Chromium yog ib hom silvery dawb hlau nrog zas xiav. Hlau chromium yog yooj yim passivated hauv huab cua, thiab ib zaj duab xis passivation heev yog tsim rau saum npoo, yog li qhia cov khoom ntawm cov hlau zoo. Lub chrome-plated txheej muaj qhov nyuaj siab. Raws li kev sib xyaw cov txheej txheem ntawm plating daws thiab txheej txheem txheej txheem, chrome-plated txheej tau zoo tiv tshav kub. Thaum rhuab hauv qab 500 ℃, tsis muaj qhov hloov pauv meej hauv qhov tseeb thiab tawv. Qhov kub siab tshaj 500 ℃ pib oxidize thiab hloov xim. , Lub hardness pib poob qis thaum nws siab tshaj 700 ℃. Kev sib txhuam coefficient ntawm chrome txheej yog me me, tshwj xeeb yog cov txhuam kev sib txhuam kom qhuav, uas yog qis tshaj plaws ntawm txhua cov hlau. Yog li no, chrome plating txheej tau zoo hnav tsis kam. Lub chromium txheej muaj tshuaj lom neeg ruaj khov. Nws tsis muaj kev cuam tshuam rau hauv alkali, sulfide, nitric acid thiab feem ntau cov organic acids, tab sis nws tuaj yeem yaj hauv hydrochloric acid (xws li hydrochloric acid) thiab sulfuric acid.
