C103 | Cu-HCP is used in applications with a demand for high electrical and thermal conductivity. Also in the use of parts to weld or weld. It is also used for plating. Application examples: devices for electricity and electronics, die casting of die bars for brazing.

Good persistence in the natural atmosphere (also in marine air) and in the industrial atmosphere (dark res., Green spots on the surface), tap and drinking water, aqueous and alkaline solutions (without oxidant), pure steam, non-acidic oxidants (as far as there is no oxygen). in solution) and neutral solutions of salts.

The C103 | Cu-HCP can be tempered in an atmosphere containing hydrogen without risk of embrittlement. Intensity against stress corrosion cracking. Without persistence in solutions of cyanides, halides and ammonia, oxidizing acids, liquid ammonia, halogen gas, hydrogen sulfide and water.

The C103 | Cu-HCP is a low purity, high level residual phosphorus deoxidized copper. It has a very high electrical and thermal conductivity, good soldering and soldering properties, as well as resistance to hydrogen. It has excellent hot and cold forming properties, and good corrosion resistance in water and especially in the atmosphere (including the industrial atmosphere).

Applications

Electric
High frequency cable, submarine cable strips, waveguide tube, standard material for longitudinally welded cables, switches, applications requiring high conductivity, tube bus, electrical conductors, clad products, bus bars, terminals, thermostatic control tubes.

Industrial
Applications requiring good welding, applications requiring good weldability, pressure vessels, billet mold tube, extrusion cans for powder metallurgy.

The electrical conductivity is strongly influenced by the chemical composition. A high level of cold deformation and a small grain size decrease electrical conductivity moderately. Minimum conductivity level can be specified

Resistant to: Atmospheric corrosion: formation of a greenish protective patina due to the formation of basic copper salts (such as sulfates, chlorides in the marine environment, nitrates and carbonates)

Water (industrial and drinkable). Aqueous and alkaline solutions (non-oxidizing), pure water vapor (steam), non-oxidizing acids (without oxygen in solution), neutral saline solutions.

The material can be heat treated in a reducing atmosphere.

Insensitive to stress corrosion cracking.

Not resistant to: oxidizing acids, solutions containing cyanides, ammonia or halogens, hydrated ammonia and halogenated gases, hydrogen sulfide, sea water.
