HIGH ELECTRICAL AND MECHANICAL CHARACTERISTICS 1)
Die forged copper provides better
mechanical characteristics than casting.
2) The mechanical
resistance of forged copper may be close
to that of standard steels.
3) Durability and resistance
to corrosion for use under
low, medium and high tension.
4) Copper is immediately
recyclable with a good value (environmental
benefit).
VARIOUS COPPER ALLOYS FOR NUMEROUS APPLICATIONS Cu-ETP
family:
Pure electrolytic copper (99.9%).
Cu-ETP is the ISO nomination (ETP: Electro Tough-Pitch)
(High conductivity for electrical components: switch…) Cu-OF
Family:
Natural copper without oxygen can be
thermally treated.
This copper may be easily assembled by various methods:
Welding or brazing alloy (welding components, connectors…) Cu-Te
P family:
Copper alloy comprising 0.3 to 0.7%
tellurium.
High suitability for machining thanks to the
dividing up of the chips (contact fingers,
plates…) Cu-Cr-Zr
family:
Resistant alloy comprising 0.5 to 1.2%
Chrome (anti-corrosion)
For application of electrical and thermal conductivity
(welding components, connectors and framework…) Cu-Ni-Si
family:
Copper alloy known as “Cupro-silicon” with 1 to 4% Nickel and 0.4 to 1.3% Silicon for applications requiring: high elastic resistance, robustness and durability (electrical couplers, catenary connectors, electrode support ..)

The
die forging of COPPER the benefit of performance
Conductivity: Quality of the ideal material
for any electrical applications.
-Low
tension: contact fingers, switches, connectors... - Medium
and high tension: transformer components...
Mechanical
resistance: The die forging of
copper has the benefit of
improved mechanical resistance. The
characteristics of certain alloys approach or
exceed those of steels currently in use (with
double the conductivity). Surface
treatment: Different treatment methods are easily applicable
to increase the performance of the compenents:
- Stripping
with sulphuric acid (matt finish / stripping
with nitric acid).
- Silver coating, tin, galvanisation...
Assembly: It
is possible to easily assemble the
copper components by:
- Brazing (after stripping/ in a neutral atmosphere) - Crimping
together, clipping…
Recycling:The recycling of copper is economical
(good value)
The copper recycling industry is high performance
and developed.
