Flux

Removing of oxides and improvement of wetting characteristics

Fluxes improve wettability between base metals and braze alloy by removing surface oxides and reducing surface tension.

Depending on the base alloy, type of braze alloy and brazing temperature, different fluxes are applied.

Product	Brazing Alloy	recommended base alloys	Temp. Range [°C]
White Flux	Phosphorous containing copper + silver brazing alloys	ferrous and non-ferrous alloys, stainless steel and copper	565 – 870	RFQ
Black Flux	Phosphorous containing copper + silver brazing alloys	ferrous and non-ferrous alloys, stainless steel and carbide.	565 – 980	RFQ
GWH-LB Flux	manganese and tin containing copper brazing alloys	carbide, stainless steel, ferrous alloys	760 – 1205	RFQ
SD3 Flux	manganese and tin containing copper brazing alloys	carbide, stainless steel, ferrous alloys	537 – 1100	RFQ
L-127 Flux	manganese and tin containing copper brazing alloys	carbide, stainless steel, ferrous alloys	537 – 1100	RFQ
