BLOCKADE phos-copper brazing filler metal features advanced composition technology engineered to create superior large shoulder and cap formation at brazing connections. This high-performance low melting temperature alloy delivers exceptional fluid flow characteristics and rapid processing speeds, optimized for tight fitting connections under two inches in diameter. Specifically designed for copper-to-brass brazing applications including solenoid valves, ball valves, Schrader valves and distributors. BLOCKADE offers self-fluxing properties on copper materials, while its reduced melting temperature provides outstanding performance for brass brazing operations. Meets all EU Reach and RoHS compliance requirements.
Features
- Economical alternative to silver bearing filler metals delivering significant cost savings
- Narrow melting range combined with superior flow characteristics allows operators to create professional "cap" or "build-up" finishes around completed joints
- Low melting point technology minimizes brass overheating risks during brazing operations
- Preferred replacement choice for silver brazing filler metals in demanding applications
- Silver-free composition offers substantial cost reductions versus traditional brazing alloys
- Not suitable for brazing steel or other ferrous alloy materials
- Phosphorus content forms low ductility intermetallic compounds with base metal materials
- Phosphorus-containing brazing alloys unsuitable for applications exposed to sulfur or sulfur compounds during service conditions
- Optimized for copper and brass brazing with lower brazing temperatures, serving as effective replacement for many silver-bearing BCuP alloys
- Full compliance with EU Reach and RoHS environmental and safety regulations
