Properties of soft magnetic alloys
The nominal composition by weight %: ni:80-81, mo:4.5-6; si:0.050-0.40; mn:0-0.50; c:0.010; fe:bal
Soft magnetic alloys with mumetal grade , and high permeability, low magnetic losses characteristics
And applications like magnetic shielding & magnetic cores.
Soft magnetic alloys with permimphy grade, and high permeability-wear resistance & stamp ability characteristics have applications like magnetic head cores , high performance laminations.
Soft magnetic alloys with supermimphy grade, and high permeability,high purity improved corrosion resistance easier to heat treat characteristics have applications like high sensitivity relay parts for elcb ,high performance current transformer cores.
Applications
T.V shadow mask,material-invar [ni-35% min],invar is controlled thermal expansion alloys & it help to match holes of net of shadow mask for good focusing for clear picture.
T.V gun,invar [ni 42% min] is used for control thermal expension
Lng tank,invar [ni-36%min], gas is trransported at-163° c and closed atmospheric pressure and occuppied 600 times less volume.3,principle alloy characterstic- a low mean co-efficient of thermal expension between ambient temprature to [-163° c] i.E. Stable property after long expose at low tmeprature and thermal cycle and tank crack and leakage of gas can be controlled. Good weldability, bendability and complete absence of brittleness at low temprature.
Lead frame:used ifn electronic device as a i/c support / silicon chip,invar-n42 [ni-42%],it is also based on expansion behaviour and control thermal stress
Induction cooking: principle-the maxium working tmeprature is control by adopted ferromagnetic alloy with specific currie point set up temprature for cooking – [40-200]° c.
Magnetic shielding:soft magnetic alloys are used electrical engineering industries in order to concentrate a magnetic flux lines. As a consequence, an effective conversion or magnetic shielding can be achieved.
Magnetic alloys [ni 80% min] used for shielding.
Sensor:to detect a signal for electrical safety
Material-feni80mo5 / feni50
Bimetal:the bonding of two material, who’s co-offiecent of thermal expansion are controlled and permit the controlled of deflection
Applications: circuit breaker [electric safety],thermostats [temprature limiter]:automotive industry: thermal control of water cooled engines, electrical safety devices, controls panels.
Electronic irons, aquarium thermal control, boiling water machine,time limiter and control devices
Cigrettes lighters, toasters, flurescent lamps starters, staircase lighting switvhes, washing machine door control device
Miscellaneous: brakes mechanical compensation system , diesel thermal security pump device for cars and trucks [t > - 15°c], drum brake
