HI PERM 49

Descriptions of High Permeability “49"® AlloyMolybdenum-Lanthanum-Wire

High Permeability “49" alloy is a 48% nickel-iron alloy which has a saturation flux density of approximately 15,000 gausses after hydrogen annealing. Hysteresis loss is very low in either DC or AC circuits in which the frequency is less than 400 cycles per second.

Following a low temperature hydrogen anneal at 1300/1400°F (704/760°C), alloy 49 exhibits constant permeability characteristics. Its initial permeability is approximately 500 gausses.

High Permeability “49"® Alloy Available Forms:

Bar, Casting, Forging, Tubular, and Wire

Specifications of High Permeability “49"® Alloy

ASTM A753 Alloy 2, IEC 404-8-6 (Alloy class E3), MIL-N-14411B (MR) (Composition 3 and 4)

Applications of High Permeability “49"® Alloy

Used for transformer cores, solenoid cores, and magnetic shielding. The alloy is available in 3 distinct grades, depending upon product form and intended end application. 1. Strip, Rotor Grade — with non-directional magnetic properties. 2. Strip, Transformer Grade. 3. Bar, wire, rod and general purpose (shielding) strip.
