The VALUE COLLECTION 21561 is a rosin core solder made from a 60/40 tin-lead alloy, designed for electrical and electronic soldering applications. The rosin flux core activates during the soldering process to clean oxide from metal surfaces and promote a strong, conductive bond without requiring separate flux application. This solder is a standard choice for electricians, HVAC technicians, and electronics technicians working on circuit boards, wire terminations, and component-level repairs where a reliable tin-lead joint is required.
This 60/40 rosin core solder is suited for general electrical work including control board repair, terminal connections, and low-voltage wiring. It is commonly used in residential and light commercial HVAC control systems, electrical panels, and electronics servicing environments. The 60/40 alloy ratio provides a relatively low melting point and good flow characteristics, making it appropriate for hand soldering with a standard soldering iron or station.
Designed as a general-purpose rosin core solder for electrical and electronic soldering applications where a 60/40 tin-lead alloy is specified.
This solder is typically applied by a licensed electrician, HVAC technician, or electronics technician using a temperature-controlled soldering iron. Disconnect and de-energize any circuit or component before soldering. Work in a well-ventilated area, as the rosin flux produces fumes during the soldering process. Follow applicable NEC guidelines and local codes for any electrical repair or rework involving energized circuits.
