Copper - Nickel Foil | Cu - ni Foil ( Cu70 / Ni30 ) For Electrical
Reaserching Of Elastic modulus of Copper - Nickel Foil
The biaxial elastic modulus was measured by bulge testing on Cu‐Ni
thin foils containing short‐wavelength composition modulations
produced by vapor deposition. In the wavelength range of 1.3–3.0
nm, we observed a twofold increase in the modulus as compared with
homogeneous foils. The increase was proportional to the square of
the composition amplitude. The maximum modulus occurred at a
wavelength of 1.7 nm and an average composition of 45 at. % Cu.
The stress‐strain curves of the modulated foils were reversible but
non‐Hookean, while homogeneous foils displayed a Hookean behavior
with moduli in good agreement with those calculated from the
singl‐crystal elastic constants of bulk Cu‐Ni alloys.
Standard Copepr Nlckel alloy with the following properties:
Low temperature coefficient of electrical resistance
High resistance to oxidation and corrosion
High strength with regard to breakage and bending cycles
The alloy is non-magnetic and the maximum temperature for use in
air is 600°C. The material is easy to work with and can be soldered
or brazed with no problems. All known welding processes can be
