Description & Applications : PHOSBRAZ 738

• Alloys from the furnace brazing range are named according to their liquidus point. They are more aggressivethen their manual counterparts. Their melting range requires a rapid heating cycle to ensure that the elementsdo not separate through liquation.
• This alloy is used for strong copper brazing without need of using a flux. It is quite common to use 2 or 3different alloys on one assembly for different joints. This procedure allows for simultaneous melting of all alloygroups.
• This product is used on work shop for automatic, oven, carousel and induction brazing. Its structure alsoallows brazing in stages (reheating).

- Rods of Ø 1,5 - 2 - 2,5 - 3 mm, standard length 500 mm. Other dimensions on request. Also available inwire
