Materials
SP3259-022 Rev 01 (W196655MX), 0.5”(12.7mm) tube OD, 0.6”(15.24mm) fitting OD, 3.5”(88.9mm) overall length assembled, copper filler ring, banjo fitting
Power: 9.23kW maximum
Temperature: Over 1600°F (871°C)
Time: 10 to 15 seconds to temperature for braze cycle
Recommendations:
An IR system and temperature controller are highly recommended for this application. It will keep the part from overheating and hold it at temperature which will allow the alloy to flow correctly around the braze joint and improve the braze quality and time cycles. A nitrogen or argon atmosphere is recommended to prevent oxidation.
