua tooj dag zoo tib yam thiab tooj dag tshwj xeeb;Raws li cov txheej txheem ntau lawm, nws tuaj yeem muab faib ua cov xov tooj ua tiav thiab cam khwb cia tooj dag.
Raws li cov tooj dag zoo tib yam, cov ntsiab lus xws li Sn, Si, Mn, Pb, thiab Al yog ntxiv los ua cov hlau alloy.Nyob ntawm cov ntsiab lus ntxiv, lawv hu ua tin tooj dag, silicon tooj dag, manganese tooj dag, txhuas tooj dag thiab txhuas tooj dag.Lub siab ua tiav qib tooj dag: H + nruab nrab cov ntsiab lus tooj liab.Piv txwv li: H62 txhais tau tias zoo tib yam tooj dag muaj 62% tooj liab thiab tus so yog Zn;cam khwb cia tooj dag suav nrog cov tooj dag zoo tib yam thiab cov qib tshwj xeeb tooj dag: ZCu + lub ntsiab cim cim + lub ntsiab lus tseem ceeb + lub cim cim thiab cov ntsiab lus ntawm lwm cov ntsiab lus ntxiv.
Cupronickel - tooj liab alloy nrog npib tsib xee ua lub ntsiab alloying.Nws muaj cov khoom txias thiab kub ua haujlwm zoo, thiab tsis tuaj yeem ua kom muaj zog los ntawm kev kho cua sov.Nws tsuas tuaj yeem txhim kho los ntawm kev daws teeb meem ntxiv dag zog thiab ua haujlwm hardening.Qib: B + nickel cov ntsiab lus.Qib Cupronickel nrog ntau tshaj peb yuan: B + lub cim ntawm lub ntsiab ntxiv thib ob thiab cov lej ntawm cov khoom tshwj tsis yog lub hauv paus ntsiab lus tooj liab.Piv txwv li: B30 txhais tau tias cupronickel nrog Ni cov ntsiab lus ntawm 30%.
