Introduction in details for Sn40Pb60 core wire
Sn-Pb60older wire is the most common type of tin-lead alloy solder, which features the maximum dosage and demand. 40/60 tin lead welding wire represents that the alloy contain 40% tin content and 60% lead content in the solder, the diameter of Sn40Pb60 solder wire is from 0.35mm to 6.0mm. It is mid temperature solder wire which its melting point is 225degree Celsius.
Sn40Pb60 no clean flux core solder wire can offer quite stable welding performance.
Export range
So far,our Sn40Pb60 core solder wire have been exported to Mid-East countries, Australia etc.

4. How to chose solder

   Select the solder composition. First choose between leaded or lead free and then between high or low temperature. Choose high temperature for easily accessible connections and low temperature for smaller, crowded connections. Next choose the alloy. Leaded solder ranges from 40 percent tin and 60 percent lead (40/60) to 50/50, 60/40 and 63/37. The first number always represents the tin content; the higher the tin content, the lower the melting point. The most common lead-free solder contains 95 percent tin and 5 percent antimony but has a melting point between that of 40/60 and 50/50 tin/lead solder. Only experience will direct you in making exact choices for your application

Range of application:
Soldering in TV set, radio or normal home appliances. Repair of normal home appliances and audio facilities.Soldering in radio transponder, instrument and calculator and so on.
