The purpose of this paper is to acquaint the reader with the advantages and disadvantages of utilizing aluminum as a material for construction of wearable ornaments. In high-purity form aluminum is soft and ductile. Most commercial uses, however, require greater strength than pure aluminum affords. This is achieved in aluminum first by the addition of other elements to produce various alloys which singly or in combination impart strength to the metal.... (1978)

These defects, along with their causes and prevention, are
briefly reviewed in this article.... (2002)
