Cadmium producers and users are hopeful that Congress will approve plans to sell 5 million pounds of surplus cadmium from the government stockpile. Cadmium has been in short supply since the latter part of 1962. At the end of 1963, inventories in the hands of producers had dropped to 750,000 pounds, compared with million pounds at the end of 1962.
