SUPRA 50 is an iron-nickel soft magnetic alloys with maximum saturation induction and high permeability.
Main applications are relays, gas safety, sensors, watches, shieldings.
The saturation flux density of about 16000 gauss (1.6 Tesla) combined with high magnetic permeability and low core loss makes this a versatile alloy with many potential applications.
SUPRA 50 has been used in laminated cores for instrument transformers, magnetic shields and cores for certain electronic and communications devices in which extremely high permeability at low magnetizing forces greatly increases the efficiency and effectiveness of the equipment.
Because of its high permeability, it has also been used in solenoid cores and sensitive relays that must respond to low magnetizing forces

Heat treatment
Standard hydrogen anneal
For maximum softness and optimum magnetic and electrical properties, K94840 should be annealed in an oxygen-free, dry hydrogen atmosphere with a dew point below -40°F (-40°C) for 2 to 4 hours at 2150°F (1177°C), followed by a furnace cool at a rate of 100/200°F (55/110°C) per hour down to 800°F (427°C) and at any rate thereafter.
Oil, grease, lacquer, and any other contaminants must be removed before annealing. During hydrogen annealing, the individual parts should be separated by a surface insulation media or an inert insulating powder, such as magnesium or aluminum oxide.
