Filler Metal, 4043, Display Pack: 1 lb; AWS Classification: ER4043; Material: Aluminum; Type: TIG GTAW; Diameter: 1/16 Inch; Length: 36 Inch; Color: Gray; Amperage: 60 to 80 A; Voltage: 15 V; Flow Rate: 20 CFH; Yield Strength: 18500 psi – ER4043 is a 5% Silicon aluminum filler metal that is one of the most widely used aluminum welding alloys for fabrication and general repair in the aluminum welding industry. The smooth running ER4043 is often preferred because of its reduced crack sensitivity over other aluminum welding wires. This aluminum alloy contains silicon additives, which result in improved fluidity wetting action of the weld pool.
