Girobond NB

€145,00 + IVA

Girobond NB is an innovative adhesive alloy for the crown and bridge technique. The special, carbon-free composition of this CoCrMo alloy with its doping fines offers optimal properties and guarantees excellent results. Also suitable as a universal clasp prosthesis alloy for cast models, large telescopic work and delicate superstructures. Easy to eliminate by any method. Elaborate manufacturing using the precision casting process ensures quality advantages: protective cerium oxide coating, no discoloration, corrosion protection, improved metal-ceramic bond. Relatively soft alloy, easy to mill. Dense surface that can be easily polished to a mirror shine: Niobium acts as a fine-grain former when the melt solidifies. Carbon free and therefore without risk of cracking, easily laser welded. Problem-free and safe aesthetic veneering with all metal-ceramics; CTE of 14.6. Thanks to melt mirroring, no overheating of the melt.
