Key Features
- Ideal 1.0mm Diameter: A versatile wire thickness suited for a broad range of household soldering tasks — from circuit board touch-ups to metal joining and small hardware fixes.
- Multiple Weight Options: Choose from 20g, 50g, or 100g rolls so you always have the right amount on hand — whether it's an occasional repair or a frequent DIY project.
- Built-in Rosin Flux Core (2.2%): The integrated rosin flux prevents metal surface oxidation during soldering, promotes even solder flow, and produces clean, smooth joints — no separate flux needed.
- Low Melting Point (~200°C): The high-purity tin-lead alloy formula melts at a low temperature, making it compatible with common heating tools for simple everyday soldering work.
- Wide Metal Compatibility: Works effectively on stainless steel, carbon steel, and most standard household metals, forming tight, durable bonds after cooling.
- Neatly Wound Spool: The wire is wound cleanly and evenly to prevent tangling. Compact and lightweight enough to fit in a toolbox, drawer, or repair kit.

Frequently Asked Questions
Q: What metals is this 1.0mm solder wire compatible with?
A: This rosin core solder wire works well with stainless steel, carbon steel, and most common household metals. The tin-lead alloy bonds tightly to metal surfaces, creating solid, durable connections after cooling.
Q: Do I need separate flux when using this soldering wire?
A: No — the solder wire has a built-in 2.2% rosin flux core. This means you can solder directly without applying external flux, saving time and ensuring cleaner, more consistent joints.
Q: What heating tools are needed to melt this solder wire?
A: Thanks to its low melting point of approximately 200°C, this solder wire is compatible with standard soldering irons and common heating tools suitable for small repairs. A professional welding machine is not required for everyday tasks.
Q: Which spool weight should I choose — 20g, 50g, or 100g?
A: The 20g spool is ideal for occasional repairs and light use. The 50g option suits regular hobbyists, while the 100g spool is best for frequent DIY projects or keeping a larger supply on hand in your workshop.
