E4047 aluminum electrode is aluminum-cored and flux coated stick electrodes for use only with DC welding machines in welding aluminum and its alloys. It is designed for welding aluminum-silicon castings and alloys with high silicon content (up to 12%).

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).

E1100 aluminum electrode is a pure aluminum electrode with a salt-based coating. Use DCEP (direct current electrode positive). Try to use a short arc to weld.

ENiFe-C1 is a cast iron electrode with a nickel-iron alloy core and a strong reducing graphite flux. It features high strength, good ductility, and a low coefficient of linear expansion.

Suitable for welding gray and ductile iron at room temperature or with minimal preheating (up to ~200°C). Works with AC/DC power. Ideal for repairing high-strength gray and ductile iron castings, such as cylinders, engine blocks, gears, and rolling mills.
