Abstract of the Invention A corrosion-resistant dental alloy is disclosed which has improved handling characteristics during the filling of a dental cavity. The alloy particles are characterized by having a higher than average silver and copper content at the surface, by their unique shape differing from either flake or spherical alloys, and a surface area of about 0.23-0.26 m2/gm. Handling characteris- tics of an amalgam prepared from such an alloy is similar to those of flake-like particles and differs from amalgams prepared from spherical particles as quantified by newly-described physical tests which have been found to correlate subjective experience. The alloy particles may be combined with other particles having conventional shapes to produce amalgams having handling characteristics required by the user.
