Welders Choice 59802231 Silicon Bronze Brazing Rod

Product Description

The WELDERS CHOICE 59802231 is a silicon bronze brazing alloy rod designed for gas and torch brazing applications in plumbing, HVAC, and general metal fabrication work. Manufactured to the ERCuSi-A industry specification, this rod measures 1/8 inch in diameter and 36 inches in length, making it compatible with standard brazing setups. The silicon bronze alloy delivers good flow characteristics and corrosion resistance, making it a reliable choice for joining copper, brass, and bronze base metals. Each package contains one rod and ships at approximately 1.09 pounds. Licensed trade professionals and experienced fabricators typically use this alloy for repair and new-construction brazing tasks.

This brazing rod is suited for residential and light commercial applications where a copper-based filler metal is required. Common uses include sweat and torch brazing of copper tubing assemblies, HVAC line set repairs, plumbing fixture connections, and general sheet metal or fabrication work involving copper-alloy base metals. The ERCuSi-A specification means it meets recognized industry standards for silicon bronze filler metals, ensuring consistent deposit chemistry across production and repair work. Plumbers, HVAC technicians, and pipefitters working with copper and bronze components will find this rod appropriate for typical torch brazing procedures.

Key Features

• ERCuSi-A industry specification for consistent silicon bronze chemistry
• 1/8 inch diameter rod suited for standard torch brazing torches and tips
• 36 inch rod length provides good yield per stick for typical joint work
• Silicon bronze alloy provides corrosion resistance on copper and brass joints
• Single-rod packaging allows purchase in exact quantities needed

Compatibility

Designed as an ERCuSi-A silicon bronze filler rod for torch brazing of copper, brass, and bronze base metals in plumbing and HVAC applications.

Installation Notes

Brazing with silicon bronze rod is typically performed by licensed plumbers, HVAC technicians, or qualified pipefitters following applicable local codes, including IFGC and IPC guidelines where relevant. Always purge or depressurize the system and ensure the work area is properly ventilated before applying heat. Use appropriate personal protective equipment including eye protection and heat-resistant gloves when torch brazing. Do not apply flux or shielding gas beyond what the ERCuSi-A specification and joint design require without verifying compatibility with the base metal.
