AIM Lead-Free Plumbing Solder - Silver Bearing, 0.125 in Dia, 1 Lb Spool

Premium Lead-Free Solder for Plumbing and Beyond

Produced in Canada by AIM Solder, this lead-free, silver-bearing alloy is designed to deliver smooth flow and dependable joints across brass and copper plumbing systems. When you apply it, you may notice a bright bead that wets evenly and cleanly, helping both quick repairs and larger projects feel more manageable.

The alloy blends tin, silver, copper, and antimony in precise proportions to balance melt performance and strength. The solid wire measures 3 mm (0.125 in) in diameter and is compatible with common soldering tools. The melting window of 214°C to 234°C (416°F to 454°F) provides a practical range for steady operation without overheating delicate connections.
