The isotopic abundance ratios of some elements which might be incorporated in grains formed in the winds of WC stars are calculated for 50, 100, and 150 M_sun; models. In particular, WC stars are copious producers of 41Ca, 107Pd, and 135Cs. Earlier in their evolution these stars also are expected to be major producers of 26Al. The results are compared with observations of anomalies produces by extinct radionuclides which have been detected in the early solar system material.
