    Permalloy is a highly magnetic nickel-molybdenum-iron alloy, with roughly 80% nickel and 15% iron and 5% molybdenum content. It's useful as a magnetic core material in electrical and electronic equipment. Commercial permalloy alloys typically have relative permeability of around 100,000, compared to several thousand for ordinary steel. If provide maximum magnetic permeabilities and minimal core losses at low field strengths. This vacuum-melted product also offers the advantages of small size and weight in magnetic core and shielding materials for the applications shown below. Other magnetic properties are near zero magnetostriction, and significant anisotropic magnetoresistance. 

     

    Permalloy provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction which is critical for industrial applications, allowing it to be used in thin films where variable stresses would otherwise cause a large destructive variation in magnetic properties. Typical applications for this material are:

    ·         Transformer laminations                   

    ·         Relays

    ·         Recording Heads

    ·         Deflection and Focusing Yokes

    ·         Amplifiers

    ·         Loudspeakers

    ·         Shielding

    NOTE:

    1.       Saturated magnetic induction, Bs, is measured under 2000~2400 A/m applied magnetism for 1J34, 1J51, 1J52 and 1J403.800 A/m for 1J65, 1J67

    and1J83.

    2. Iron loss P1/400 and P1/300 represent iron loss when peak magnetic induction reaches 1T at 400 Hz and 300 Hz, respectively.

    3. Bm in Square coefficient Br/Bm represents magnetic induction strength under 80 A/m applied magnetic strength.

    Note: we could do any other products with specified technical standard, say, ASTM,SAE,DIN,S.E.W.,JIS,ISO,IEC,NF,BS,ΓОСТ.PLS contact us for more information: Tel: +86-29-89396652 or e-mail us at: Sales@xaleipeng.com
