Aluminum welding wire

AWS ER4145

TYPICAL APPLICATIONS

ER 4145 aluminum welding wire is a specialized alloy utilized for welding and brazing applications, particularly in the aerospace industry. Its chemical composition is significant due to the inclusion of 5% magnesium, which enhances strength and corrosion resistance, while the addition of silicon helps improve fluidity during the welding process, resulting in smoother, more precise welds.
