Fossil fuels contain 0.5 to 1.5 ppm cadmium, but phosphate fertilisers contain from 10 to 200 ppm cadmium (Cook and Morrow 1995). 3.3.3 Cadmium Emissions to …

  • Cadmium Plating

    Cadmium Electroplating (Nadcap Accredited). Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacial coating," corroding before the substrate material.
