Product Detail


4043 filler rod is usually used as ALSil, and is commonly used as filler material for argon arc welding and oxygen-acetylene gas welding of aluminum alloy workpieces and castings other than aluminum-magnesium alloys, especially for heat-treated strengthened aluminum alloys that are prone to hot cracks. Good results. 
 
Standard for 4043 filler rod: GB/T110858-2008 AWS A5.1 ER4043 4043 aluminum filler rod performance characteristics of 4043 filler rod: 4043 is an aluminum filler metal containing 5% silicon. It is a versatile aluminum-silicon alloy welding wire. The weld metal has excellent thermal crack resistance and can also guarantee certain mechanical properties However, in the case of anodizing, the color of the weld metal is different from the base metal. Colleagues' welding of aluminum-magnesium-gold produces brittle Mg2Si in the weld, which reduces the plasticity and corrosion resistance of the joint. The melting point of 4043 filler rod is in the range of 1065-1170oC, the color after anodization is off-white, and the minimum tensile strength is 186MP. 
 
Usage of 4043 filler rod
Uses: Recommended for welding 3003, 3004, 5052, 6061, 6063 and casting metals 355, 356 and 214. Weld the following aluminum alloys-automobile aluminum water tanks, intercoolers, radiators, aluminum alloy passenger car windows, bicycle frames, aluminum parts repair.
