71045045 - Ampco-Trode 46 0.045 MIG Wire 30lb Spool ERCuNiAl

Industrial Grade Nickel-Aluminum Bronze Welding Wire

The Ampco-Trode 46 is a premium Nickel-Aluminum Bronze (ERCuNiAl) MIG welding wire designed for high-specification industrial and marine applications. This 0.045-inch diameter wire, supplied in a 30lb spool, is engineered to produce weld deposits with exceptional mechanical properties, including high tensile strength and superior yield strength. The alloy composition is specifically formulated to combat the harsh conditions found in maritime and heavy industrial environments, offering outstanding resistance to corrosion, erosion, and cavitation damage caused by turbulent seawater or chemical exposure.

Metallurgically, Ampco-Trode 46 excels in joining and overlaying operations. It is the filler metal of choice for welding cast nickel-aluminum bronze components, such as ship propellers, ship fittings, and pump housings. Its versatility extends to joining dissimilar metals; it is frequently employed to weld copper-nickel alloys to steel or to overlay steel components to provide a wear-resistant, corrosion-resistant surface. The deposit exhibits a hardness of approximately 180 Brinell (3000kg load), making it suitable for metal-to-metal wear applications where galling resistance is required.

For industrial procurement, this wire represents a critical consumable for MRO operations in shipyards, desalination plants, and chemical processing facilities. The consistent chemistry ensures reliable performance meeting AWS A5.7 specifications. The wire is precision-spooled to prevent tangling and ensure smooth feeding through automated or semi-automated MIG systems, reducing downtime during critical repair or fabrication tasks. Whether used for fabricating new components or reclaiming worn parts, Ampco-Trode 46 delivers a dense, defect-free weld deposit with mechanical integrity that rivals or exceeds the base metal.
