• Designed for low temperature joining of copper and brass
• Narrow melting range
• Its flow characteristics allow operators to "cap" or "build-up" around the finished joint
• Excellent choice for brazing brass
• The low melting point reduces the likelihood of overheating on brass
• Excellent replacement for many silver bearing BCuP alloys resulting in cost savings
• Not recommended for brazing steel or other ferrous alloys
• The phosphorus content will form a low ductility intermetallic with base metal
• Due to its phosphorus content, BLOCKADE® should not be used if the braze is exposed to sulfur compounds or sulfurous atmospheres in service
• Conforms to the EU Reach & RoHS directive

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.
