Copper Coated Mild Steel Wire – Low Spatter ER70S-6 MIG
Oct . 28, 2025 07:45
Copper Coated Mild Steel is a key solution in the Industrial equipment and supplies industry, specifically within Welding and cutting equipment and supplies and welding wire. This article explores how Dingzhou Jinlong Metal Production Co., Ltd. supports professionals with durable, high-performance products, and explains why this product is an ideal choice for businesses in these sectors.
Copper coated mild steel wire is the industry’s workhorse solid wire for GMAW/MIG and MAG welding of low carbon steels. The thin copper layer enhances electrical conductivity for stable arc starts, reduces contact-tip wear, and provides light corrosion protection for smoother wire feeding. In practice, this translates into excellent uptime on robotic cells and semi-automatic stations alike. A widely used classification is AWS A5.18 ER70S-6 (also written as aws sfa 5.18 er70s-6, aws 5.18 er70s 6, or a5 18 er70s 6). The “ER” denotes electrode/rod, “S” indicates a solid wire, and the “-6” identifies chemistry with higher deoxidizers (Si, Mn) that help weld over light mill scale and rust using CO2 or Ar/CO2 shielding gases.
Typical diameters range from 0.8 to 1.6 mm, supplied on plastic or metal spools and steel basket reels to suit different feeders and duty cycles. The aws er70s 6 MIG wire is valued for consistent penetration, high deposition rates, and clean weld beads with minimal post-weld finishing. Dingzhou Jinlong Metal Production Co., Ltd. manufactures copper coated mild steel wire with rigorous process control—covering drawing, copper coating uniformity, spooling tension, and layer winding—to deliver repeatable feeding and arc stability. For B2B buyers standardizing across plants, Jinlong’s reliable manufacturing ensures consistent performance batch to batch and simplifies qualification.
In fabrication shops, OEM assembly lines, and job sites, copper coated mild steel wire (welding wire aws er70s 6) is the go-to for structural steel, automotive components, heavy equipment frames, racking and storage systems, HVAC ducting, and general manufacturing. Its robust deoxidizer package supports welding over light surface contaminants, which is why aws er70s 6 MIG wire is frequently specified for high-throughput operations using 100% CO2 or mixed Argon/CO2 shielding. Consistent copper adhesion improves current transfer and feeding, helping reduce burnbacks and resulting downtime.
Key advantages include smooth arc characteristics, low spatter, and high deposition efficiency, yielding faster travel speeds and shorter cycle times. The wire aligns with widely recognized classifications—AWS A5.18 ER70S-6 / AWS SFA 5.18 ER70S-6—making specification and cross-plant standardization straightforward. A common question is: what does the 70 in the aws code er70s-6 represent? It indicates a minimum tensile strength of 70,000 psi (approximately 490 MPa) for the weld metal. Dingzhou Jinlong Metal Production Co., Ltd. supports both manual and automated cells with plastic and metal spools, tuned cast/helix, and low copper dusting to protect liners and contact tips—advantages B2B decision makers immediately see in throughput and quality KPIs.
Total cost of ownership for copper coated mild steel wire extends beyond the price per kilogram. With superior feedability and arc stability, users often see fewer stoppages, less rework, and reduced consumable spend (liners, contact tips), all of which drive ROI. Compared with uncoated alternatives, the copper layer can lower tip wear and help sustain consistent current, cutting spatter-related cleanup and boosting arc-on time. For multi-shift operations, larger spools or metal basket reels minimize changeovers and keep cells running longer between wire swaps.
Maintenance best practices include storing spools dry in their original packaging, using clean, properly sized drive rolls (V-groove for solid wire), and matching liners to wire diameter for minimal drag. Many customers in Welding and cutting equipment and supplies report steadier feeding with Dingzhou Jinlong’s copper coated mild steel wire, noting quick setup on both synergic and standard MIG/MAG power sources. By selecting a consistent aws er70s 6 supply—qualified to AWS A5.18 ER70S-6—buyers simplify WPS compliance and reduce variability, supporting predictable cost per weld.
Sustainability pressures and labor constraints are reshaping welding wire choices. Lower spatter and stable arcs mean less grinding and fewer rework passes—saving energy and consumables while improving ergonomics. For many plants, standardizing on a high-quality aws er70s 6 wire supports robotic adoption and lights-out manufacturing, critical trends in modern fabrication. Recyclable metal spools and optimized packaging help reduce waste across the supply chain, while process consistency curbs scrap, indirectly lowering emissions.
Dingzhou Jinlong Metal Production Co., Ltd. aligns with these market dynamics by focusing on process control, material traceability, and specifications that meet global norms such as AWS A5.18 ER70S-6. The company’s attention to copper coating uniformity and surface finish supports cleaner welding with less fume and spatter—key metrics in EH&S programs. For B2B procurement teams, working with a forward-thinking partner that can deliver consistent copper coated mild steel wire across plants and regions reduces operational variability and supports long-term sustainability goals.
Copper Coated Mild Steel wire remains the most dependable, widely specified solution for carbon steel MIG/MAG welding in Industrial equipment and supplies. With proven classifications like AWS A5.18 ER70S-6, it delivers stable arcs, low spatter, and high deposition—benefits that compound into measurable productivity and quality gains. Dingzhou Jinlong Metal Production Co., Ltd. is a reliable manufacturer offering consistent wire chemistry, uniform copper coating, and practical spool options for automated and manual applications.
