Eco GreenFlux FP 38917D Flux

Eco GreenFlux FP 38917D

The Eco GreenFlux FP 38917D flux is boric acid-free and consists of more than 80% complex fluoborates. It is specially designed for brazing tungsten carbides on steels and stainless steels with manganese and nickel-containing brazing alloys.
This flux can be used in automatic processes with pressure dispensers.

Applications
Eco GreenFlux FP 38917D is used with silver alloys containing manganese and nickel, such as: Castolin 1703, 8270, 1701, 1704, EcoBraz 38249, 38298.
Eco GreenFlux FP 38917D is recommended for bonding hard metals such as tungsten carbide with steel or stainless steel as well as copper and its alloys.

Processing instructions
Preparation

• If necessary, clean the joint surfaces and round off any sharp edges.
• If necessary, degrease the parts with a suitable solvent.
• Coat the surfaces of the parts to be joined with a brush. The flux reduces surface oxides, promotes the capillary effect of the filler metal and serves as a temperature indicator.
• Place the parts in their final position. Set the torch so that you obtain a neutral or "slightly carburizing flame". Heat the parts to be joined evenly to the joining temperature.
• Place the solder on the joint, melt a drop and spread it with a continuous movement of the flame. The alloy is distributed over the hottest areas of the surfaces to be joined.
• Melt the filler metal until the joint is completely filled.

Cleaning

• The residues of Eco GreenFlux FP 38917D are water-soluble. They are usually removed by washing with hot water or by wiping with a damp sponge.
• Mechanical cleaning can also be carried out.
