CuETP is the most common copper. It is universal for electrical applications. CuETP has a
minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has
0.02% to 0.04% oxygen content (typical). Most ETP sold today will meet or exceed the
101% IACS specification. As with OF copper, silver (Ag) content is counted as copper
(Cu) for purity purposes. C11000C (Electrolytic Tough Pitch Copper) is an electrolytic
refined copper widely used for electrical and electronic applications. CuETP has the
properties required in all applications with a hydrogen-free atmosphere. In the presence
of H2 and heat all oxygen-bearing coppers suffer from so-called hydrogen embrittlement.
This is a chemical reduction of copper oxide by diffusing hydrogen leading to formation of
H2O within the microstructure, resulting in embrittlement of the grain boundaries. The
phosphorus of our copper content is very low, so that electrical conductivity is
comparable to the best performing materials. C1100 is an oxygen containing copper
which has a very high electrical and thermal conductivity. It has excellent forming
properties. Due to its oxygen content soldering and welding properties are limited. The
alloy is registered US EPA antimicrobial. Due to its high copper content of about 99% CuETP provides the full antimicrobial properties of copper to inhibit the growth of bacteria,
1
viruses and fungi which are in contact for a short period of time on copper containing
surfaces. Traditionally used ETP grade copper for electric applications, characterized by
its content of hard copper oxides (Cu2O) with sizes of 5÷10 µm, which, for very small
wire diameters, significantly decrease their ductility. Electrolytic Tough Pitch Copper is
not suitable for case hardening. This material can be bent, soldered, drilled, riveted, and
formed to almost any configuration. ETP Copper is available in round bar, squares, flat
rectangular (bus bar), and certain profile shapes.

Electrical conductivity is strongly influenced by chemical composition. A high level of cold
deformation and small grain size decrease the electrical conductivity moderately.
Minimum conductivity level can be specified [Ref: 316, 409, 410, 254, 340, 268, 344,

Comments
Calculated
* Chemical composition measured for wire rod (diameter 8.00 mm) obtained from
Contirod technology
Composition limits: 99.90 Cu min (silver counted as copper). Silver has little effect on
mechanical and electrical properties but does raise the recrystallization temperature and
tends to produce a fine-grain copper. Iron as present in commercial copper, has no effect
on mechanical properties, but even traces of iron can cause C11000 to be slightly
ferromagnetic. Sulfur causes spewing and unsoundness, and is kept below 0.003% in
ordinary refinery practice. Selenium and tellurium are usually considered undesirable
impurities but may be added to improve machinability. Bismuth creates brittleness in
amounts greater than 0.001%. Lead should not be present in amounts greater than
0.005% if the copper is to be hot rolled. Cadmium is rarely present; its effect is to
toughen copper without much loss in conductivity. Arsenic decreases the conductivity of
copper noticeably, although it is often added intentionally to copper not used in electrical
service because it increases the toughness and heat resistance of the metal. Antimony is
sometimes added to the copper when a high recrystallization temperature is desired

CuETP (C11000) is subjected to embrittlement when heated to 370 °C or above in a
reducing atmosphere, as in annealing, brazing or welding. If hydrogen or carbon
monoxide is present in the reducing atmosphere embrittlement can be rapid. Literature:

Other
C11000 has excellent corrosion resistance
to weathering and very good resistance to
many chemicals. It is often used
specifically for corrosion resistance. It is
suitable for use with most waters, and can
be used underground because it resists soil
corrosion. It resists non-oxidising mineral
and organic acids, caustic solutions and
saline solutions. Depending on
concentration and specific conditions of
exposure, copper generally resists: acids
mineral acids such as hydrochloric and
sulphuric acids; organic acids such as
acetic acid (including acetates and
vinegar), carbolic, citric, formic, oxalic,
tartaric and fatty acids; acidic solutions
containing sulphur, such as the sulphurous
acid and sulphite solutions used in pulp
mills. Alkalies fused sodium and potassium
hydroxide; concentrated and dilute caustic
solutions. Salt solutions aluminium
[Ref: 254, 342, 268, 347,
chloride, aluminium sulphate, calcium
344, 346, 417, 421, 66,
chloride, copper sulphate, sodium
267, 354]
carbonate, sodium nitrate, sodium
sulphate, zinc sulphate. Waters all potable
waters, many industrial and mine waters,
seawater and brackish water. The
corrosion resistance of C11000 is not
adequate for: ammonia, amines and
ammonium salts; oxidizing acids such as
chromic and nitric acids and their salts;
ferric chloride; persulphates and
perchlorates; mercury and mercury salts.
Copper may also corrode in aerated non
oxidising acids such as sulphuric and acetic
acids, although it is practically immune
from these acids if air is completely
excluded. Copper is not suitable for use
with acetylene, which can react to form an
acetylide which is explosive. C11000 is
considered to be immune to stress
corrosion cracking in ammonia and the
similar media which cause season cracking
in brass and other copper alloys.

Values shown in table are typical for all tough pitch, oxygen-free, phosphorus-deoxidized
and arsenical coppers. Copper does not exhibit an endurance limit under fatigue loading
and, on the average, will fracture in fatigue at the stated number od cycles when
subjected to an alternating stress equal to the corresponding fatigue strenght (see Fig.)
[Ref: 254]
Rotating-beam fatigue strength of Cu-ETP (C11000) wire, 2 mm in diameter, H80 temper

The fatigue strength is defined as the maximum bending stress amplitude which a
material withstands for 107 load cycles under symmetrical alternate load without
breaking. It is dependent on the temper tested and is about 1/3 of the tensile strength
