Critical Metals Conservation, Recycling and Substitution,

Abstract

In the recent past there has been increasing concern about disruptions in the price and supply of certain metals--the so-called critical elements--due to inadequate supplies to meet the demand, diminishing reserves, and political action or inaction. This paper broadly reviews the subject, identifying the critical metals relative to their current importance to the aerospace industry. The roles of conservation, recycling, substitution, stockpiling and market place operations are analyzed. New and emerging technologies are discussed relative to their effects on the critical metals, and finally some suggestions are presented for meeting future anticipated material supply problems.
