Chromium Metal Powder Description
Chromium is a highly slightly dark gray metal. Ductile in the pure form, but in the impure form, chromium is hard and brittle. Its density is 7.20 g/cm³ and is soluble in concentrated alkaline solutions. Chromium has very good corrosion resistance; it oxidizes even in the red-hot state, slowly in air, and is insoluble in water. Chromium can be deposited on other metals to provide a protective coating. Chromium plating and diffusion treatment may coat substrates such as steel, copper, and aluminum with corrosion-resistant surface layers to achieve a shiny and beautiful surface.
Metallic chromium powder refers to powder in which there are mostly chromium metal particles. It is suited and commonly researched during chromium product fabrication, thermal spraying, and processing by powder metallurgy.

Our Chromium Powder Features
It has high purity, even particle size, complete surface structure, easy dispersion, enormous specific surface area, and high surface activity.
What Are the Uses of Chromium Powder
Heat-resistant and light-resistant coatings, can also be used as abrasives, pigments for glass and ceramics, catalysts in chemical synthesis. Tanning agents for leather, mordants, impregnating agents, and certain pigments for dyeing cloth are some applications of chromium alum and bichromates. Chromium plating and diffusion treatment can form bright and decorative corrosion-resistant surface layers on steel, copper, and aluminum metals with wide uses in the furniture, automotive, and construction industries. Chromium ore also finds widespread use in the production of refractory products.
