PureFusion Ultra-Low "IR" Solder 15g

Raise the Standard of Your Soldering Game

Designed for serious builders, racers, and electronics professionals, PUREFUSION™ SOLDER brings elite conductivity and ultra-clean flow to every joint. Crafted with a high-purity Sn99.3Cu0.7 alloy, this lead-free wire delivers low resistance, high strength, and a consistent melt point—perfect for high-performance RC applications, wiring, and electronics assembly.

Disclaimer: This solder is lead-free  which naturally cause the solder to have a dull finish and requires the use of flux for best results. Please note that joints may appear with a duller finish compared to traditional leaded solder — this is normal and does not affect performance.
