The most widely used aluminum welding wires are SAL4043 and SAL5356.
 
SAL4043 is usually used as ALSil and is an aluminum filler metal containing 5/100% silicon. It can be recommended for welding 3003, 3004, 5052, 6061, 6063 and casting metals 355, 356 and 214. The melting point temperature range of ER4043 is 1065-1170oF, the color after anodization is off-white, and the low tensile strength is 186MP
 
Performance characteristics: It is a versatile aluminum-silicon alloy welding wire. The weld metal has excellent thermal crack resistance and can also ensure certain mechanical properties. However, in the case of anodizing, the color of the weld metal and the base metal Differently, at the same time, the welding of aluminum, magnesium and gold generates brittle Mg2Si in the weld, which reduces the plasticity and corrosion resistance of the joint.
 
Uses: commonly used as filler material for argon arc welding and oxygen-acetylene gas welding of aluminum alloy workpieces and castings other than aluminum-magnesium alloy, especially for heat treatment strengthened aluminum alloys that are prone to thermal cracks, and can obtain good results.


 
SAL5356 is usually used as ALMg5. It is an aluminum alloy filler metal containing 5/100% magnesium. It can be used for MIG or TIG welding. It has good resistance to seawater corrosion. It can generally be used in base metals 5050, 5052, and 5083. , 5356, 5454 and 5456 welding. Its color after anodization is white, the tensile strength is 290MP
 
Performance characteristics: This product is an alloy welding wire containing 5/100% magnesium. It is a general-purpose welding material with a wide range of applications. It is suitable for welding or surfacing welding of cast-forged aluminum alloy of 5/100% magnesium. Good forgeability and good corrosion resistance. This product can also provide good color matching for anodized welding
 
Uses: bicycles, aluminum scooters and other sports equipment, locomotive compartments, chemical pressure vessels, military production, shipbuilding, aviation and other industries
