BLOCKADE phos-copper brazing filler metal features an innovative composition engineered for superior joint formation with large shoulder and cap capabilities at braze connections. This low melting temperature alloy delivers exceptional fluidity and fast-flowing properties, making it the optimal choice for tight fitting connections under two inches in diameter. Perfect for copper-to-brass applications including solenoid valves, ball valves, Schrader valves and distributors. BLOCKADE offers self-fluxing properties on copper surfaces, while its reduced melting temperature makes it an ideal solution for brass brazing applications. Fully compliant with EU Reach and RoHS directives.
Features
- Cost-effective alternative to silver bearing filler metals for reduced material costs
- Narrow melting range with superior flow characteristics enables operators to create professional "cap" or "build-up" finishes around completed joints
- Low melting point technology minimizes brass overheating risks during brazing operations
- Frequently chosen as replacement for silver brazing filler metals in demanding applications
- Silver-free composition provides significant cost savings compared to traditional brazing alloys
- Not suitable for brazing steel or ferrous alloy materials
- Phosphorus content creates low ductility intermetallic compounds with base metals
- Phosphorus-containing brazing alloys unsuitable for applications exposed to sulfur or sulfur compounds during service
- Specifically designed for copper and brass brazing with lower brazing temperatures, serving as excellent replacement for BCuP silver-bearing alloys
- Full compliance with EU Reach and RoHS environmental and safety directives
