Material Notes:
Characteristics: Braze 600 is a copper rich eutectiferous alloy, the eutectiferous portion of which is molten at 1300EF (705EC), about 25EF before the entire composition is completely fluid. Thus to the eye, the alloy would appear to flow at 1300EF. With this type of alloy, fluidity when brazing copper based metal is decreased, but in the brazing of silver based alloys it is increased. This effect is due to the solution of the base metal. Both nickel and iron based alloys are readily wet by Braze 600 as it contains 15% zinc. Applications:Braze 600 is generally used in place of Bag-9 (Braze 650) on silverware where only one joint is required. It is also used as a second joining filler metal in step brazing on an article. It has the same flow point as BAg-9, but the color is slightly more yellow. In a properly made joint, however, the seam should be so narrow that this difference is not noticeable after polishing.
