Introduction
The fabrication of modern railway cars requires filler metals that offer a combination of high tensile strength, fatigue resistance, and smooth weld bead aesthetics. Our dedicated wire formulations, including specific high-Magnesium alloys, are engineered to meet the stringent safety and longevity standards of the rail industry. These wires ensure consistent mechanical properties across complex, long-run welds typical in train carriage assembly, contributing to reduced weight and increased energy efficiency in transportation systems.
