Electrolytic tough-pitch copper (Cu-ETP) is the standard oxygen containing pure copper grade. It is very commonly used
for electronics and electric engineering components in cases that high conductivity (100 % IACS) is requested and
mechanical strength may be low. Typical applications of Cu-ETP strip are stamping parts, transformer coils, cable strip
and heat sinks.

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 Rm.
Fatigue strength
Types and formats available
- Standard coils with outside
diameters up to 1,400 mm
- Traverse-wound coils with drum
weights up to 1.5 t
- Multicoil up to 5 t
- Hot-dip tinned strip
- Contour-milled strip
Dimensions available
- Strip thickness from 0.10 mm,
thinner gauges on request
- Strip width from 3 mm,
however min. 10 x strip thickness
Stress remaining after thermal relaxation as a function of Larson-
Miller parameter P
(F. R. Larson, J. Miller, Trans ASME74 (1952) 765–775) given by:
P = (20 + log(t))*(T + 273)*0.001.
Time t in hours, temperature T in °C.
Example: P = 9 is equivalent to 1,000 h/118 °C.
Measured on rolled to temper specimens parallel to rolling
direction.
Total stress relaxation depends on the applied stress level.
Furthermore, it is increased to some extent by cold deformation.
