Sn70Pb30 Tin Lead Solder Wire
Sn70Pb30
Tin Lead Solder Wire
Sn70Pb30 tin lead solder wire is a tin-rich leaded solder alloy designed for electronic soldering, repair, and general assembly applications. With a melting point of approximately 195°C and available diameter from 0.38mm, it provides good solderability, smooth flow, and reliable joint formation for conventional tin-lead soldering processes.
A tin-rich leaded solder wire for smooth soldering.
Sn70Pb30 solder wire contains a higher tin ratio than standard Sn60Pb40 or Sn63Pb37 solder wire. It offers good wetting behavior, clean solder joint appearance, and stable soldering performance. This alloy is suitable for manual soldering, PCB repair, electronic maintenance, and applications requiring a tin-lead solder wire with good flow characteristics.
Tin-Rich Alloy
Higher tin content supports good wetting and smooth solder flow.
Good Solderability
Suitable for common tin-lead electronic soldering processes.
Reliable Joint Formation
Helps form clean and stable solder joints during repair and assembly.
Flexible Supply
Available in multiple wire diameters, flux types, and packaging formats.
