Description: Phosphorus Tin Silicon Brazing Alloy

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.

    The higher the fluidity rating, the faster the alloy flows within the melting range. Blockade has good fluidity, yet it has the unique ability to form a cap at the joint.
