  • Copper-Nickel Alloys Properties Processing Applications

    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.

  • Properties and applications of electroless nickel

    Electroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a substrate without the use of electric current. It differs therefore from electro-plating which depends on an external source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate.
