StarBlaze TIG Wire ERNiCu7

STARBLAZE TIG ERNiCu-7 is a premium, high-performance nickel-copper alloy TIG welding rod engineered for high-integrity Gas Tungsten Arc Welding (GTAW).
Complying strictly with international standard AWS A5.14 ERNiCu-7, this solid wire matches the composition of Monel 400 alloys.
Formulated with titanium additions to suppress weld porosity, it delivers superb resistance to localized seawater corrosion, reducing acids, and brackish environments, making it a foundational choice for marine and heavy chemical engineering.

Product Overview & Composition
Alloy Classification: Conforms precisely to global guidelines
AWS/SFA A5.14: ERNiCu-7, UNS N04060, and EN ISO 18274: S Ni 4060.

Chemical Profile: Formulated with a rich Nickel (Ni) core (~65%) and Copper (Cu) remainder (~30%), balanced with 3% Manganese (Mn) and 1.5% to 3.0% Titanium (Ti).
Porosity Control: The vital inclusion of titanium acts as a powerful deoxidizer, binding residual gases to ensure completely porosity-free, radiographic-quality joint profiles.
World-Class Corrosion Defense: Outperforms standard stainless grades when combating fast-moving brackish currents, chlorinated solvents, salts, and reducing alkalis or sulfuric acids.

Target Applications & Material Compatibility
Because it effectively halts galvanic and stress-corrosion mechanisms, it is heavily used to bond:
Monel Alloys: Directly welds matching chemical bases like Monel 400, R-405, and K-500 to themselves.
Dissimilar Steel Combinations: Successfully bridges the joint gap when marrying nickel-copper alloys directly onto standard carbon steels, low-alloy steels, or copper-nickel configurations.
Overlay Cladding: Frequently applied to deposit a tough, corrosion-resistant Monel surface layer over raw structural carbon steel cores (often utilizing a pure nickel ERNi-1 buffer layer first).
