 Silver solder wire together and Sn Cu lead-free solder wire are lead-free solder wire series products have passed the European ROHS certification, with characteristics of solder wire inherent. Silver solder and Sn Cu lead-free solder wire with different points is more, the following answer. A different metal composition containing silver: the solder wire is composed of tin silver copper alloy, and tin copper wire is composed of lead free tin tin and copper alloy, non silver metal components. Two, melting point: because of the metal alloy is different, so the melting point is different. The silver solder wire at the melting point of 217 degrees, and Sn Cu lead-free tin the wire at the melting point: 227 degrees. 10 degrees. Three different color brightness: gloss solder joint appearance color luster color effect of the solder joint. Because silver is the color of metal, not bright metal, so silver solder wire solder joint is not bright luster, a matte silver solder. The SN Cu lead-free tin silk luster showed a certain brightness, appearance more beautiful. This is also one of the advantages of the tin copper lead-free tin wire, solder joints but luster color does not represent the welding performance of solder joint itself. Four, the comprehensive performance of different high temperature lead-free tin by silver metal under the action of silver tin solder wire than copper lead-free tin wire firmly better, stronger, more solid solder joint. Secondly, the index is also very important in the conductive properties of the solder joints, lead-free solder bar silver is a highly conductive metal, so silver solder wire than the conductive copper tin lead-free tin wire so, the thermal conductivity is better. The performance of Sn Cu lead-free solder wire can not be surpassed. Five different cost: lead-free tin as antioxidant silver metal price is high, so the silver solder wire than tin copper lead-free tin wire cost is more expensive. This is the most large Sn Cu lead-free solder wire The higher the content of silver contained in the silver tin wire, the more expensive the lead-free tin strip in hand dip furnace
