Tin Lead Solder Wire Sn40Pb60 40 60


Tin Lead Solder Wire Sn40Pb60 40 60

Solder Wire 40 60

Tin Lead Solder Wire 40 60, scientifically known as Solder Wire Sn40Pb60, is a soldering materialcomposed of 40% tin (Sn) and 60% lead (Pb). Solder Wire 40 60 is meticulously formulated by blending specific proportions of tin and lead, chosen for their complementary properties that contribute to effective soldering. As the results of good solderability with its affordable cost, it has been widely in many applications.

Features of Tin Lead Solder Wire Sn40Pb60 40 60:

Medium Melting Point

The solder wire 40/60 has a higher melting point than solder wire 63/37, making it suitable for components or devices that requires a bit higher working temperature.

Easy to Use

Solder Wire 40 60 contains a rosin flux core, that means it can be used directly for soldering and no need to add any external flux.

Good Performance

The solder wire Sn40Pb60 has good wetting and flowing property, it can form a round, smooth and form solder joints.

Cost Effective

The cost solder wire 40 60 is much lower than solder wire 63/37 or lead free solders, it can cut down the manufacturing cost.


Applications of Tin Lead Solder Wire Sn40Pb60 40 60:

Electronics and electrical devices production: that is mainly for assembly for all types of PCB and joinery for different IC components together. Such as home appliances, wearable electronics devices, electrical parts etc.


General soldering purpose: That is for some repairing work of electronics or electrical products, and some small projects of lobbyists.


Plumbing system: it's used to join the copper pipes and copper fittings for the plumbing systems.


Radiators: it's used for assembling the copper and brass radiator end plates.


Stained Glass: it's used for soldering of the lead came of the stained glass for create shapes and looks.

How to use Tin Lead Solder Wire Sn40Pb60 40 60?

When using solder wire 40 60 for electronics assembly, we recommend to use the rosin flux core type. It's a handy formula that contains flux inside the wire, and there is no need to apply external flux when doing the soldering task. We will need soldering irons or soldering stations to carry out the soldering process.


When suing solder wire Sn40Pb60 for plumbing systems or radiators assembly, we recommend to use the solid wire without flux core, and then prepare compatible strong flux in separate for the soldering. And we will need torch gun to do this soldering process.


Precaution for using Tin Lead Solder Wire Sn40Pb60 40 60:

Use in a Well-Ventilated Area: Always solder in a well-ventilated space, such as a fume hood or near an open window, and use exhausting fan. Proper ventilation helps to dissipate harmful fumes and reduce the risk of inhaling lead vapors.


Wear Personal Protective Equipment (PPE): Consider wearing appropriate personal protective equipment, including safety glasses, gloves, and a lab coat or apron, to minimize skin and eye contact with solder and flux.


Avoid Ingestion and Hand-to-Mouth Contact: Never eat, drink, or smoke while working with leaded solder. Wash your hands thoroughly after handling solder and before eating or touching your face.
