Nervalloy-SX is a palladium-copper alloy threaded with continuous SNT-derived neural filament pathways that are grown in situ during fabrication, producing a structural metal capable of transmitting electrochemical signals at biological speeds alongside conventional electrical current. The neural pathways integrate bidirectionally with host nervous tissue at implant interfaces, allowing augment systems built from Nervalloy-SX to communicate with the body's proprioceptive and motor networks without external signal converters. Apex Nanofabrication holds the manufacturing patent, though BioForge Labs supplies the SNT filament stock that makes the material viable.
