ER4043 WELDING WIRE OVERVIEW: This 5% silicon aluminum (AlSi5) filler metal welding wire is designed for the MIG welding process. It has a melting range of 1065°F to 1170°F, a density of 0.097 lbs/in³, and produces a gray color after anodizing.
SUPERIOR PERFORMANCE: The addition of silicon enhances fluidity (wetting action), making this alloy a preferred choice among welders. It is less sensitive to weld cracking and produces a brighter finish.
VERSATILE APPLICATIONS: Ideal for welding various grades of aluminum, including 3003, 3004, 5052, 6061, 6063, as well as casing alloys 43, 355, 356, and 214.
DURABLE SPOOL DESIGN: Constructed from new ABS plastic, this spool is durable, tough, and resistant to damage. It not only protects the wire during transportation but also ensures smooth operation within the machine.
