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 for these applications Does not contain silver, so significant cost reductions are available 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 copper or brass. Lower brazing temperature, excellent replacement for many silver bearing BCuP alloys. Conforms to the EU Reach & RoHS directive Typical Applications Brass brazing
