In an industrial context, Solder Bar is hugely used in the electronic and electrical industry. which may be of the metal itself or alloy of metals at very low temperature. On the basis of usage and percentage of components, There are two types of solder wire called Lead-Free Solder Bar and Leaded Solder Bar. Some times we call them as Soft solder Bar and Hard Solder Bar. The melting point of soft solder Bar is low and for Hard solder Bar, the melting point is high. Now if we talk about Leaded Solder. Leaded solders contains different composition of Tin and Lead. Containing lead make them toxic. They melt at around 183°C, and it is popular due to its low cost. Lead-free solder Bar contains different composition of Tin, Silver and Copper.Because they fulfill the ROHS rules so they are allowed to use in various applications.
At Yunfang metals, several compositions are available Like in Lead-free solder Bar we have Sn99.3Cu0.7, Sn99Ag0.3cu0.7, Sn96.5Ag3.0Cu0.5, Sn95Sb5, Sn42Bi58 and in Leaded Solder wire we have Sn63Pb37, Sn60Pb40, Sn55Pb45. Some of The feature which our products contain. Good wettability and expandability, effectively preventing bridging, tripping, etc. forming an anti-oxidation film on the surface of the solder joint after soldering, slowing the oxidation of the solder joint and keeping the solder joint bright.
