| Electrical conductivity |
Electrical conductivity or specific conductivity is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity is defined as the ratio of the current density to the electric field strength. |
| Elongation |
The percentage increase in distance between two gauge marks that results from stressing the specimen in tension to fracture. |
| Equivalent Round |
The diameter of a circle having a circumference equal to the outside perimeter of other than round tube. |
| Extrusion |
A product formed by pushing material through a die. |
| Extrusion Ingot |
A solid or hollow cylindrical cast form suitable for extruding. |
| Extrusion Ingot, Drilled |
A solid extrusion ingot which has been drilled to make it hollow. |
| Extrusion Ingot, Reamed |
A hollow extrusion ingot which has been machined to remove the original inside surface. |
| Extrusion Ingot, Scalped |
A solid or hollow extrusion ingot which has been machined to remove the original outside surface. |
| Extrusion Seam |
A seam in tube, pipe, or hollow shapes resulting from the pressure bonding at two or more edges in the course of extruding through a spider or porthole die. |
| Fin Stock |
Coiled sheet or foil in specific alloys, tempers and thickness ranges suitable for manufacture of fins for heat exchanger applications. |
| Finish |
The characteristics of the surface of a product. |
| Foil |
A rolled section rectangular in cross section of thickness less than 0.006 inch. |
| Forging |
A metal part worked to a predetermined shape by one or more such processes as hammering, upsetting, pressing, rolling, etc. |
| Forging Stock |
A wrought rod, bar, or other section suitable for forging. |
| Friction Scratches |
Short longitudinal scratches introduced during coiling or reeling of sheet or foil by relative movement between adjacent wraps of the coils. |
