HANDY FLUX HI-TEMP® - Paste
Used where brazing temperatures go into the 1600° to 2000°F (870°- 1100°C) range or for considerable lengths of time above 1450°F. This high temperature flux contains still less fluorine than type LT. It is often used with brazing alloys melting above 1600°F (870°C) - and provides the adherence and fluxing action a general purpose flux cannot give at these temperatures.
HANDY FLUX HI-TEMP® Boron modified - Paste
For high temperature Ag, Cu, Ni brazing in the range of 1600° to 2200°F (870°-1200°C), involving longer time or base metals with refractory oxides. Particularly useful where refractory oxides are formed on the metals being joined. This added capability results from the addition of a small amount of finely powdered boron to the flux.
HANDY FLUX™ - Paste

All purpose, low temperature flux for use in brazing both ferrous and non ferrous metals and alloys. HANDY FLUX™ is an active flouride/borate -type flux which begins to melt and dissolve oxides at 600°F (320°C). Fully molten at 1100°F (600°C), it provides excellent protection of parts up to 1600°F (870°C). Cleanup should be with hot water.


HANDY FLUX™ Dry
General purpose flux formulated for Hot Rodding or mixing with water for use as a paste flux. This flux was developed to stick to a heated wire or rod that is dipped into the container. Also can be mixed with water or alcohol to make a paste flux.
HANDY FLUX™ Type A-1 - Paste
For brazing aluminum bronze and other alloys containing small amounts of aluminum and/or titanium. Type A-1 will readily flux the difficult refractory oxides that form on these alloys. It is not recommended for use with aluminum or titanium base alloys. Active range 1100° to 1600°F (600° to 870°C).
HANDY FLUX™ Type B-1 - Paste

For brazing high chromium stainless steels, tungsten and chromium carbides, and molybdenum alloys. Particularly in applications where a larger amount of refractory oxides may form, use HANDY FLUX™ Type B-1 (boron modified). Its temperature range is 1100° to 1700°F (600°-925°C). It is valuable where local over-heating may occur, as in fast induction heating.


HANDY FLUX™ Type D
For automatic dispensing as controlled dabs or sprays. This flux has the same combination of salts as HANDY FLUX™, with additives to provide a lower (pourable ) viscosity . Type DB has an additional boron formulation for use with more refractory oxides, such as automated brazing of carbides.
HANDY FLUX™ Type DB
Same as above.
HANDY FLUX™ Type LT - Paste
For applications with long heating cycles, such as many furnace brazing jobs. More effective than a general purpose flux in long-heating cycle applications. Lower fluorine content results in higher melting temperature. More viscous, less active, but has a longer life. Also useful for induction heating applications, where tendency to overheat may exist. Active range: 1200° to 1600°F (650° - 870°C).
