4000 Aluminium Alloy is a popular choice in MIG welding and brazing due to its excellent performance with heat-treatable metals. It's especially effective for welding aluminium alloys from the 6000 series and repairing aluminium-silicon cast alloys like grades 353 and A356. Its reduced sensitivity to weld cracking and ability to produce bright, smut-free welds make it a reliable option in industrial applications.
4043 series aluminium alloys primarily consist of aluminium and silicon, with the following typical chemical composition: (Al): 93.0% to 94.0%, (Si): 4.50-6.0%, (Mn): Maximum 0.15%, (Cu): Maximum 0.30%, (Fe): Maximum 0.60%, (Zn): Maximum 0.10%, and Residuals: Maximum 0.20%.
