PURPOSE:To obtain small-gage wire made of high tensile alloy, by a method wherein said alloy includes 0.0003 to 0.01wt% one or more kinds of rare earth elements such as La, Ce, Pr, ..., and Au and inevitable impurities as the rest components. CONSTITUTION:Alloy containing one or more kinds of elements from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Py, Ho, Er, Tm, Yb, Lu, Sc and Y of 0.0003-0.01wt%, and Au and inevitable impurities as the rest components has the advantage that it is not broken even when it is draw-processed to a small-gage wire having 0.05mm.phi less diameter. Accordingly, the wire made of this alloy is suitable for high speed connection of semiconductor elements, as it is not disconnected. Alloy should contain rare earth elements from 0.0003 to 0.01wt%, when less than 0.0003wt%, required high tensile strength is not achieved, and when more than 0.01wt%, brittleness is increased. |
