BLOCKADE phos-copper brazing filler metal delivers innovative composition technology that enables superior large shoulder and cap formation at braze connections. This advanced low melting temperature alloy offers exceptional fluid flow properties and rapid application speed, making it the premier choice for tight fitting connections under two inches in diameter. Engineered specifically for copper-to-brass applications including solenoid valves, ball valves, Schrader valves and distributors. BLOCKADE provides self-fluxing capabilities on copper surfaces, while its reduced melting temperature delivers optimal performance for brass brazing operations. Fully compliant with EU Reach and RoHS environmental directives.
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
- Full compliance with EU Reach and RoHS environmental and safety directives
