Blockade®

Phos-copper-tin-silicon filler metal for low temperature brazing of copper and brass.

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
