alloy composition: tin (Sn): 99.95%
weight: 0.7-0.85kg/strip
melting point: 217℃-221℃
application scope: manual soldering, wave soldering
Performance: Lead-free solder bars are made of high-purity metal raw materials. Under strict quality control, the content of metal oxides and non-metal impurities are effectively controlled. The produced solder bars have a uniform and smooth surface, high purity, fast melting, and good fluidity. , Excellent wetting performance, full and bright solder joints, and very little oxidized slag. Suitable for all kinds of wave soldering and manual soldering with high quality requirements. Our company continues to research and develop, and can provide a variety of alloy ratios, and multiple types of lead-free tin bars for you to choose from. (Shape: casting bar, extruded bar)

performance:
Due to the relatively low cost of tin-lead solder bars, our company advocates the most cost-effective concept and produces tin-lead solder bars with various alloy compositions and functions. We have electrolytic solder bars, high-temperature tin bars and all-in-one series of tin-lead solder bars. In particular, 63/37 solder bars have various advantages that lead-free solder bars cannot match, and they are recognized as the best tin-lead solder. It is loved by the electronics industry for its good soldering performance. It is widely used in automatic wave soldering and manual soldering operations. The 63/37 solder bars produced by our company have the advantages of good fluidity, wettability, and solder joints. Bright; excellent antioxidant, low tin dross; the addition of additives can change the crystal structure of solder joints, reduce internal stress, and resist the growth of whiskers; excellent joint performance, very few sharpening and bridging; solder joint machinery Good performance.
