    Abstract

    An induction brazing process using a silver filler material was developed for the copper alloy GlidCop Al-15. Hardness measurements indicated recrystallization did not occur during brazing. Failure of overlap joints in tensile occurred outside the joint when the overlap to base metal thickness ratio was greater than 1.5. The average unit tensile strength of overlap joints increased with this ratio and became constant at a ratio of 5. The average unit shear strength continued to decrease with an increasing ratio. Fatigue results of unbrazed GlidCop Al-15 were described by a total strain-life curve for both high cycle and low cycle fatigue. Brazed joints were tested only in the elastic strain region. Fatigue strengths of induction and furnace brazed butt joints were about the same but less than that of the cold worked GlidCop Al-15 alloy.
