Product Description
ER4043 aluminum welding wire is an aluminum-silicon alloy welding wire.
Main ingredients and characteristics
Main ingredients: ER4043 aluminum welding wire contains about 5% silicon, the rest is aluminum and a small amount of other elements (such as Mg≤0.10%, Fe≤0.04%, Cu≤0.05%).
Characteristics:
Good fluidity: Due to the right amount of silicon, the welding wire has good fluidity during welding, which is convenient for filling the weld.
Strong resistance to thermal cracking: ER4043 aluminum welding wire has strong resistance to thermal cracking, which can effectively avoid cracks during welding.
Certain mechanical properties: Although the ductility is relatively insufficient, it can still guarantee certain mechanical properties.
