A non-discoloring palladium-based alloy, free of silver or gold, suitable for fusion to dental porcelain compositions consists essentially of 75 - 85% by weight of Pd, 5 - 10% by weight of In, 5 - 10.5% by weight of Sn, up to 7.5% by weight of Co, Cr or Ni and up to 0.25% by weight of Si. Inclusion of 0.2 - 0.7% by weight of Ru improves the physical and mechanical properties of the alloy.
