Product Information
ERNiCu-7 (SNi4060)-Nickle Alloy Wire
Technical Compliance: AWS 5.14 Class ERNiCu-7 / ASME SFA 5.14 Class ERNiCu-7
Product Overview
ERNiCu-7 is a premium nickel-copper alloy designed to deliver exceptional corrosion resistance in extreme chemical and aqueous environments. Its unique composition enables superior performance in fluorinated gases, acids, and marine conditions, making it indispensable for industries where durability and reliability are critical.
Key Features & Benefits
Superior Acid Resistance
Fluorine & Fluoride Compounds: Resists attack from fluorine gas, hydrogen fluoride (HF), and their derivatives, where many materials fail.
Hydrochloric Acid (HCl): Performs reliably in HCl environments, maintaining structural integrity.
Sulfuric Acid (H₂SO₄): Withstands concentrations up to 85%, ideal for chemical processing and storage applications.
Hydrogen Fluoride (HF): One of the few materials capable of enduring HF exposure, ensuring safety in hazardous settings.
Outstanding Aqueous Corrosion Resistance
Marine Environments: Surpasses copper-based alloys in seawater resistance, with minimal corrosion rates (<0.025 mm/year).
Pitting & Stress Corrosion: Highly resistant to localized attack and stress-related failures, extending component lifespan.
Freshwater & Industrial Waters: Maintains low corrosion rates in diverse water conditions, reducing maintenance costs.
High-Temperature Stability
Air Exposure: Operates continuously at temperatures up to 600°C (1112°F) without significant degradation.
Steam Environments: Exhibits corrosion rates below 0.026 mm/year in high-temperature steam, ideal for power generation and heat exchangers.
Ammonia Compatibility
Anhydrous Ammonia: Resists corrosion in ammonia atmospheres at temperatures up to 585°C (1085°F), making it suitable for fertilizer production and refrigeration systems.
Applications
Chemical Processing: Reactors, pipelines, and storage vessels for acids, fluorides, and ammonia.
Marine Engineering: Seawater pumps, heat exchangers, and offshore structures.
Power Generation: Boilers, turbines, and steam systems exposed to high-temperature corrosion.
Oil & Gas: Downhole equipment and sour gas handling components.
Why Choose ERNiCu-7?
Proven Performance: Tested in the most corrosive environments, with data-backed reliability.
Cost-Effective: Reduces downtime and replacement costs by minimizing corrosion-related failures.
Versatile Fabrication: Available in multiple forms (welding wire, rods, sheets) for seamless integration into projects.
