MULTICOMP 812040 Solder Wire

The 812040 is a 0.5mm lead-free solder wire made from an SN-CU alloy with a 99.7/0.7 grade. It features a halide-free formulation based on modified rosin flux and carefully selected activators. The flux in this solder wire produces a mild rosin smell and leaves a small amount of clear residue, allowing for repair operations after cleaning without the need for further cleaning. It provides fast soldering on copper, brass, and solder-coated materials, with good activity on nickel surfaces depending on oxidation. The product is heat stable, exhibits low spitting, and is suitable for maintenance and repair applications.
