Cov pas nrig tooj dag yog cov khoom zoo li tus pas nrig ua los ntawm tooj liab thiab zinc alloys, npe rau lawv cov xim daj. Brass nrog cov ntsiab lus tooj liab ntawm 56% mus rau 68% muaj qhov melting point ntawm 934 txog 967 degrees. Brass muaj cov khoom siv zoo heev thiab hnav tsis kam, thiab tuaj yeem siv los tsim cov cuab yeej precision, nkoj qhov chaw, phom plhaub, thiab lwm yam.
Cov ntsiab lus zinc sib txawv kuj tseem yuav muaj xim sib txawv. Piv txwv li, yog tias cov ntsiab lus zinc yog 18% -20%, nws yuav yog xim daj daj, thaum yog cov ntsiab lus zinc yog 20% -30%, nws yuav yog xim av daj. Tsis tas li ntawd, tooj dag muaj lub suab tshwj xeeb thaum ntaus, yog li Eastern gongs, cymbals, tswb, trumpets thiab lwm yam suab paj nruag, nrog rau cov twj paj nruag Western yog txhua yam ua los ntawm tooj dag.

58-3 tooj liab pas nrig, 59-1 tooj liab pas nrig belongs rau dawb-txiav tooj dag, uas yuav muab faib ua ib puag ncig tus phooj ywg tooj dag pas nrig thiab zoo tib yam tooj dag pas nrig. Feem ntau, tiag 58-3 tooj liab rods thiab 59-1 tooj liab rods yog tsim los ntawm extrusion txheej txheem. Cov pas nrig tooj liab uas tsim los ntawm cov tib yam nruam casting tooj liab pas nrig tsis tuaj yeem ua tau raws li txhua qhov kev ua tau zoo. Cov pas nrig tooj liab ua los ntawm cov txheej txheem extrusion muaj lub zog tensile zoo, siab hardness thiab siab ncaj. Feem ntau, lawv tau siv ntau dua hauv cov khoom siv tooj liab xws li qhov chaw pib, cov khoom siv kho mob, thiab cov khoom siv hluav taws xob.
