4043 Aluminium TIG Rods / Wire

4043 aluminium TIG rods are a general-purpose filler alloy that is commonly used for welding aluminium. They are made with 5% silicon, which gives them excellent fluidity and weldability. 4043 rods are also known for their good corrosion resistance, making them a good choice for applications where this is a critical factor.

4043 rods can be used to weld a wide variety of aluminum alloys, including 3003, 3004, 5052, 6061, and 6063. They are also suitable for welding cast aluminum alloys such as 443, 355, 356, and 214.

If you are looking for a general-purpose aluminium filler alloy that is easy to weld and provides good corrosion resistance, then 4043 rods are a good option.
