DETAILS
BLOCKADE® is a proprietary phosphorus-tin-silicon alloy engineered as an inexpensive alternative to copper-copper and copper-brass alloys. It is self-fluxing on copper and its lower melting temperature makes it an excellent choice for brass connections. BLOCKADE® flows rapidly but can be used to "cap" brazed joints.
Features
- A low cost alternative to silver-bearing filler metals
- It has a narrow melting range, but its flow characteristics allow operators to “cap” or "build-up" around the finished joint.
- Low melting point reduces the likelihood of overheating the brass
- Often selected to replace high silver brazing filler metals
- Significant cost reductions are realized as it does not contain silver
- Not recommended for brazing steel or other ferrous alloys
- Phosphorus content will form low ductility intermetallic with base metal
- Phosphorus containing brazing alloys should not be used if the braze is exposed to sulfur or sulfur compounds in service
- For brazing copper or brass. Its lower brazing temperature makes it an excellent replacement for many silver-bearing BCuP alloys.
- Complies with the EU Reach & RoHS directive
Typical Applications
- Brass brazing
