FIELD: soldering fuel assemblies of nuclear reactors, mainly manufacture of spacing grids made of tubular blanks.
SUBSTANCE: alloy contains next relation of ingredients, mass %: iron, 4.0 - 6.0; beryllium, more than 3.0 - 4.0; niobium, 0.9 - 1.1; copper, 4.0 - 8.0; tin, 1.0 - 3.0; chrome, 0.2 - 1.0; bismuth + arsenic, 0.0001 - 0.0018; sulfur, 0.0001 - 0.0015; zirconium and inevitable impurities, the balance. Alloy may contain in addition germanium in quantity 0.25 -2.5 mass %.
EFFECT: increased corrosion resistance and creep resistance, lowered melting temperature, reduced quantity of iron intermetallides in soldered joint.
