Welders Choice 59802199 Silicon Bronze Brazing Rod

Product Description

The WELDERS CHOICE 59802199 is a silicon bronze brazing alloy rod used for gas or torch brazing of copper, brass, and bronze base metals. Meeting industry specification ERCuSi-A, this rod measures 1/16 inch in diameter and 36 inches in length, with a net weight of 1 pound. It is well suited for HVAC, plumbing, and refrigeration work where a strong, corrosion-resistant filler metal is required. Licensed plumbers, HVAC technicians, and welding professionals reach for silicon bronze rod when joining dissimilar metals or making repairs on copper-alloy components where a lower-melting filler is preferred over silver alloy.

This brazing rod is used in both residential and light commercial applications. Typical scenarios include joining copper tubing, repairing brass fittings, and fabricating or restoring bronze components. The ERCuSi-A classification makes it a recognized choice for torch brazing setups used in plumbing rough-in, HVAC refrigerant line work, and general metal fabrication shops. It works with oxy-acetylene and oxy-fuel torches and is packaged as a single rod for flexible job-site use.

Key Features

• ERCuSi-A industry specification for consistent filler metal composition
• Silicon bronze alloy provides good corrosion resistance on copper and brass joints
• 1/16 inch diameter rod fits standard torch brazing technique for thin-to-medium wall copper
• 36-inch length gives adequate working length per rod with minimal waste
• 1-pound net weight per unit for straightforward job-site inventory tracking

Compatibility

Designed for torch brazing of copper, brass, and bronze base metals in plumbing, HVAC, and general metal fabrication applications where an ERCuSi-A silicon bronze filler alloy is specified.

Installation Notes

This brazing rod is applied by licensed plumbers or HVAC technicians using oxy-fuel or oxy-acetylene torch equipment. Ensure all system pressure is relieved and the work area is properly ventilated before beginning any brazing operation. Follow applicable local plumbing and mechanical codes, including IFGC and IPC requirements where brazing of gas or refrigerant lines is involved. Allow brazed joints to cool fully before pressure-testing or disturbing the assembly.
