1 / 7HTM 60/40 Rosin-Core Solder Wire, 0.8 mm, 50 g
Kaisi: HTM 60/40 Rosin-Core Solder Wire is a 0.8 mm, 50 g tin-lead solder wire intended for electronics soldering. Its listing specifies a rosin core and 1.8% flux, making this a compact spool for circuit-board work where a relatively fine wire is useful.
At a glance
- Fine 0.8 mm wire is listed for controlled solder application on circuit boards and small projects.
- The listing identifies a Sn60-Pb40 alloy with a rosin core and 1.8% flux content.
- The stated 183°C melting point may suit work where a lower melting point is preferred, subject to the task and equipment.

Pros and cons
Pros
- A 50 g spool is a compact quantity for occasional electronics repairs or small projects.
- Rosin-core wire has flux built in, so separate flux is not necessarily needed for every joint.
Cons
- This is lead-based solder, which may not suit lead-free requirements or every workplace and application.

What to know before buying
Listing details to confirm
The title and detailed specifications consistently describe HTM 60/40 solder, but the product-information brand field says Kaisi while the listing names HTM and HengTianMei elsewhere. The title and feature copy state 183°C, while the detailed specification gives 361°F/183°C. Verify the brand and temperature details in the selected listing. The listing warns that the product contains lead and advises washing hands after use. It also says it is not recommended for water supply systems.
