Unlike other similar products, these aluminum welding rods offer excellent welding performance with a low melting point, corrosion resistance, high thermal conductivity, and high electrical conductivity. Suitable for welding various metals including stainless steel, iron, aluminum, and copper pipes, as well as electronic components and electrical circuits. The rods feature an aluminum alloy core with a salt-based coating, eliminating the need for additional flux powders. No other materials are required, making them easy to use. Ideal for use in power, chemical, food, and aluminum electrolysis industries. Provides quick and efficient welding for both household and industrial applications. These versatile welding rods are perfect for repairing water pipes, gas pipes, stainless steel pipes, iron pipes, copper pipes, aluminum pipes, water tanks, electronic components, and electrical circuits. The internal powder ensures strong weldability and corrosion resistance, while the copper-aluminum construction delivers high thermal and electrical conductivity. Offers excellent workability with a smooth and consistent weld bead. Suitable for argon arc welding and as filler material for pure aluminum. Durable, odor-free, and rust-resistant, these welding rods are a reliable choice for a wide range of welding tasks.
