E4043 aluminum electrode is a type of aluminum stick welding electrode. It is made from a silicon-based aluminum alloy and coated with salt-base flux. It features a stable arc, low spatter, good weldability and high resistance to thermal cracking, making it one of the most widely used aluminum electrodes. Applications: Ideal for welding cast aluminum and 6000-series aluminum alloys (e.g., 6061, 6063).
