Features:
- Stainless steel solder wire with rosin core is a multi-metal universal welding material, specially designed for difficult-to-weld metals like stainless steel, galvanized iron, carbon steel and copper. With built-in rosin flux, it enables strong soldering without extra flux, widely used in electronic repair, appliance maintenance and metalworking.

Material & Craft:
- Lead-containing stainless steel alloy with moderate melting point and good fluidity; built-in high-activity rosin core to remove oxide layers and improve wettability; bright anti-oxidation surface for long-term storage.

Structure Design:
- Optional diameters: 0.8mm/1.0mm; weight options: 50g/100g; compact spool packaging for easy use.

Specification:
- Size: 5×5×2.9cm, weight: 0.1kg (net 100g), diameter: 0.8mm/1.0mm, material: lead-containing stainless steel solder alloy + rosin core, applicable metals: stainless steel, galvanized iron, carbon steel, copper, iron parts, etc.

Advantages:
Multi-metal compatibility (works on stainless steel, galvanized iron); no extra flux needed (built-in rosin core); low residue and reliable joints; easy to operate (fast melting, good fluidity); wide application scenarios.

Application:
Electronic repair (circuit boards, components), appliance maintenance (stainless steel shells, metal parts), metalworking (stainless steel pipes, iron products), DIY crafts (jewelry making, model assembly).

Operation Steps:
- Clean the surface to remove rust, oil and oxide layers;
- Place the solder wire on the soldering area;
- Heat with a soldering iron ( 60W recommended) until the solder melts and spreads evenly;
- Let it cool naturally to form a strong and reliable joint.
