A method of increasing oxidation resistance of a copper-silver-titanium braze on an article comprising the step of including in a copper-silver-titanium brazing material a small amount of aluminum such that the brazing material substantially comprises, in weight percent 0.5 to 3% titanium, 0.25 to 2% aluminum, 2 to 5% copper, balance silver and heating the article to a temperature sufficient to melt said brazing material.
A method of increasing oxidation resistance of a copper-silver-titanium braze on an article comprising the step of including in a copper-silver-titanium brazing material a small amount of tin such that brazing material substantially comprises, in weight percent 0.5 to 3% titanium, 0.25 to 2% tin, 2 to 6% copper, balance silver and heating the article to a temperature sufficient to melt said brazing material.
A method of increasing oxidation resistance of a copper-silver-titanium braze on an article comprising the step of including a in a copper-silver-titanium brazing material a small amount of silicon such that the brazing material substantially comprises, in weight percent 0.5 to 3% titanium, 0.25 to 2% silicon, 2 to 6% copper, balance silver and heating the article to a temperature sufficient to melt said brazing material.
