Harris Stick 6 Silver Brazing Filler Metal 6% Silver

Product Description

The HARRIS stick 6 is a medium-range silver brazing filler metal formulated for copper-to-copper joining applications. It contains 6 percent silver and features a lower phosphorus content than the AWS BCuP-4 classification, resulting in an alloy with good ductility across a wide range of brazing situations. The melting range of the stick 6 makes it well suited for assemblies with wider joint clearance, where other alloys may not flow consistently. Plumbers, HVAC technicians, and refrigeration mechanics working with copper piping and fittings will find this filler metal a practical choice for general-service brazing tasks. It complies with the EU REACH RoHS directive.

The stick 6 is designed primarily for copper-to-copper brazing. It can also be used on copper-to-brass joints when an appropriate brazing flux is applied. The wider melting range makes it useful in field or shop situations where joint clearances are less controlled. It is not recommended for use on steel or other ferrous base metals, as the phosphorus content promotes formation of low-ductility intermetallic compounds in the base metal. It should also not be used in service environments where the brazed joint will be exposed to sulfur or sulfur compounds, as corrosion resistance may be compromised under those conditions.

Key Features

• 6 percent silver content with lower phosphorus than AWS BCuP-4 classification for improved ductility
• Medium melting range accommodates assemblies with wider joint clearance
• Suitable for copper-to-brass joints when used with appropriate brazing flux
• Corrosion resistance generally comparable to copper base metal in typical service conditions
• Complies with EU REACH RoHS directive
• Not recommended for ferrous base metals or environments with sulfur exposure

Compatibility

Designed for copper-to-copper brazing applications and compatible with copper-to-brass joints when used with an appropriate brazing flux. Not suitable for brazing steel or other ferrous base metals.

Installation Notes

Brazing with silver filler metals should be performed by a qualified plumber or HVAC-R technician following applicable codes, including IFGC and local mechanical codes where relevant. Shut off all system pressure and purge lines before beginning any brazing work on refrigerant or gas piping. Use the appropriate flux for the base metals being joined, particularly when working with copper-to-brass assemblies. Avoid using this filler in service environments where the joint may be exposed to sulfur compounds.
