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
An all-purpose, white powder flux, similar to the white paste flux but in a dry powder mixture. It is typically applied by heating the braze rod end and dipping it into the flux. The flux will adhere to the heated rod. It can be used in applications where a small amount of flux, applied during heating, provides sufficient joint protection.
Examples:
Typical Application: Use Stay-Silv White Brazing Flux on applications requiring normal heat. For use with silver brazing alloys on all metals other than aluminum, magnesium, or titanium.
