Tin-lead solder wire is a type of metal alloy that is used to join two pieces of metal together by melting the solder and then allowing it to solidify, creating a strong bond. The specific product you mentioned, Tin Lead Solder Wire Tube (15g, 60/40 Flux), is a small tube of solder that is commonly used in electronics repair and other small soldering tasks.

The solder is composed of 60% tin and 40% lead, this alloy has a low melting point and is easy to work with. Flux is a chemical that is added to solder to help it flow and bond better.

The flux in the 60/40 solder wire tube is Rosin flux, it is a mild flux that is commonly used in electronic soldering. Rosin flux helps to remove any oxidation from the surfaces being soldered, which improves the bonding strength of the solder.

The wire is 15g, which is a small quantity and can be used for small soldering jobs, such as wiring and repairs of electronic devices.

Soldering wire is essential to electronics! This solder wire tube set will allow you to create permanent and proper devices once you have your design ready or simply need to repair a broken device.
