ED033905 - Lincoln Metalshield MC-90 .052 Metal Core Wire 33lb

High-Performance Low Alloy Metal-Cored Wire

The Lincoln Electric Metalshield MC-90 is a premium metal-cored wire engineered for high-strength welding applications requiring superior mechanical properties. Designed to meet the rigorous demands of heavy fabrication, this .052-inch diameter wire delivers a minimum tensile strength of 90 ksi (620 MPa), making it the ideal choice for welding high-strength low-alloy (HSLA) steels. As a metal-cored consumable, the MC-90 combines the high deposition rates of flux-cored wires with the high efficiency and low slag generation of solid wires, providing an optimal balance for industrial productivity.

Fabricators in the heavy equipment, automotive, and structural steel sectors rely on Metalshield MC-90 for its exceptional arc characteristics. The wire produces a stable, spray-type transfer when used with Argon-rich shielding gas mixtures, resulting in deep penetration and excellent sidewall fusion. Unlike traditional flux-cored wires, the MC-90 leaves minimal silicon islands rather than a heavy slag covering, significantly reducing inter-pass cleaning time and improving overall throughput in multi-pass operations. Its formulation is specifically balanced to minimize spatter, ensuring a clean workspace and reducing post-weld grinding requirements.

This 33lb spool is designed for continuous operation in semi-automatic and robotic welding cells. The .052-inch diameter allows for higher current carrying capacity, enabling faster travel speeds and increased deposition rates compared to smaller diameter wires. Whether utilized for crane manufacturing, earthmoving equipment repair, or critical structural components, the Metalshield MC-90 ensures weld integrity and consistency. It meets AWS E90C-K3 classifications, certifying its capability to perform under stress while maintaining ductility and impact toughness.

Industrial Applications

The Metalshield MC-90 is particularly suited for industries where weld failure is not an option. Its ability to handle contaminants better than solid wire, while maintaining high travel speeds, makes it a versatile solution for shops processing large volumes of high-strength steel. By integrating this wire into your welding procedure, you ensure compliance with stringent engineering specifications while maximizing operational efficiency.
