Abstract
A novel high permeability alloy which excels in wear resistance, yet possesses a high permeability, and is particularly suitable for use in magnetic recording heads. The composition of the wear resistant, high permeability alloy of this invention includes a small amount (0.001-1 wt %) of boron added to an alloy known by the name of 'sendust' or a sendust-based alloy. The wear resistance of sendust or sendust-based alloys is greatly improved by the addition of boron.
