Safeni 52 is a soft magnetic iron-nickel alloy with high magnetic permeability, low coercive force, a low content of non-metallic inclusions and thermal expansion properties which make it suitable for glass-sealing applications.

Available in strip, round wire and profile forms, Safeni 52 can be used in many applications requiring superior surface properties, accurately defined thermal expansion and high magnetic permeability.

Safeni 52 is particularly suitable for glass-to-metal seals and has its most important application in reed switches. It is also used for thermostats in industrial applications, transistors, voltage regulators, timing devices, temperature sensitive resistors and high frequency relays.
