High-temperature air braze filler materials composed of various ternary metal alloys are described. Noble metals (M) are added as a ternary constituent to a silver-copper oxide (Ag-CuO x) system. The silver (Ag) component is directly substituted with the noble metal to form a series of alloys. Addition of the noble metal increases the solidus and liquidus temperatures of the resulting air braze filler metals and increases temperatures under which seals and other sealing components formed from these filler metals can be employed.
L'invention concerne des métaux pour brasure sous air à des températures élevées composés d'alliages métalliques ternaires variés. On ajoute des métaux nobles (M) comme constituant ternaire à un système d'oxyde argent-cuivre (Ag-CuOx). Le composant argent (Ag) est directement substitué par le métal noble pour former une série d'alliages. L'adjonction du métal noble augmente les températures de solidus et de liquidus des métaux pour brasure sous air résultants ainsi que les températures dans lesquelles on peut utiliser des joints et d'autres composants d'étanchéité formés à partir des composants d'apport.
