    For silverware instead of BAg-9 when only one joint is needed. Fluidity decreased on copper and increased on silver due to dissolution of base metal. Easily wets nickel and iron alloys due to zinc content. Eutectiferous. White color, slightly more yellow than BAg-9. 25: 15: 60: Ag 71.5 Cu 28 Ni 0.5: Ag–Cu 780/795 [46] –

  3. Brazing - Wikipedia

    The center metal is often copper; its role is to act as a carrier for the alloy, to absorb mechanical stresses due to e.g. differential thermal expansion of dissimilar materials (e.g. a carbide tip and a steel holder), and to act as a diffusion barrier (e.g. to stop diffusion of aluminum from aluminum bronze to steel when brazing these two).

  8. Superhard material - Wikipedia

    en.wikipedia.org/wiki/Superhard_material

    Cubic boron nitride is insoluble in iron, nickel, and related alloys at high temperatures, but it binds well with metals due to formation of interlayers of metal borides and nitrides. It is also insoluble in most acids, but is soluble in alkaline molten salts and nitrides, such as LiOH, KOH, NaOH/Na 2 CO 3, NaNO 3 which are used to etch c-BN. [32]

  9. Charge carrier density - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier_density

    Since metals can display multiple oxidation numbers, the exact definition of how many "valence electrons" an element should have in elemental form is somewhat arbitrary, but the following table lists the free electron densities given in Ashcroft and Mermin, which were calculated using the formula above based on reasonable assumptions about ...
