BLOCKADE flux-coated phos-copper brazing filler metal features advanced composition technology that enables superior large shoulder and cap formation at brazing connections. This high-performance low melting temperature alloy offers exceptional fluid flow properties and rapid application speeds, making it ideal for tight fitting connections under two inches in diameter. Perfectly suited for copper-to-brass brazing applications including solenoid valves, ball valves, Schrader valves and distributors. BLOCKADE provides self-fluxing capabilities on copper surfaces, while its reduced melting temperature ensures optimal performance for brass brazing operations. The pre-applied flux coating on the wire streamlines brazing processes by eliminating manual flux application requirements.
Features
- Cost-effective alternative to silver bearing filler metals for maximum material savings
- Narrow melting range with superior flow characteristics enables operators to create professional "cap" or "build-up" finishes around completed joints
- Low melting point technology significantly reduces brass overheating risks during brazing processes
- Frequently selected as high-performance replacement for silver brazing filler metals in critical applications
- Silver-free formulation provides substantial cost reductions compared to traditional brazing alloys
- Not recommended for brazing steel or other ferrous alloy materials
- Phosphorus content creates low ductility intermetallic compounds with base metal substrates
- Phosphorus-containing brazing alloys not suitable for applications with sulfur or sulfur compound exposure during service
- Specifically formulated for copper and brass brazing applications, with lower brazing temperatures serving as excellent replacement for many silver-bearing BCuP alloys
