Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the Alpha Fry 16 oz Acid Core Wire Solder, a dependable choice for electrical joints that demand a robust, lead-containing solution. This 16-ounce spool delivers steady supply for larger projects, with a 0.125 inch (1/8 inch) wire diameter designed to handle thicker connections and higher current tasks.

The core advantage is the integrated acid flux. The acid-core design helps the solder penetrate oxide layers and pre-tinned surfaces, promoting rapid wetting and solid bonds on copper and other metals. This makes it a practical option when you’re wiring harnesses, repairing heavy-gauge conductors, or assembling power-related components where a strong, conductive seam is essential.

  • Package size: 16 oz per package, ideal for multiple jobs without constant reordering.
  • Flux type: Acid-core flux integrated into the wire for immediate fluxing action during soldering.
  • Wire diameter: 0.125" (1/8") for thicker wires and larger joints.
  • Alloy/lead content: Lead-containing solder (not lead-free).
  • Electrical suitability: Explicitly suitable for electrical use, including heavier gauge connections where lead-based solder is appropriate.

Why this matters for your projects:

  • Ideal for automotive wiring repairs, industrial control panels, and power-supply assemblies where strong mechanical and electrical integrity is critical.
  • Accepts faster turnaround on joints by reducing prep work—the acid flux does the heavy lifting on oxidation and contaminants.
  • Consistent, predictable solder performance from a trusted brand, helping you complete builds with confidence.

Practical guidance for best results:

  • Clean surfaces after soldering to remove acid residue and protect joints from corrosion; follow appropriate post-solder cleaning steps.
  • Store the spool in a cool, dry place to maintain flux integrity and wire consistency over time.
  • Use with appropriate safety practices for lead-containing materials, including ventilation and personal protective equipment as required by local regulations.
