Blockade Phos-Copper Brazing Alloy

BK520R

Blockade phos-copper brazing alloy 3/32 X 20 X 25lb package

DETAILS

Blockade's innovative composition provides the ability to form a large shoulder or cap at the braze connection. It is a low melting temperature alloy which is very fluid and fast flowing. Best for tight fitting connections under two inches in diameter. Great for copper-to-brass applications such as solenoid valves, ball valves, Schrader valves and distributors. Blockade is self-fluxing on copper. Its lower melting temperature makes it an excellent choice for brass. Conforms to the EU Reach & RoHS directive.

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
