PURPOSE:To obtain the titled alloy with superior wear resistance and increased saturation magnetizability by restricting the composition of an alloy consisting of Co, Nb, Zr, Ti, Ta, Ru and Re. CONSTITUTION:An amorphous magnetic alloy with superior wear resistance and high saturation magnetizability is obtd. by providing a composition represented by a formula CoaTbT'c (where T is one or more among Nb, Zr, Ti and Ta, T' is Ru and/or Re, 75<=a<=94, 6<=b<=20, 0.1<=c<=5, and a+b+c=100). When T is Nb and Zr, the desired Zr content is <=14atom%. An amorphous alloy with <=10<-6> magnetostriction constant and high wear resistance can be obtd. by adding elements M and M' to said alloy so as to provide a composition represented by a formula CoaTbT'cMdM'e (where M is one or more amont Ni, Cr, Mo and W, M' is Fe and/or Mn, 0<d<=12, 0<e<=3, and a+b+c+d+e=100). |
