AMCO 446 White is a smooth, creamy paste flux for use on most ferrous and non-ferrous metals in many combinations using any standard silver brazing alloys. Its operating range is 1050° - 1600° F. Conforms to AWS Class. FB3-A and Mil. Spec OF 499c, Type B.

AMCO 446 Black is the same base as Amco 446 White compounded with boron derivatives to extend the high-end working range to 1700° F. Conforms to AWS Class. FB3-C.

AMCO 4420 is a creamy white paste used for brazing most ferrous and non ferrous alloys using phos-copper alloys within a temperature range of 1300° - 2000° F. Conforms to AWS Class. BCuP and Mil-F 16136B, Types A & B.

PETTERSON #1 BLUE FLUX was specifically formulated for the torch brazing of steel in addition to torch welding brass, bronze and copper. It cleans and flows to form a strong bond on rusty, greasy steel and malleable iron. Additionally, Peterson #1 destroys all oxides and floats them to the surface. Conforms to AWS Class. BF3-F.

PETERSON #2 FLUX is the same as Peterson #1 but with an increased high-end temperature range. It is a bend of flux and metal which synergistically perform at temperature. Conforms to AWS Class. FB3-J
