HYBRAZ™/® PF is an aluminium product coated with a layer of flux in an organic binder. It eliminates the need for a separate fluxing operation on a braze line, but must be used in combination with braze alloy cladding, either as a substrate to the HYBRAZ™/® PF coating or on one of the material surfaces adjoining the HYBRAZ™/® PF coated surface.
HYBRAZ™/® PB is a flux-coated aluminium product, normally an extrusion, whereby the coating compromises a reactive flux carried in an organic binder. This coating provides both the filler material and the flux during brazing, eliminating the need for clad materials or a separate fluxing operation after assembly.
The braze cycles and technologies known from the current conventional CAB (Controlled Atmosphere Brazing) process is fundamentally the same as when using HYBRAZ™/® coated products. Therefore, no major investments are needed when implementing the use of HYBRAZ™/® coated products.
Furthermore, the use of HYBRAZ™/® coated products results in:
• High degree of process control
• High quality brazed products.
The use of HYBRAZ™/® PF or PB coated products reduces the usage of flux, representing:
• No airborne flux particles in the plant
• Elimination of wet fluxing operations and
the effluents and hazardous materials it generates
• Reduced gaseous emissions
