Rolled Copper Foils rau roj teeb
Khoom Taw Qhia
Brass yog ib qho alloy ntawm tooj liab thiab zinc, uas feem ntau hu ua tooj dag vim nws cov xim daj daj.Cov zinc hauv tooj dag ua rau cov khoom siv tawv thiab tiv taus ntau duapuas, hos cov khoom kuj muajib qho zoo tensile zog.Cov ntawv ci tooj dag tsim los ntawmCIVEN METAL Nws muaj qhov zoo ntawm qhov chaw tiav, daim ntawv tiaj tus thiab zoo sib xws.Brass foil feem ntau yog siv rau hauv kev lag luam kho kom zoo nkauj vim nws cov tsos golden, raws li kev tiv thaiv los yog cov khoom siv ntxiv vim nws cov tawv tawv thiab kev cuam tshuam, thiab ua ib qhogasket khoomvim nws hnav tsis kam.Brass kuj feem ntau siv los ua cov khoom siv hluav taws xob cua sov vim nwshluav taws xobkuj muaj zog.Vim lub sphericalqauv ntawm cov dovtooj dag ntawv ci, lub xeev mos thiab tawv tuaj yeem tswj tau los ntawm cov txheej txheem annealing, ua rau nws tsim nyog rau ntau yam. daim ntawv thov.CIVEN METAL tuaj yeem tsim cov ntawv ci tooj liab nyob rau hauv txawv thicknesses thiab widths raws li cov neeg yuav tsum tau, yog li txo cov nqi ntau lawm thiab txhim kho kev ua hauj lwm efficiency.
