描述： The 509-0519 is a 0.5mm 60/40 grade Flux Cored Solder Wire, made of Sn and Pb alloy. This contains a careful balance of resins and activators to provide clear residues, maximum activity and high residue, reliability, without cleaning in most situations. Good results should be obtained using a range of tip temperatures. However, the optimum tip temperature and heat capacity required for a hand soldering process is a function of both soldering iron design and the nature of the task and care should be exercised to avoid unnecessarily high tip temperatures for excessive times. A high tip temperature will increase any tendency to flux spitting and it may produce some residue darkening. It provides fast soldering on copper and brass surface as well as solder coated materials. Activity of the halide activated versions on nickel is also good depending on the state of oxidation of the nickel finish. . Rosin based . Fast soldering . Pale residues . Solders difficult surfaces . Heat stable, low spitting
