Cadmium is currently used in many military applications to provide corrosion protection. Since it has been identified as a hazardous material, cadmium has been targeted for complete removal from Army weapon systems. Unfortunately, there is no “drop-in” replacement for cadmium. Users must choose from a variety of alternatives to suit their specific needs. Because of these needs, the U.S. Army Tank-Automotive & Armaments Command’s (TACOM) Tank-Automotive Research, Development, & Engineering Center (TARDEC) created an Alternate Material Selection System for Cadmium (AMSS-Cd) to assist in the selection of alternative materials. The original version of the AMSS-Cd was created from available physical and performance data. Some areas were found where information is unavailable. TACOM-TARDEC sponsored three projects over the past year to update the AMSS-Cd where information is needed. These efforts included (1) evaluating cadmium replacements on electrical connectors, (2) evaluating cadmium alternatives for fastener applications, and (3) testing to discover possible chromate conversion coating replacements to enhance the performance of cadmium alternatives. This paper will present an overview of the AMSS-Cd and it’s use. The paper will also discuss the corrosion control aspects of Cadmium and Cadmium alternatives in more detail.
