CuETP is the most common copper. It is universal for electrical applications. CuETP has aminimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has0.02% to 0.04% oxygen content (typical). Most ETP sold today will meet or exceed the101% IACS specification. As with OF copper, silver (Ag) content is counted as copper(Cu) for purity purposes. C11000C (Electrolytic Tough Pitch Copper) is an electrolyticrefined copper widely used for electrical and electronic applications. CuETP has theproperties required in all applications with a hydrogen-free atmosphere. In the presenceof 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 ofH2O within the microstructure, resulting in embrittlement of the grain boundaries. Thephosphorus of our copper content is very low, so that electrical conductivity iscomparable to the best performing materials. C1100 is an oxygen containing copperwhich has a very high electrical and thermal conductivity. It has excellent formingproperties. Due to its oxygen content soldering and welding properties are limited. Thealloy is registered US EPA antimicrobial. Due to its high copper content of about 99% Cu-ETP provides the full antimicrobial properties of copper to inhibit the growth of bacteria,

2viruses and fungi which are in contact for a short period of time on copper containingsurfaces. Traditionally used ETP grade copper for electric applications, characterized byits content of hard copper oxides (Cu2O) with sizes of 510 m, which, for very smallwire diameters, significantly decrease their ductility. Electrolytic Tough Pitch Copper isnot suitable for case hardening. This material can be bent, soldered, drilled, riveted, andformed to almost any configuration. ETP Copper is available in round bar, squares, flatrectangular (bus bar), and certain profile shapes.Literature [Ref: 316, 409, 410, 411, 412, 413, 414, 325, 411, 254, 342, 340, 415, 268,347, 343, 345, 344, 143, 341, 346]

Electrical conductivity is strongly influenced by chemical composition. A high level of colddeformation and small grain size decrease the electrical conductivity moderately.Minimum conductivity level can be specified [Ref: 316, 409, 410, 254, 340, 268, 344,143]

[Ref: 567]
* Chemical composition measured for wire rod (diameter 8.00 mm) obtained fromContirod technology
Composition limits: 99.90 Cu min (silver counted as copper). Silver has little effect onmechanical and electrical properties but does raise the recrystallization temperature andtends to produce a fine-grain copper. Iron as present in commercial copper, has no effecton mechanical properties, but even traces of iron can cause C11000 to be slightlyferromagnetic. Sulfur causes spewing and unsoundness, and is kept below 0.003% inordinary refinery practice. Selenium and tellurium are usually considered undesirableimpurities but may be added to improve machinability. Bismuth creates brittleness inamounts greater than 0.001%. Lead should not be present in amounts greater than0.005% if the copper is to be hot rolled. Cadmium is rarely present; its effect is totoughen copper without much loss in conductivity. Arsenic decreases the conductivity ofcopper noticeably, although it is often added intentionally to copper not used in electricalservice because it increases the toughness and heat resistance of the metal. Antimony issometimes added to the copper when a high recrystallization temperature is desired[Ref: 316, 409, 412, 254, 415, 343, 344]

Corrosion resistance
Hydrogen embrittlement resistance
CuETP (C11000) is subjected to embrittlement when heated to 370 C or above in areducing atmosphere, as in annealing, brazing or welding. If hydrogen or carbonmonoxide is present in the reducing atmosphere embrittlement can be rapid.

C11000 has excellent corrosion resistanceto weathering and very good resistance to
many chemicals. It is often usedspecifically for corrosion resistance. It issuitable for use with most waters, and canbe used underground because it resists soilcorrosion. It resists non-oxidising mineraland organic acids, caustic solutions and
saline solutions. Depending onconcentration and specific conditions ofexposure, copper generally resists: acidsmineral acids such as hydrochloric andsulphuric acids; organic acids such asacetic acid (including acetates and
vinegar), carbolic, citric, formic, oxalic,tartaric and fatty acids; acidic solutions
containing sulphur, such as the sulphurousacid and sulphite solutions used in pulp
mills. Alkalies fused sodium and potassiumhydroxide; concentrated and dilute caustic
solutions. Salt solutions aluminiumchloride, aluminium sulphate, calciumchloride, copper sulphate, sodiumcarbonate, sodium nitrate, sodium
sulphate, zinc sulphate. Waters all potablewaters, many industrial and mine waters,
seawater and brackish water. Thecorrosion resistance of C11000 is notadequate for: ammonia, amines and
ammonium salts; oxidizing acids such aschromic and nitric acids and their salts;
ferric chloride; persulphates andperchlorates; mercury and mercury salts.Copper may also corrode in aerated non
oxidising acids such as sulphuric and aceticacids, although it is practically immunefrom these acids if air is completely
excluded. Copper is not suitable for usewith acetylene, which can react to form anacetylide which is explosive. C11000 isconsidered to be immune to stress
corrosion cracking in ammonia and thesimilar media which cause season cracking
in brass and other copper alloys.

Values shown in table are typical for all tough pitch, oxygen-free, phosphorus-deoxidizedand arsenical coppers. Copper does not exhibit an endurance limit under fatigue loadingand, on the average, will fracture in fatigue at the stated number od cycles whensubjected 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[Ref: 254]
The fatigue strength is defined as the maximum bending stress amplitude which amaterial withstands for 107 load cycles under symmetrical alternate load withoutbreaking. It is dependent on the temper tested and is about 1/3 of the tensile strength[Ref: 419].
