Standard Aluminum Welding Wire ER4043 TIG MIG Welding Wire 1.2mm 7KG

Product Description

ER4043 aluminum welding wire is an aluminum-silicon alloy welding wire, which is widely used for welding aluminum alloy materials, especially 6xxx series aluminum alloys. The following are its main features and applications:

1. Chemical composition
Aluminum (Al): Remainder

Silicon (Si): 4.5-6.0%

Other elements: trace impurities such as iron (Fe), copper (Cu), zinc (Zn), magnesium (Mg)

2. Characteristics
Flowability: High silicon content, good fluidity after melting, suitable for complex welds.

Crack resistance: Excellent resistance to thermal cracking, suitable for welding thermal crack sensitive materials.

Strength: The strength of the welded joint is moderate, suitable for general structural welding.

Corrosion resistance: Good corrosion resistance, but not as good as pure aluminum welding wire.
