AURIDENT's LH Gold Casting Alloy is a noble, fine-grain, type III crown and bridge gold alloy containing 20% gold, 20% palladium and 41% silver. Excellent restorations with a soft yellow color can be produced at a lower cost than higher gold-content alloys, without compromising quality. The low specific gravity of the alloy means more units per ounce. The alloy is easy to cast and work with, resistant to tarnishing, and can be efficiently used by either high- or low-production laboratories. You also earn four Aurident Rewards Points for each ounce of LH alloy ordered.
