Effects of cold extrusion on the mechanical properties of scrapped copper coil

The recycling of copper coil into finished products via sand casting with subsequent cold extrusion was investigated. This paper examined the effects on mechanical properties scrapped using a locally manufactured extruder conventional face die. tested extrudates are limited to hardness, tensile, and compressive strength. results reveal that hardness extruded 11.10 mm 11.45 improved significantly by 39 % 41 %, respectively, compared respective non-extruded copper. tensile strength increases 42 22 for corresponding Also, elongation 33 34 respectively. It deduced is more ductile than micrograph reveals grains in relatively coarse nonuniform voids, but fine uniform obtained refined during extrusion, voids dislocations reduced significantly.
