Superior Flux does not manufacture any product with chemicals that are unsafe for us to work with. Consequently, none of our fluxes contain hydrazine, ferro-
Proper ventilation is a must when working with our products, with special attention necessary in closed spaces. It is always best to err on the side of caution in these crucial matters.
What is Flux
Definition of Flux
The most commonly asked question we receive from people who have never worked with fluxes is:
"What is flux?"
FLUX: A chemical composition critical to the heat joining methods of soldering, brazing, and welding that:
1. Chemically: Cleans metals surfaces to assist the flow of filler metals over base metals. Provides a protective barrier against re-
2. Thermally: Assists with heat transfer from heat source to metal surface.
3. Physically: Helps in the removal of surface metal oxides.
Definitions of Different Heat Joining Processes
SOLDERING: A process whereby similar or dissimilar metals are joined using an alloy that typically includes a base of tin combined with lead, silver, antimony, bismuth, and indium. Soldering processes cover a temperature range of 60°C -
BRAZING: A process whereby similar or dissimilar metals are joined using an alloy that typically includes a base of silver combined with nickel, copper, and zinc. High temperature brazing, generally used for carbide products, uses alloys that contain no silver but use nickel, copper, and manganese. Brazing covers a temperature range of 470°C -
WELDING: A process whereby similar metals are joined using a direct heat source to melt the base metal and a filler metal to create a uniform finished product. Most welding involves iron-
