Abstract
Amorphous Nickel-base alloys for electrical resistors, which contain, by atomic %, 81-x% Ni, x% Cr, 6% B and 13% Si (z=0.about.25), or 70% Ni, 11% Cr, 19-y% B and y% Si (y=0.about.19 except 13), or 100-z% of 0.864 Ni and 0.136 Cr and z% of 0.316 B and 0.684 Si (x=15.about.25 except 19), and have a relatively high electrical resistivity and a small temperature coefficient of resistivity, are disclosed. Their resistance values can be adjusted by heat treatment and the thermal stability of them after heat treatment is very good in the conventional operating temperature range of electrical components.
