Product Description Product Description IntroductionLORK is a alloy manufacturer with 20 years of manufacturing experience. Permalloy refers to ferro-nickel alloy, which has a wide range of nickel content between 35% and 90%. The most important feature of Permalloy is its high magnetic conductivity of weak magnetic field. Their saturated magnetic induction strength is generally between 0.6 and 1.0T.Permalloy is a nickel-iron magnetic alloy, with about 80% nickel and 20% iron content. it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields. Commercial permalloy alloys typically have relative permeability of around 100,000, compared to several thousand for ordinary steel. In addition to high permeability, its other magnetic properties are low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications, allowing it to be used in thin films where variable stresses would otherwise cause a ruinously large variation in magnetic properties. Permalloy's electrical resistivitycan vary as much as 5% depending on the strength and the direction of an applied magnetic field. Permalloys typically have the face centered cubic crystal structure with a lattice constant of approximately 0.355 nm in the vicinity of a nickel concentration of 80%. A disadvantage of permalloy is that it is not very ductile or workable, so applications requiring elaborate shapes, such as magnetic shields, are made of other high permeability alloys such as mu metal.Precision Soft Magnetic Alloy 1J79 Applications- high frequency and low voltage transformer, - leakage protection switch core, - common mode inductor core - current transformer core.Precision Soft Magnetic Alloy 1J79 Main Specifications ChinaJapanUSAGermanyFranceRussiaU.K.GBHEASTMYOUR ONE/YOURNF EN/NFGUESTBS EN/BS1J79(Ni79Mo4)PCHY-Mu80High magnetic permeability 767Anny-SterM79NMC-Permalloy Precision Alloy 1J79 Chemical Composition Material TypeCPSMnSiNiCrCoMoCuFe1J79≤0.03≤0.02≤0.020.60-1.100.30-0.5078.5-80.0--3.80-4.10≤0.20BalanceHigh starting magnetic conductivity soft magnetic alloy AC magnetic propertyMaterial TypeProcess TypeStrip ThicknessElastic magnetic conductivity at different frequencies when the magnetic field strength peak is 0.1A60Hz400Hz1KHz10kHzNot Less Than1J79Cold Roll0.02--14000(17.5)10000(12.5)0.05--15040(18.8)7520(9.4)0.1-18000(22.5)12000(15)-0.2-10000(12.5)6000(7.5)-0.35257040(8.8)--1J79 Physical PropertiesPropertiesMetricDensity (g/cm3)8.6Electrical resistivity at 20oC(mm2/m)0.55Coefficient of linear expansion(20oC~200oC)X10-6/oC10.3~11.5Saturation magnetostriction coefficient λθ/ 10-62.0Curie point Tc/ oC4501J79 Heat Treatment Method Mode of heat treatment 1J79Annealing mediaVacuum with a residual pressure not higher than 0.1Pa, hydrogen with a dew point of not higher than minus 40 oC.The heating temperature and rate1100~1150oCHolding time3~6Cooling rateWith 100 ~ 200 oC/ h cooled to 600 oC, rapidly cooled to 300oCDetectionProcessing Packaging & ShippingCompany ProfileFAQQ1: Do you accept the trial order ?A1: Yes,if we have the exactly size in stock.we can delivery even 1 piece/meter .Q2: Can I have free sample before making orders?A2: Yes,we can supply free sample as requirement,but buyer needs to pay the freight charges ,the freight fee will return to buyer after making order.Q3: How do you control the quality ?A3: MTC and PMI will be sent before shipment,any 3rd party inspection if need .Q4: How about your delivery time ?A4: Generally delivery time is 15 working days .Q5: How can I quickly get the price list ?A5: Directly click "chat now" or send us email with detail specifications,you will get the official price list in 1 hour .
