High-quality materials: Low-temperature universal welding rods are made of high-quality materials and feature high strength, good ductility, and good corrosion resistance. No welding powder required: Low temperature universal welding rods do not require additional flux powder, making them convenient and easy to use. Low Temperature Welding Rod: This electrode operates at low temperatures, suitable for welding applications requiring lower heat input. Easy to use: These welding rods offer excellent weldability and insulation, and can be welded directly with a lighter without a welding gun, ideal for both beginners and professionals. Wide Application: Suitable for various applications including circuit boards and electronic devices; compatible with copper, iron, aluminum, stainless steel, and other metals. Note: The material is relatively brittle and may break upon arrival. This is normal and does not affect performance. Notice: Actual color may vary slightly due to lighting effects. Allow 1-3 cm deviation due to manual measurement. Material: Aluminum powder Size: 10 x 4 x 1 cm
