1931-8-15 X-ray photographs of the alloys show that they are a homogeneous mixture of the copper and nickel crystals. Although copper is only weakly diamagnetic it requires 0.8 or 0.9 percent nickel to neutralize this diamagnetic effect and 56 percent nickel is required before the alloy shows ferromagnetic properties at ordinary temperatures.

2022-4-28 Copper and nickel are adjacent to one another in the periodic system of elements, with atomic numbers 29 and 28 and atomic weights 63.54 and 68.71.The two elements are closely related and are completely miscible in both the liquid and solid state. Cu-Ni alloys crystallise over the whole concentration range in a face-centred cubic lattice.

2022-5-5 Nickel (Ni) is ferromagnetic in nature, because of the parallel alignment of its 2 unpaired electrons or ‘spins’ in presence of an external magnetic field. Nickel holds its magnetic property even in absence of any magnetic field, which gives permanent magnetization to it. Nickel exists as a silvery-white lustrous metal with a tinge of gold.

Iron alloys containing copper and nickel were irradiated at 288 C to a fluence of 4.63 {times} 10{sup 19} neutrons/cm{sup 2}. Neutron irradiation produced defects which were observable by TEM in all of the iron alloys studied. The TEM analysis of the defects showed them to be interstitial dislocation loops with a and a/2 Burgers vectors.

Cupronickels are copper-nickel alloys that contain typically from 60 to 90 percent of copper and nickel as the main alloying element. The two main alloys are 90/10 and 70/30. Other strengthening elements, such as manganese and iron, may be also contained. Cupronickels have excellent resistance to corrosion caused by sea water. Despite its high copper content,
