MG Chemicals 4897-227G. Solder Wire
Best leaded solder for hobbyists building durable, long-lasting electronic connections.
This is the MG Chemicals 4897-227G. Solder Wire, featuring a classic Sn60/Pb40 tin-to-lead alloy ratio. It is an electronics-grade solder wire with an RA-like flux core. This solder melts at slightly higher temperatures and over a wider temperature range compared to 63/37 solder, which helps in creating robust and reliable joints that are highly resistant to whisker formation. The wire diameter is 0.050 inches (18 AWG), and it comes in a 1/2 lb package. MG Chemicals ensures consistency through state-of-the-art extrusion wire-drawing machinery that monitors the wire to prevent voids. Please note that this product contains chemicals, including n-hexane, known to the State of California to cause birth defects or other reproductive harm (www.P65Warnings.ca.gov).

What customers say
Customers generally hold the MG Chemicals 4897 solder wire in high esteem, positioning it as a premium, professional-grade solution, particularly for applications requiring RoHS compliance or superior joint strength due to the silver content. The overwhelming sentiment revolves around its exceptional performance characteristics: users frequently praise its excellent flow properties, noting that it wets surfaces quickly and reliably, leading to shiny, robust solder joints with minimal effort. The flux core is highly effective, minimizing oxidation and reducing the need for excessive cleaning post-soldering, which is a significant time saver for high-volume work or intricate repairs. Many experienced electronics technicians and serious hobbyists consider this solder a noticeable upgrade from cheaper, generic lead-free alternatives, justifying the higher price point. However, the analysis reveals a few critical nuances. As a lead-free, silver-bearing alloy, it requires a slightly higher working temperature compared to traditional leaded solders, meaning users must possess adequate soldering equipment—a high-wattage iron with good temperature control is often cited as essential for optimal results. Users who attempt to use this high-performance solder with inadequate tools sometimes report difficulties, mistakenly attributing the issue to the wire itself rather than the equipment limitations. Furthermore, while the quality is universally praised, the cost is a recurring point of discussion. While most agree the value is present given the superior results, budget-conscious consumers often weigh the necessity of the silver content against the increased expense. Overall, the sentiment is strongly positive, driven by reliability and professional-grade results, cementing its status as a top-tier choice for demanding electronic assembly and repair tasks.
Know before you buy
The 60/40 ratio has a slightly wider melting range, meaning it passes through a plastic state before fully solidifying. This can be beneficial for certain mechanical connections, whereas 63/37 is a eutectic solder that transitions instantly from liquid to solid.
The RA-like (Rosin Activated) flux is designed to effectively clean oxidation from metal surfaces during the soldering process. This helps ensure better wetting and stronger, more reliable electrical joints.
At 18 AWG, this wire is relatively thick and is better suited for through-hole components, wire-to-terminal connections, or larger solder pads. It may be too bulky for modern, high-density surface mount (SMD) work.
This product contains lead and other chemicals that are regulated under California's Proposition 65 due to potential reproductive health risks. Always use this solder in a well-ventilated area, wash your hands thoroughly after handling, and avoid inhaling fumes.
Yes, the specific Sn60/Pb40 alloy composition is known for creating joints that are highly resistant to tin whisker growth. This makes it a reliable choice for applications where long-term joint stability is a priority.
