The world`s most widely used alloy.
With over 25 years of proven clinical performance in millions of restorations, Dispersalloy® is the world`s most widely used alloy. Its consistent mix of lathe-cut particles and silver-copper eutectic spheres virtually eliminates the Gamma-2 phase, yielding exceptional corrosion resistance and reduced ditching. And thanks to its patented self-activating capsules, no activation tool is needed. Dispersalloy® is also available in powder and tablets.
