II. Core Product Advantages
1. Welding Performance Advantages
Easy Arc Striking & Low Spatter: The wire surface undergoes special treatment, with an arc striking success rate of over 99%. The spatter during welding is 30% less than that of ordinary aluminum welding wires, reducing subsequent weld cleaning work and improving operation efficiency.
Excellent Molten Pool Fluidity: The high-silicon composition design enables the molten pool to spread faster, which can quickly fill the weld gap. It is especially suitable for the dead-angle welding of complex structural parts, avoiding incomplete penetration defects.
Stable Weld Quality: After welding, the tensile strength of the weld can reach more than 170MPa, the elongation rate is ≥8%, and there is no obvious rust in the salt spray corrosion test (500 hours), meeting the durability requirements of welds in the automotive and shipbuilding fields.
Low-Temperature Welding Adaptability: The relatively low melting point can reduce the heat input of the base metal, avoiding deformation and burn-through of thin aluminum parts (thickness ＜1mm) during welding, and adapting to the processing of precision aluminum products.
