Characterization of Low and High Copper Amalgam Alloys and the Effect of Mixing Time on Their Physical Properties

Abstract

The available low and high copper amalgam alloys were characterized on the basis of their physical properties, as determined by A.D.A. Specification No.1. The effect of mixing time on these properties were also examined. Sufficient mixing following the manufacturer's direction is required for lathe-cut alloys, regardless of the copper content.
