| Term | Definition |
|---|---|
| Concentricity |
Conformance to a common center as, for example, the inner and other walls of round tube. |
| Conveyor Marks |
Scratches and pits occurring on one side of a sheet as a result of contact with cables or other means of conveyance. |
| Copper |
Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. It is a ductile metal with excellent electrical conductivity, and finds extensive use as an electrical conductor, thermal conductor, as a building material, and as a component of various alloys. |
| Core Blister |
A blister in the core of an alclad or clad product. |
| Corrosion |
The deterioration of a metal by chemical or electro-chemical reaction with it's environment. |
| CuBe |
See: Beryllium Copper |
| Cupronickel |
Cupronickel is an alloy of copper, nickel and strengthening impurities, such as iron and manganese. |
| Die Line |
A longitudinal depression or protrusion formed on the surface or drawn or extruded material due to imperfections on the die surface. |
| Diffusion Streak |
Surface streaks on an alclad or a clad sheet resulting from alloying constituents diffusing from the core into the coating during thermal treatment. |
| DMS |
A prefix for McDonnell Douglas's material specifications |
| DOD |
A prefix for the Department of Defense's material specifications. |
| Drawing |
The process of pulling material through a die, to reduce the size, change the cross section or shape, or to harden the material. |
| Ductility |
Ductility is the physical property of being capable of sustaining large plastic deformations without fracture (in metals, such as being drawn into a wire). It is characterized by the material flowing under shear stress. |
| Earing |
A characteristic of sheet to form ears when deep drawn or spun. |
| Eccentricity |
Deviation from a common center as, for example, the inner and outer walls of a round tube. The difference between the mean wall thickness and minimum or maximum wall thickness at any one cross section. The permissible degree of eccentricity can be expresssed by a plus and minus wall-thickness tolerance. |
