Autocraft AL4043 is a premium quality Aluminium - nominal 5% Silicon alloy suitable for the Gas Metal Arc Welding (GMAW) of a wide range of cast and wrought Aluminium alloys. Autocraft AL4043 is used extensively for the repair welding of many aluminium alloy castings. Its lower weld deposit strength, and excellent crack resistance make it suitable for the GMA welding of cast ( mainly 4XX & 6XX series ) and wrought ( selected 1XXX, 5XXX & 6XXX series ) aluminium alloys, except where an accurate colour match is required after anodising. See CIGWELD Aluminium Alloy Selection Chart for detailed welding consumable selection criteria for a wide range of Aluminium alloy parent metals. P/N: 722237 Variations: 722238
