Tooj dag bar tsis-ferrous hlau ua tus pas nrig ntawm ib hom, nrog kev ua tau zoo dua, muaj hluav taws xob zoo. Cov pas nrig tooj dag raws li txoj kev tsim khoom tau muab faib ua txuas ntxiv mus txuas ntxiv cov pas nrig tooj liab thiab extruded tooj dag npas. Extruded tooj dag pas nrig yog qhov zoo dua li qhov tsis tu ncua cam khwb cia brass muaj qhov zoo tensile muaj zog, siab hardness. Feem ntau hauv cov tsheb mus, qhov chaw kho mob, feem ntawm cov khoom hluav taws xob thiab lwm yam precision tooj hauv qhov ntau ntau.
Tooj dag pas nrig yog ua los ntawm tooj liab thiab zinc alloy rau hauv pas nrig-zoo li khoom, muaj npe rau xim daj. Tooj dag nrog cov ntsiab lus tooj liab ntawm 56% rau 68%, nws lub ntsiab lus melting yog 934 rau 967 degrees. Tooj dag muaj cov neeg kho tshuab zoo thiab hnav-resistant yam ntxwv, thiab tuaj yeem siv los ua cov twj paj nruag, qhov chaw ntawm cov plhaub plhaub rau phom. Cov ntsiab lus Zinc txawv kuj tseem yuav muaj cov xim sib txawv, xws li zinc cov ntsiab lus ntawm 20% {{{% yuav yog brownish daj. Tsis tas li ntawd, tooj dag muaj lub suab tshwj xeeb thaum ntaus, yog li cov neeg ua si nyob rau sab hnub tuaj nyob rau sab hnub poob, yog txhua yam ua los ntawm tooj dag.
