Vanadium

Executive Standard : ASTM A 801 UNS R30005

Principal Design Features : Soft magnetic alloy, 49% Fe-, 9% Co, 2% V. Very easily cracked in forging.


Applications: This alloy is used in motor laminations, transducers, poles and cores as well as transformer and head laminations.


Forms : Rod Strip Plate


Heat Treatment : For optimum properties, it is essential that proper post work annealing be performed. Heat to 1540 F for 2 hours in pure hydrogen and cool slowly at a rate of 180 to 200 F per hour. Temperatures above 1600 F will cause damage to the material's potential properties.


Cold Working : This material has a very high work hardening rate.


Annealing This is a 49% Ni/ Co alloy with 2% vanadium. It possesses excellent magnetic and physical properties including high saturation flux density, low DC coercive force and high permeability at high inductions.
