Abstract

A process and a product produced thereby, for forming rod or bar or tube stock or strip, comprising a sheath and a densified dispersion strengthened metal core. Powdered dispersion strengthened copper is put into a metal can and compressively reduced to size and density. The relationship between the tensile strength of the core when fully densified and the cold worked tensile strength of the can is important to the nature of the product.
