All Superior Carbide Brazing Fluxes are RoHS compliant.
Superior No. 601B/3411 is a general-purpose black brazing flux for BAg Alloy applications, particularly BAg-24 filler alloy used for saw-blades, and conforms to AMS 3411 specification.
Superior No. 609LB is a low-boron (LB) modified brazing flux for hi-temp carbide applications. It is used in tandem with Manganese-containing, low fuming bronze and Nickel-Silver. No. 609LB is particularly effective for larger carbide parts as the addition of boron enables the flux to last longer during brazing. This flux conforms to AMS 3417 specification.
Superior No. 612 is formulated as a general purpose carbide brazing flux. It is used in tandem with Manganese-containing, low fuming bronze and Nickel-Silver. No. 612 is typically used for brazing smaller carbide parts, such as mining drill bits and conforms to AMS 3417 specification.
All Superior carbide brazing fluxes ship as non-hazardous.
