The Felder Lottechnik 18.600.52037 wire solder is a traditional, professional-grade lead-containing alloy with a composition of 60% Tin and 40% Lead. This specific formulation, designated as ISO-Core RA, is provided in a fine 0.5mm diameter wire form and contains a 2.5% rosin-based flux core, ensuring excellent flow characteristics and superior wetting for reliable electrical connections. Its low melting point of 183°C makes it ideal for precision soldering tasks in electronics and electrical work, delivered in a convenient 250g spool.
This lead solder (60Sn/40Pb) is prized for its low melting point (183°C), which minimises thermal stress on sensitive components. The rosin-based flux core ensures strong, shiny, and highly conductive solder joints with exceptional wetting properties. Its narrow 0.5mm diameter makes it perfect for precise, fine-pitch electronics and surface mount repair work.
