HPP 500

                GENERAL PURPOSE                                SILVER BRAZE FLUX

USES: 

Use for all silver brazing alloys.

TYPICAL DATA:  Active range is 1000 degrees to 1700 degrees F.

PROCEDURE: 

Prepare surfaces to be joined by mechanical or chemical cleaning.  Fixture parts to maintain alignment.  Joint clearance should not exceed .003".  Heat parts uniformly with a slightly carburizing flame.  Place HPP500 directly on the heated joint.  When the flux becomes clear and fluid, melt a small amount of alloy onto the joint and continue heating to uniformly spread the alloy through the entire joint area.  DO NOT OVERHEAT THE BASE METAL.  Allow the part to cool slowly, then remove flux residue with warm water.
