COPPER ALLOY
DATA SHEET
C11000
Electrolytic Tough Pitch
Copper (ETP) C11000 has a minimum copper plus silver content of 99.90% with
about 200-600 ppm (0.02-0.06%) oxygen present as cuprous oxide. This copper is noted for its high electrical
and thermal conductivity, good corrosion resistance and solderability, and
characteristic copper color.
When C11000 is exposed to
the outdoors for long periods, it produces a relatively impervious protective
film which eventually forms the familiar green patina of weathered copper. In most environments, its corrosion
resistance is excellent to good, although it is not suitable for use with
certain materials, for instance acetylene, ammonia, chromic acid, and nitric
acid.
Hot Working: C11000
has excellent hot workability, soft and ductile at a red heat.
Cold Working:
C11000 has excellent cold workability, having a high ductility only
slightly lower than that of the most ductile brasses. With increasing amounts of cold work, it work
hardens slowly, and therefore is capable of being worked extensively before
annealing is required. For drastic
operations like cold extrusion and drawing, the metal is usually supplied in
the soft condition.
Where less drastic working
is involved, light-drawn tempers are frequently used. The added stiffness of a light temper is
advantageous in feeding automatic machines such as cold-headers and for
machining. Where highest strength and
hardness are desired in the finished product, it is best to start with the
hardest temper adaptable to the forming operations involved.
Joining and Fabrication: Joining by soldering is excellent, while good
by brazing. Soldering can be done by all
heating methods. Brazing in
hydrogen-bearing atmospheres is not recommended due to potential hydrogen
embrittlement in which the hydrogen from the atmosphere combines with the
oxygen in C11000 to form water vapor. An
inert or oxidizing atmosphere is best.
Induction and salt-bath brazing are also suitable. Sound welds with good strength
can usually be made with the inert-gas arc welding, although these processes
are generally not recommended for C11000 copper.
Applications:
Applications of C11000 are numerous, and include ball floats, building
fronts, bus bars, conductivity wire, contacts, cotter pins, downspouts,
flashing, gaskets, gutters, kettles, nails, pans, printing rolls, radiators,
radio parts, rivets, screening soldering copper, switches, tacks, and
terminals.
Applicable Specifications: When so specified, C11000 will be
