Value Collection 21578 Rosin Core Solder

Product Description

The VALUE COLLECTION 21578 is a rosin core solder formulated with a lead, tin, and antimony alloy. Rosin core solders carry flux inside the solder wire itself, eliminating the need for separate flux application during most electrical and light mechanical soldering tasks. This solder type is commonly used by electricians, HVAC technicians, and plumbers when making reliable, low-resistance joints on copper and brass components. The rosin flux core activates during heating to clean oxide from metal surfaces, promoting strong solder adhesion. It is suited for use with a standard soldering iron or soldering gun in bench or field applications.

This solder is appropriate for electrical connections, light copper plumbing joints, and HVAC control wiring repairs where a rosin-based flux is acceptable. It is well matched to residential and light commercial service work. Technicians working on control boards, transformer terminals, sensor leads, or low-voltage wiring will find this alloy composition suitable for standard soldering operations. It is not formulated for high-temperature or structural applications.

Key Features

• Rosin core design integrates flux directly into the solder wire for single-step application
• Lead, tin, and antimony alloy composition supports strong, clean solder joints
• Compatible with standard soldering irons and guns used in trade service work
• Suitable for electrical, low-voltage, and light copper soldering tasks
• Sold as an individual unit with no minimum quantity beyond one

Compatibility

Designed for general-purpose rosin core soldering applications in electrical, HVAC, and plumbing service work where lead-based rosin core solder is appropriate for the task.

Installation Notes

Soldering work on energized electrical systems must be performed only after power has been isolated and locked out per applicable NEC guidelines. Allow the soldering iron to reach full operating temperature before applying solder to ensure proper flux activation and joint formation. Work in a well-ventilated area when using lead-bearing solder, as fumes from flux and molten alloy can be hazardous. Dispose of lead-containing solder scraps in accordance with local regulations.
