Qhov sib txawv tseem ceeb ntawm alpha alpha-beta thiab beta tooj dag yog tias alpha tooj dag muaj cov qauv siv lead ua homogenous nrog tsawg dua 36% zinc cov ntsiab lus, thiab alpha-beta tooj dag muaj cov qauv siv lead ua sib txawv nrog ib ncig ntawm 35-45% zinc. cov ntsiab lus, whereas beta tooj dag muaj cov qauv homogenous nrog txog 45-50% zinc ntsiab lus.
Brass yog tooj liab-zinc alloy; nws cov ntsiab lus zinc yog txog li ntawm 45% ntawm qhov hnyav. Feem ntau, manufacturers ntxiv tin, aluminium, silicon, manganese, npib tsib xee, thiab ua rau tooj dag ua ntxiv alloying ntsiab. Peb tuaj yeem tau txais cov khoom tsim nyog ntawm tooj dag los ntawm kev sib txawv ntawm cov feem pua ntawm cov muaj pes tsawg leeg. Vim nws qhov zoo tshaj plaws castability thiab tus nqi qis, tooj dag yog feem ntau cov tooj liab alloy.
Zinc hauv tooj dag ua rau nws muaj zog thiab pheej yig dua tab sis txo cov hluav taws xob conductivity thiab tiv taus corrosion. Tsis tas li ntawd, hloov cov zinc feem pua muab qhov kev hloov pauv ntawm cov xim hauv tooj dag. Vim nws cov xim daj / kub ntawm tooj dag, lawv muaj txiaj ntsig zoo rau kev kho kom zoo nkauj. Malleability yog ib qho ntawm cov khoom tseem ceeb ntawm tooj dag. Vim li no, tooj dag tuaj yeem thinned tawm mus rau cov ntawv zoo heev. Malleability nyob ntawm cov ntsiab lus zinc ntawm tooj dag. Brass nrog cov ntsiab lus siab zinc yog tsawg malleable. Tsis tas li ntawd, cov coefficient ntawm kev sib txhuam ntawm tooj dag yog tsawg. Cov cuab yeej no ua rau tooj dag haum rau cov ntawv thov kev sib txhuam qis.
Alpha Brass yog dab tsi?
Alpha tooj dag yog ib hom tooj dag uas muaj tooj liab siv lead ua qauv nyob rau hauv lub ntsej muag nruab nrab cubic qauv thiab zinc cov ntsiab lus txog li 36%. Nws yog ib qho khoom nrog zoo mechanical zog thiab zoo heev corrosion kuj. Txawm li cas los xij, nws muaj qhov hluav taws xob qis dua piv rau tooj liab. Hom tooj dag no muaj txiaj ntsig zoo hauv ntau yam khoom siv engineering xav tau rau kev sib tsoo, nias, thiab lwm yam.
Alpha-Beta Brass yog dab tsi?
Alpha-beta tooj dag yog ib hom tooj dag uas muaj zinc cov ntsiab lus siab thiab raug rau dezincofication corrosion yooj yim. Nws feem ntau muaj 35-45% zinc. Hom tooj dag no muaj txiaj ntsig zoo hauv kev ua haujlwm kub thiab kev siv extrusion.
Beta Brass yog dab tsi?
Beta tooj dag lossis beta theem ntawm tooj dag yog ib hom tooj dag uas muaj cov qauv tooj liab hauv lub cev-centred cubic qauv, thiab cov ntsiab lus ntawm zinc yog li 45-50%. Nws yog ib qho nyuaj ntawm tooj dag thiab tawv heev ntawm chav tsev kub. Hom tooj dag no muaj txiaj ntsig zoo hauv kev siv casting.
Qhov txawv ntawm Alpha Alpha-Beta thiab Beta Brass yog dab tsi?
Muaj ntau hom tooj dag, xws li alpha, alpha-beta thiab beta tooj dag. Qhov sib txawv tseem ceeb ntawm alpha alpha-beta thiab beta tooj dag yog tias alpha tooj dag muaj cov qauv siv lead ua homogenous nrog tsawg dua 36% zinc cov ntsiab lus thiab alpha-beta tooj dag muaj cov qauv siv lead ua heterogeneous nrog ib ncig ntawm 35-45% zinc cov ntsiab lus, whereas beta tooj dag muaj ib homogenous qauv nrog txog 45-50% zinc ntsiab lus. Ntxiv mus, alpha tooj dag muaj lub ntsej muag-centred cubic qauv thaum alpha-beta tooj dag muaj kev sib xyaw ntawm lub ntsej muag-centred cubic qauv thiab lub cev-centred cubic qauv, whereas beta tooj dag muaj lub cev-centred cubic qauv.

Summary – Alpha vs Alpha-Beta vs Beta Brass
Muaj ntau hom tooj dag, xws li alpha, alpha-beta, thiab beta tooj dag. Qhov sib txawv tseem ceeb ntawm alpha alpha-beta thiab beta tooj dag yog tias alpha tooj dag muaj cov qauv siv lead ua homogenous nrog tsawg dua 36% zinc cov ntsiab lus thiab alpha-beta tooj dag muaj cov qauv siv lead ua heterogeneous nrog ib ncig ntawm 35-45% zinc cov ntsiab lus, whereas beta tooj dag muaj ib homogenous qauv nrog txog 45-50% zinc ntsiab lus.
