MATERIAL OVERVIEW

Cadmium metal was discovered by German chemist Friedrich Stromeyer in 1817. While heating zinc carbonate Stromeyer noticed a discoloration that was not a reaction that he would have expected from the compound. Stromeyer suspected that some unknown impurity was causing the discoloration.  After further experimental investigation he was able to isolate the impurity; realizing that he had discovered a new element he named it cadmium.

In its pure form, cadmium is a silvery white, malleable metal with a bluish hue. In its' powdered form it is a grayish/white color. It is found naturally in the earth's crust and is a relatively rare metal, ranking 67th in abundance among the 90 naturally occurring elements on Earth. Cadmium occurs primarily in zinc, copper, and lead ores.Cadmium Sheet

The name cadmium originates from the Greek word kadmeia and from the Latin word cadmia. The metal has a very low melting temperature and tarnishes in moist air. The metal is ductile and very malleable. Cadmium is a high neutron absorber and as a result is used for neutron shielding in the nuclear industry.

At ESPI Metals we produce cadmium in a variety of forms. For nuclear shielding applications we roll cadmium sheet to widths of 24” and lengths of 10 feet or more. Cadmium sheet thicknesses range from as thin as 0.001”/0.025mm to 1”/25.4mm plate. Depending on the size requirement we either draw or extrude cadmium wire and rod in diameters from 0.010”/0.25mm to 1”/25.4mm. We also have cadmium available in ingot, shot and pellets.

ESPI HAS OVER SIXTY YEARS EXPERIENCE MEETING OUR CUSTOMER'S UNIQUE SPECIFICATIONS. CADMIUM IS NO EXCEPTION, WE CAN MANUFACTURE CADMIUM TO NEARLY ANY CUSTOM REQUIREMENT.
