This low cost alloy is suitable for most copper-to-copper or brass joints where close tolerance can be maintained.
Harris 0 is an economical alloy designed for brazing copper to copper connections. This alloy flows quickly at brazing temperature so requires close joint tolerance, less than 0.005". is a frequent choice for copper brazing.
Harris 0 is also a suitable choice for brazing brass. In this application operators should take care to avoid over heating the brass and use Harris Stay Silv® white brazing flux.
Harris 0 is not recommended for brazing steel or other ferrous base metals. The phosphorus content will form a low ductility intermetallic with the base metal.
