Product Description

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. – See more at: http://www.harrisproductsgroup.com/en/Products/Alloys/Brazing/Phos-Copper/Blockade.aspx#sthash.UO5cL0vO.dpuf
