Solder bar Tin flat bar has obvious different metal characteristics from traditional tin alloy, and it is the alloy component with the most perfect metal properties in lead-free tin strip. Sn96.5ag3.0cu0.5 is a high melting point lead free alloy, tin silver copper is the standard in the electronics industry, Better thermal cycle fatigue resistance, better surface tension, bright surface gloss, high purity, good fluidity after melting, superior thermal cycle, good infiltration and weldability, less oxide residue generation, has been widely used in all kinds of high-end requirements of wave soldering products and electroplating process.
