  Our company manufacture binary syytem of Sn-Ag 、Sn-Cu、Sn-Zn、ternary system of Sn-Sb-Cu、Sn-Ag-Cu and quaternary sytstem of Sn-ln-Ag-Bi or various proportions of lead-free solder. Company can produce different proportion of soldering flux or adjust flux type and content according to the requirement of customer.
  Uses:widely be used in electron、 electricity 、aviation technology 、aircraft industry ; printed circult 、wave-soldering 、soft solder in coating metal、radiator dip soldering ,cable joint, leaf metal, lead pipe soldering ,cable wire ,heat exchanging metal solder,tank welding etc..
  Advantage:

  1. pure-tin as raw material ,good wettability ,good flowability,easy affixing tin
  2. welding spot smooth,full ,without hollow weld etc..
  3. add enough inoxidizable element for better antioxidant capacity.
  4. Pure-tin as raw material,little tin-slag,reduce unnecessary waste.
  5. Be suitable for wave-solder or hand dip furnace.

  Packing:

  • 20kg/barrel,wooden case or carton.
  • According to the requirement of customer.
