G-TECH 403

Primarily employed for joining and surfacing complex aluminum bronzes, particularly those with high Mn content, as well as steel and cast steel. Renowned for excellent seawater and general corrosion resistance, this alloy proves invaluable in the shipbuilding industry (propellers, pumps, and armatures) and the chemical industry (valves, slides, pumps), especially in applications facing chemical attacks combined with erosion. With a favorable friction coefficient, it's apt for surfacing on waves, gliding surfaces, bearings, and matrices. The weld deposit boasts exceptional mechanical properties, toughness, crack resistance, good chip removal machining, corrosion resistance, and is non-magnetic. Ensure thorough cleaning of the weld area (metallic bright). Preheat large weldments to approximately 150°C, and maintain low heat input, with the interpass temperature not exceeding 150°C.
