Solder: What You Need to Know

Solder products, also referred to as soldering materials or bonding agents, are essential for creating strong, conductive joints in electrical, plumbing, and metalwork applications. This collection includes flux pens, solder wires, pastes, and kits in both lead-free and silver-safe formulas. Options range in size from 0.25 lb. spools to 1 lb. solid cores, with refillable pens and tip-safe pastes for precise application.

Type:

  • Flux Pen: Refillable flux pens are used to apply a controlled amount of flux directly to solder points. Ideal for electronics and fine-detail work, they ensure clean joins without excess residue.
  • Polishing Paste: Used for tip maintenance and surface preparation, polishing paste extends the life of soldering tools and improves performance. It’s effective for removing oxidation and buildup.
  • Solder: This general label covers both solid and rosin-core solder types used in standard bonding jobs. Suitable for electrical wiring, pipe sealing, and repair work.
  • Solder Flux Paste: Flux paste cleans and preps metal surfaces to enhance solder flow and adhesion. Available in multiple sizes and styles, including lead-free and tinning formulations.
  • Solder Wire: Coiled wire solder in 0.25 lb. to 8 oz. sizes offers consistent feed and melt performance. Used in both residential and industrial settings, including circuit boards and metal seams.
  • Soldering Kit: All-in-one kits include essential tools and materials for basic soldering work. Designed for DIY users or light-duty shop applications.
