2% GOLD NPG+2—a premium, base metal type 3 casting alloy with 2% gold for fixed crowns, bridges and onlays. NPG+2 provides 25% greater yield strength than the original gold alternative, NPG. This inclusion of gold in NPG+2 translates into a higher resistance to masticatory force; making NPG+2 an excellent metal sub-structure for any polymer ...
