TOWOT Sn63 Pb37 Solder Wire 1.0mm 50g
TOWOT 63-37 solder wire is a rosin-core alloy with 63% tin and 37% lead, supplied on a 50 g spool at 1.0 mm diameter. The 1.8% flux content promotes fast wetting and strong joints for electrical soldering tasks. It is aimed at hobbyists, technicians and repairers working on circuit boards and general electronics.
Suits through-hole work and larger SMD pads.
The 1.0 mm diameter feeds well for through-hole components, connectors and larger surface-mount pads. It is less suited to very fine-pitch ICs or dense boards where a thinner wire would give better control. Users who need lead-free alloys for regulatory compliance should select a different product.
Alloy fixed at Sn63 Pb37 with 1.8% rosin flux
The tin-lead ratio and flux percentage are set by the manufacturer and cannot be changed. This composition determines melting behaviour, joint strength and residue characteristics for every application. Verify that Sn63 Pb37 meets your project or industry requirements before purchasing.

Questions about this item
What diameter soldering iron tip works with the 1.0mm wire?
A tip that accepts 1.0mm diameter wire is required; the product notes compatibility with H-1050 equipment.
How do I avoid cold joints when using the 63/37 alloy?
Heat both pad and lead until the 1.8% rosin flux activates and the solder flows smoothly before removing the iron.
When will I need to replace the 50g spool?
Replace it once the 50g of Sn63 Pb37 alloy is consumed; the rosin core depletes with the wire.
