Cadmium is a soft, ductile transition metal with moderate stiffness and density, historically valued for corrosion resistance and low melting point. It is primarily used in battery electrodes (nickel-cadmium cells), electroplating coatings, and pigments, though its application has declined significantly in developed economies due to toxicity and regulatory restrictions. Engineers select cadmium for specialized electrochemical systems and corrosion protection in demanding environments, but must carefully evaluate health and environmental compliance—many industries have transitioned to safer alternatives in consumer applications.
