Specification: Model: ER4043 Diameter: 0.035" (0.9 mm) Roll Weight: 1 Lb Quantity: 6 Rolls Material: Aluminum Description: Aluminum 4043 Mig Welding Wire 6 Rolls ER4043-.035" 1Lb Roll The Aluminum 4043 MIG welding wire provides high reliability and consistent performance, making it an ideal choice for various welding tasks. It possesses good heat resistance, ensuring stability and strength in the welded joints. The ER4043, also known as AlSi5, is a filler metal containing 5% silicon, which enhances the weld quality by reducing the risk of cracking. .

Specification: Model: ER4043 Diameter: 0.035" (0.9mm) Roll Weight: 1 Lb Quantity: 6 Rolls Material: Aluminum Description: ER4043, commonly referred to as “AlSi5", has a 5% silicon and is the oldest and one of the most widely used aluminum welding wires for general purpose applications. Less sensitive to weld cracking than other aluminum alloys and the 5% silicon content lowers the melting point, increases fluidity of the weld puddle and leaves a bright shiny weld deposit. ER4043 is commonly used for welding grades 6061, 6063, 5052, 3004, 3003 and cast alloys 356.0, 357.0, 413.0, and 443.0 to name just a few. .
