Term Definition
BurnishingA fabrication method of securing a smooth finished surface by slight deformation with highly polished tools.
 
BurrA thin ridge of roughness left by a cutting operation such as slitting, trimming, shearing, blanking, sawing, etc.
 
Burred EdgeA thin turned down edge on sheet or foil resulting from shearing.
 
Bursting PressureThe internal pressure required to burst tubes or other hollow products.
 
Bus BarA bus conductor of rectangular or square cross section of any dimension.

CastingAn article formed by solidification of molten metal in a mold.
 
CathodeIn corrosion processes, usually the metal that is not corroded.
 
Cathodic ProtectionReduction or prevention of corrosion of a metal surface by making it a cathode, for example by the use of sacrificial anodes or impressed currents.
 
CDAAbbreviation for Copper Development Association Inc.
 
CenterThe difference in thickness between the middle and edges of a sheet.
 
Chatter MarksA series of transverse ripples encircling a drawn product visible on outer or inner surfaces.
 
Chemical PropertiesThe properties of a material that describe its reactions with other substances, e.g. corrosion resistance.
 
Coating BlisterA blister in the coating of an alclad or clad product.
 
Coating StreakA surface blemish on rolled material resulting from aluminum oxide transferring from the roll to the sheet surface, giving a speckled appearance; known also as "roll-coating pickup".
 
Cobalt

Cobalt is a hard, lustrous, silver-gray metal, a chemical element with symbol Co. It is found in various ores, and is used in the preparation of magnetic, wear-resistant, and high-strength alloys. +

For more information on cobalt see our Encyclopedia Page on this topic.

 
CoilA length of a product other than a flat rolled or flat drawn product, wound into a merchantable hoop-like bundle.
 
Cold ShortnessThe characteristic of metals that are brittle at temperatures below the recommended hot working temperature ranges.
 
Cold WorkingThe process of changing the form or cross-section of a piece of metal at a temperature below the softening or recrystallization point, but commonly at or about room temperature. It includes rolling, drawing, pressing and stretching.
 
Collapsing PressureThe external hydrostatic or pneumatic pressure required to collapse a tube or other hollow article.
