Sn99.95 lead-free pure tin wire mainly contains 99.95% tin, 0.05% of other trace elements. 99.95% of environmental friendly pure tin ingot is used as raw material, without any chemical flux. No welding smoke will be generated during soldering of soldering iron. Solid core solder wire is mostly used in handicraft industry as packaging or for flame welding industry. Solid core tin wire must be welded in the state of fire welding, and in other states, it must be stained with rosin or flux to produce various specifications of solid core solder wire in standardization. Process execution standard: gb/t728-2010 character: silver white metal, pale yellow surface, soft quality, good ductility. The melting point is 232C, density is 7.298g/cm3, and it is non-toxic. It is used for LED patch and chip solid crystal which can withstand high temperature welding. It has good welding strength, high temperature reliability and high thermal conductivity. Main uses: it is used in the production of tinplate, tin based bearing alloy, tin lead solder, tin chemical products, etc. it has been widely used in food packaging, electronic industry and glass manufacturing
Performance characteristics of solid core tin wire:
1. welding is free of smoke and corrosion of soldering iron.
2. the tin wire has solid core structure, and there is no void vacancy in the middle of the core.
3. the wire core does not contain flux, so soldering iron is difficult, and it is mostly used in handicraft.
