Premium Lead-Free Solder Wire – Perfect for Your Precision Soldering Needs

Experience top-tier performance with this Lead-Free Solder Wire. Certified with RoHS compliance, this soldering wire is both environmentally friendly and safe for use in a variety of applications.

Key Features

High-Quality Composition: Composed of 99.7% Tin (Sn) and 0.3% Copper (Cu), which ensures excellent conductivity and reliability.

Effortless Soldering: The 2% Rosin Flux Core simplifies the soldering process, providing smooth and efficient flow for clean and strong joints.

Convenient Weights: Choose from 50g or 100g rolls to match the scale of your projects.

Versatile size: 0.8 mm diameter is considered the optimum size for precision soldering and also for use where larger welds are needed.

Enhanced Performance: The effective rosin flux core actively cleans the surface during soldering, minimizing spatter, smoke, and odor for a relaxed working environment.

Superior Solderability: Enjoy excellent insulation resistance, non-corrosive properties, and consistent, high-quality results with minimal spattering.

Elevate your soldering experience with our premium lead-free solder wire – the perfect blend of quality, safety, and performance!

What's Included?

One roll of solder wire weighing either 50g or 100g, depending on the option you selected. In rare cases, we may ship two 50g rolls instead of a single 100g roll if the latter is temporarily out of stock—though this is unlikely, as we regularly restock both sizes. Please note that packaging and labelling may vary, but the quality, composition, and purity of the solder wire remain consistent. Weights include the roll (which represents less than 5% of the total weight).

Frequently Asked Questions (FAQ)

What is rosin core solder wire?

Rosin core solder wire contains a flux core made from natural rosin. This flux helps clean metal surfaces during soldering, ensuring a strong, reliable joint.

Why is flux important in solder wire?

Flux removes oxidation from metal surfaces, improves solder flow, and prevents defects like cold joints or poor adhesion.

Is this solder lead-free?

Yes. Lead-free solder is safer for health and the environment but requires slightly higher soldering temperatures—all soldering irons are capable of working with lead-free solder.

Can I use rosin core solder for electronics?

Yes, rosin core solder is the standard choice for electronics work because it provides effective flux action without damaging sensitive components.

Is rosin core solder safe to use?

Yes, but it should be used in a well-ventilated area to avoid inhaling fumes (using a fan is recommended). Always follow safety guidelines detailed in your electronics kits instruction manuals and wash hands after handling.

Can rosin core solder be used on all metals?

Rosin core solder works best on copper, tin, and other common electronic metals but is not suitable for plumbing or high-temperature metals like stainless steel.

Does rosin core solder require cleaning after soldering?

Typically, no cleaning is necessary because rosin flux residue is non-corrosive. However, for sensitive or high-reliability circuits, cleaning may be recommended. Cleaning can be done using a soft brush dipped in 70% IPA or specific products such as Chemtronics Flux-Off. Ensure all surfaces/components are fully dry again after cleaning.

Good value

Good solder, low splatter and low smoke. Gives a nice clean shiny joint. Have experimented with temperatures, I found 380ºC works best with this.

Hello Ronnie, thank you for taking the time to leave this review, we really appreciate it. The optimal temperature you've determined for this solder wire is almost exactly what is recommended by the manufacturer (378ºC), so well done on such precise experimentation!

Flows really well

Perfect for soldering a wide variety of components, from through-hole to SMD. No spattering and low smoke. Very good value for money. Will have this on regular order.

Hello, thanks for taking the time to leave this review - happy to hear the solder is performing well for you and that it meets your needs for both through-hole components and surface mounted devices. I note you ordered the 50g roll last time - the 100g roll is approx. 25% cheaper!
