The 24-4060-2437 is a flux-cored solder wire designed for general-purpose soldering. This product features a 0.125-inch diameter wire composed of a 40% Tin and 60% Lead alloy. It contains a highly active inorganic acid flux core, which constitutes 3.3% of the total weight (Core Size 66), and is supplied on a 1-pound spool. The acid flux provides excellent thermal stability for high-temperature applications like torch soldering and is effective on oxidized metals. Due to the corrosive nature of the residue, it is not recommended for electrical or electronic soldering.
