Claims8
A composite wire made by a process comprising the steps of:
- feeding a core material into an extrusion die;
- extruding an extrudable corrosion resistant metal through the die;
- and
- contacting said extruded metal with said core material as said core material is fed through the die to coat said core material, wherein said extruded metal has a longitudinally oriented grain structure and uniform grain size.
