Dipti Metal Industries is a Leading ERNiCu-7 TIG Rod Manufacturer and Nickel-Copper Alloy Welding Wire Exporter in Mumbai, India, specializing in high-performance AWS A5.14 ERNiCu-7 GTAW filler metal under the DIPTIINOX® brand. This alloy is the standard consumable for welding **Monel® alloys 400, R-405, and K-500**, featuring a composition (Ni 62.0-69.0%, Cu Bal) that provides properties similar to Monel® 400. The weld metal exhibits **good strength** and **resists corrosion** in numerous environments, including **seawater, salts (brine), and non-oxidizing reducing acids** (e.g., hydrofluoric and de-aerated sulfuric acid). As a trusted Nickel Alloy TIG Rod ERNiCu-7 Supplier, we guarantee full conformance to AWS A5.14 for shipbuilding, chemical processing, and marine applications globally.
The AWS A5.14 ERNiCu-7 TIG Rod is a nickel-copper alloy filler metal primarily defined by its high nickel content (62.0-69.0%) and copper being the remaining balance. This specific composition is essential to ensure the weld metal closely matches the corrosion profile and mechanical strength of **Monel® 400** and related precipitation-hardenable alloys like **Monel® K-500**. It delivers a high-integrity weld that maintains resistance to **alkalies, salts, and non-oxidizing acids** over a wide temperature range. It is the go-to welding consumable for marine, chemical, and petrochemical industries, especially where exposure to **hydrofluoric acid** or high-velocity seawater is a concern. Our ERNiCu-7 rods, conforming to **UNS N04060**, ensure reliable, strong, and corrosion-resistant joints.

ERNiCu-7 TIG Rod is primarily used for welding Monel® Nickel-Copper alloys such as **Monel® 400, Monel® R-405, and Monel® K-500**. The weld metal (based on UNS N04060) provides properties similar to Monel® 400.
The filler metal has good strength and exhibits **excellent corrosion resistance** across many media, including aggressive environments like rapidly flowing seawater, salts (brine), and non-oxidizing **reducing acids**.
ERNiCu-7 is a Nickel-Copper alloy, where **Copper is the balance** of the composition. This high-copper content is essential for resistance in hydrofluoric acid and de-aerated sulfuric acid, distinguishing it from Ni-Cr-Mo alloys.
The typical Tensile Strength (UTS) of the **ERNiCu-7** weld metal in the as-welded condition is **530 MPa (77 ksi)**, with an elongation of 34%.
