ED033908 - Lincoln Metalshield MC-90 .052 Metal Core Wire 500lb Drum

High-Performance Metal-Cored Wire for Critical Applications

The Lincoln Electric Metalshield® MC®-90 (SKU: ED033908) is a premium low-alloy, metal-cored welding wire designed specifically for high-strength fabrication requirements. Engineered to deliver a minimum tensile strength of 620 MPa (90 ksi), this consumable is the ideal choice for industries demanding structural integrity and reliability, such as heavy equipment manufacturing, structural steel construction, and automotive fabrication. The .052-inch diameter provides a balance of deposition efficiency and arc control, making it suitable for a wide range of joint configurations and material thicknesses.

Metal-cored wires like the MC-90 offer distinct advantages over traditional solid MIG wires. The composite core contains metallic powders that stabilize the arc, improve wetting action, and significantly increase deposition rates. This results in faster travel speeds and reduced cycle times, which is critical for industrial operations focused on throughput. Furthermore, the MC-90 formulation is designed to minimize spatter levels and reduce silica island formation, thereby lowering post-weld cleaning costs and enhancing overall operational efficiency.

This product is supplied in a 500lb drum, a packaging solution tailored for high-volume welding environments and robotic automation cells. The bulk packaging drastically reduces the frequency of changeovers compared to smaller spools, ensuring continuous arc-on time and maximizing productivity. The wire is designed to operate with Argon-based shielding gas mixtures, typically providing a smooth spray transfer mode that ensures deep penetration and consistent fusion. By choosing Lincoln Electric's Metalshield MC-90, facilities can ensure they meet rigorous mechanical property requirements while optimizing their welding processes for speed and quality.
