Tin Lead Solder Wire Sn50Pb50 50 50


Tin Lead Solder Wire Sn50Pb50 50 50

Solder Wire 50 50

Tin Lead Solder Wire 50 50, scientifically known as Solder Wire Sn50Pb50, is a soldering material comprised of an equal composition of 50% tin (Sn) and 50% lead (Pb). This solder wire strikes a harmonious balance between tin and lead, making it a versatile choice for various soldering applications such as electronics assembly and metal joinery. It's produced into wire form and winded into rolls, making it very convenient for soldering.

Features of Tin Lead Solder Wire Sn50Pb50 50 50:

Equilibrium Composition

The   50 50 ratio ensures a stable and consistent soldering performance, yielding uniform results.


Satisfactory Properties

Sn50Pb50 solder wire has good mechanical strength and wetting property, which ensures strong and reliable solder joints.

Good Fluidity

The rosin flux core helps the solder flows smoothly and evenly, preventing cold joints and voids in the solder joint.



Solder wire 50 50 has lower percentage of tin when comparing to solder wire 63/37,  that reduces its cost, making it a popular choice in both industrial and hobbyist soldering applications.


Applications of Tin Lead Solder Wire Sn50Pb50 50 50:

Soldering electronic components to printed circuit boards (PCBs) or wires.


Soldering copper pipes in plumbing systems.


Soldering jewelry and decorative items.


Soldering musical instruments such as brass and woodwind instruments.


Soldering stained glass create intricate connections in stained glass projects.

How to use Tin Lead Solder Wire Sn50Pb50 50 50?

For manufacturing of electronics assembly, the soldering can be done manually by using soldering irons or soldering stations.


For soldering stained glass, generally we recommend to use solid wire and apply the flux in separate. The soldering is carried out by electrical soldering irons too.


For soldering copper plumbing systems, we also recommend to use solid wire and apply compatible external flux. The soldering is carried out by using torch gun.


Precaution for using Tin Lead Solder Wire Sn50Pb50 50 50:

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.
