(0.8mm,100g) Lead-free Solder Wire Flux-core Solder Welding Wire Electronical Soldering with Rosin Core,Sn99 Cu0.7 Ag0.3

Lead Free Solder Wires are soldering materials for engineering, and electronic repairs. Lead-free tin-silver-copper alloy for simple applications. Tin-Silver-Copper (Sn-Ag-Cu, or "SAC") solders based on the reduced melting point of the Sn-Ag-Cu ternary eutectic behavior (217 C), which is below the 22/78 Sn-Ag (wt.%) eutectic of 221 C and the 59/41 Sn-Cu eutectic of 227 C Rosin Flux Rosin flux , used in electronics, where the corrosiveness of the vapors released when acid flux is heated would risk damaging delicate circuitry. Flux is a reducing agent designed to help reduce metal oxides at the points of contact to improve the electrical connection and mechanical strength Tin / Silver / Copper: 99% / 0.3% / 0.7%; Lead free Flux: 2% Weight: 100g (0.22lb) Diameter: 0.8 mm Melting point:215 C - 220 C (419F - 428F) Package Included 1 Spool Solder Wire
