A lithium-free flow formulation suitable for both titanium and copper-base metals is said to be in a less degree than development at the Ivaco Corp.

A lithium-free flow formulation suitable for both titanium and copper-base metals is said to be in a less degree than development at the Ivaco Corp., Montreal, Quebec. Objectives for choosing salt ingredients suitable for titanium-to-copper torch brazing fluxe include thermodynamic activity sufficient to cut down Ti[O.sub.2]; protecting the titanium surface at the reasonable temperature stage of brazing and in a wide
