Abstract
A marker for use in a magnetic anti-theft security system has an amorphous ferromagnetic alloy alarm strip and at least one activation strip. The semi-hard magnetic alloy for the activation strip contains 8 to 25 weight % Ni, 1.5 to 4.5 weight % Al, 0.5 to 3 weight % Ti and balance of iron. The alloy is distinguished over known, employed alloys by excellent magnetic properties and a high resistance to corrosion. Further, the alloy can be excellently cold-worked before the annealing.
