ALUMINUM GLOSSARY - Airoldi Metalli

Compressive Strength
Strength to resist outside pressure (as distinguished, for example, from bending or stretching forces).
Concentricity
Conformance to a common center as, for example, the inner and outer walls of round tube.
Condenser Tube
The term Heat-Exchanger Tube is preferred, unless specific reference to a condenser application is
intended and purpose is to dissipate heat as efficiently as possible.
Conductivity
The ability of a substance to transmit heat, light or electricity. Aluminum has high electrical and thermal
conductivity, making it useful in a wide range of electrical and heat-exchanging applications.
Conduit
A tube used to protect electric wiring. See also Tubing, Electrical Metallic .
Conduit, Rigid
Conduit having dimensions of ANSI Schedule 40 pipe in standardized length and threaded ends.
Container
The steel cylinder, usually fitted with a removable liner, having an inside diameter slightly larger than the
billet to be extruded which holds and confines the billet during the extrusion cycle. Its length may vary
with the press tonnage rating and manufacturer.
Container Liner
The removable, replaceable cylindrical unit of press tooling which holds or confines the billet during the
extrusion cycle.
Container Seal
The interface between the container and the die. There must be sufficient clearance between the outer
edge of the die port and the inner edge of the container opening to prevent extrusion of the billet skin or
skull.
Container Wall Clearance
The difference in dimensions between the billet diameter and container liner internal diameter.
