Chromium is a microstrip blue silver-white metal with a relative atomic mass of 51.99, a density of 6.98 to 7.21 g / cm3, a melting point of 1875 to 1920 ° C, and a standard electrode potential of Ush / c, -0. 74V, the old "/c," -0.61V and P + s + + Cr + 1.33V, metal chromium in the air easily passivated, the surface layer of a very thin passivation film, which shows the precious metal nature.
Chromium layer peristaltic pump has a high hardness, according to the bath composition and process conditions, the hardness can be a wide range of 400 ~ 1200HV changes. Chrome layer has a good heat resistance, heating at 500 ℃ below its gloss, hardness were no significant changes in temperature greater than 500 ℃ began to oxidative discoloration, greater than 700 ℃ hardness began to decrease. The chrome-plated layer is a fraction of friction, especially the dry friction coefficient, which is the lowest among all metals. So the chrome layer has a good wear resistance.
Chromium layer has good chemical stability, in alkali, sulfide, nitric acid and most organic acids do not play a role, but can be dissolved in hydrochloric acid (such as hydrochloric acid) and hot sulfuric acid.
In the visible range, the reflectivity of chromium is about 65%, between silver (88%) and nickel (55%), and because of chromium does not change color, the use of long-term to maintain its ability to reflect better than silver and nickel
