Advanced research in developing the alloy for World Work amalgam offers a high copper content and zinc free product. It is in line with ISO 24234:2015 standards and implements the best preparation techniques and guarantees optimum performance. The right mixture with Ag-Cu eutectic highlights a first class product in the preparation for NG2 amalgams. The micro-particle size of mixed irregular atomized and slaked blend, and the uniformity of the ratio in the metals, favor incomparable plasticity in its application. The optimum alloy and mercury ratio guarantees maximum corrosion and crack resistance, in addition to maintaining perfect edges. Features: - Ag ratio : 45 %. - Spill: Spill 2 .
