Patent number: 5849113
Abstract: High temperature coefficient of resistance (TCR) appropriate for the sensor evices is attained by an alloy consisting, by atomic %, of from 5 to 65% of Fe, and from 0.01 to 20% in total of at least one auxiliary component selected from the group consisting of 20% or less of Ni, 20% or less of Co, 20% or less of Ag, 20% or less of Au, 20% or less of Pt, 10% or less of Rh, 10% or less of Ir, 10% or less of Os, 10% or less of Ru, 10% or less of Cr, 5% or less of V, 5% or less of Ti, 5% or less of Zr, 5% or less of Hf, 8% or less of Mo, 5% or less of Nb, 10% or less of W, 8% or less of Ta, 3% or less of Ga, 3% or less of Ge, 3% or less of In, 3% or less of Be, 5% or less of Sn, 3% or less of Sb, 5% or less of Cu, 5% or less of Al, 5% or less of Si, 2% or less of C, 2% or less of B, and 5% or less of a rare earth element, the balance being essentially Pd and minor amount of impurities, and said alloy having 4000.times.10.sup.-6.degree. C..sup.-1 or more of TCR in a temperature range of from 0.degree. to 200.
