N.P.G.+2 is a Type III casting alloy with 2% gold for non-ceramic fixed appliances, full cast crowns, single units, onlays, medium-span multiple unit bridgework, metal sub-structure for veneer crowns using acrylic & composites as well as posts and cores. N.P.G.+2 has a 25% greater yield strength than standard NPG. The inclusion of gold in N.P.G.+2 means a higher resistance to masticatory force; making it an excellent metal sub-structure for any polymer based crown and bridge resin and all other non-ceramic crown and bridge applications. N.P.G.+2 is a safe and bio-compatible alloy that can be used with confidence. N.P.G.+2 provides patients with reliability, durability, value, and safety. Vickers hardness of 143.
