A magnetomechanical resonance element or marker strip with facilitated performance based on an amorphous magnetostrictive alloy ribbon having a line-like surface pattern is utilized in an electronic article surveillance marker or sensor element. A direction of magnetic anisotropy at angle between 80 and 90 degree away from ribbons length direction and in ribbons plane is introduced during ribbon fabrication, which increases the resonance performance with minimal loss in the magneto-mechanical circuit, and more particularly, in a marker or sensor element utilizing a plurality of resonating elements or marker strips. A marker or sensor element is fabricated utilizing the resonance element or elements and is utilized in an electronic article surveillance and identification systems.

A plurality of parts are brazed using an iron/chromium brazing filler metal. The parts are preferably composed of stainless steel and the brazed assembly forms a heat exchanger characterized by good corrosion resistance and low rates of leaching of Ni into fluids passing therethrough. The heat exchanger is especially suited for use in processing items intended to be ingested by humans or animals. Leaching rates and corrosion resistance are further enhanced by a post-brazing conditioning step wherein the assembly is heated in an oxygen-containing atmosphere to a temperature ranging from about 150 to 600C. The preferred iron/chromium brazing filler metal consists essentially of a composition having the formula Fe_(a)Cr_(b)Co_(c)Ni_(d)Mo_(e)W_(f)B_(g)Si_(h) wherein the subscripts a b, c, d, e, f, g, and h are in atom percent and wherein, b ranges from about 5 to 20, c ranges from 0 to about 30, d ranges from 0 to about 20, e ranges from 0 to about 5, f ranges from 0 to about 5, g ranges from about 8 to 15, h ranges from about 8 to 15, and the sum a+b+c+d+e+f+g+h=100, the balance being incidental impurities present in an amount up to about 1 percent by weight of the total composition.
