Tin spool of 250g Sn60Pb38Cu2 flux 2.2% High quality trimetal tin, ideal for manual or robotic soldering electronic applications where it is necessary to incorporate a resin core into the wire. The core with resin has the function of stripper, responsible for deoxidizing metals, reducing surface tension and improving heat transfer. This ensures: - good filling - Durability - Higher productivity - Reduction of voids - No bad odors - Greater fluidity Characteristics: - Weight: 250g - Wire diameter: 1mm - Composition Tin 60% / Lead 38%/Cu 2% (Sn60Pb38Cu2) - Flux 2.2% REL0 - Melting point 183-190ºC - Density 8.87g/cm3 - Reel measurements: 56.5mm high, 49.5mm diameter Spanish Manufacture
