Abstract

The paper describes the production of copper from a fibrous charge, including pressing, hot forging at 900°C, and subsequent cold deformation along the billet axis. Changes in density, strength, and plasticity are studied. Copper produced with this process meets standard requirements for cast and deformed rods. The process proposed includes fewer operations and requires less energy than the conventional recycling of scrap to obtain copper (remelting, refining, and metal forming).
