Chromium pieces are mainly for smelting. Two purity are available, 99% and 99.8%. It could be in other shapes too as lumps, ingots, sheets, rods, granules, wires and so on. Chromium is silvery white metal, which is hard and brittle. It is inactive metal and stable to oxygen and moisture at room temperature. Chromium pieces is of irregular small lumps. 99.99% and 99.95% Cr is product by hydrogen reduction process. 99.5%-99.8% Cr is product by carbon reduction process.

Chromium metal is mainly for hard alloys, diamond tools, welding materials, stainless steel, targets, vacuuming coating, thermal spraying and ceramics.
Chrome ingots apply to tough malleable steel, stainless steel and acid proof alloy. Pure chromium can apply to electroplate. It is raw material for high temperature alloys, electro-resistance alloys and precision alloys. It can improve hardness and corrosion resistance in alloy steels. In non-ferrous alloys, chromium lumps can improve high-temperature strength, fracture resistance, corrosion resistance and antioxidant.
