FeNi50 yumu\u015fak manyetik toz<\/strong> is the powder-metallurgy form of 50 percent nickel-iron permalloy, the alloy that occupies the practical middle ground of the Ni-Fe magnetic system: saturation induction of 1.5-1.6 T, roughly double that of high-nickel permalloys, combined with initial permeability of 5,000-10,000 and coercivity of 5-20 A\/m. Gas-atomized spherical powder is supplied in 15-45 um cuts for LPBF, 0-25 um for MIM, and insulated fractions for pressed powder cores, serving transformer laminations replacements, relay and solenoid cores, magnetic shielding, current sensors, and inductor cores at power and audio frequencies. Final magnetic performance requires a full hydrogen anneal after consolidation, which should be treated as an integral part of the manufacturing route.<\/p>\n\n\n\n

The composition sits at a deliberate compromise point in the nickel-iron system: nickel content high enough to keep the alloy FCC, ductile, and magnetically soft, but low enough to preserve the high saturation induction that falls off steeply as nickel rises toward the 78-80 percent of molybdenum permalloy.<\/p>\n\n\n\n
