Careful production control of the eutectic melting point composition results in the FL-7 melting at a consistently lower temperature.
Cladding Alloys Aluminium Brazing
Sep 29, 2010 This alloy is used in flame brazing and in induction brazing. For furnace brazing (i.e. controlled atmosphere brazing with non-corrosive flux), the filler alloys of clad aluminium sheet is either AlSi7 (AA 4343) or AlSi10 (AA 4045). Filler alloy selection will depend on the specific application and the design of the parts to be joined.Compatibility of R134a and PAG Oil - Aluminium Brazing It can be used for all aluminum brazing applica-tions (e. g., controlled atmosphere or furnace brazing [CAB], flame brazing, and -induction brazing). The cesium-containing flux allows to braze aluminum alloys with a slightly higher magnesium content (i.e. up to 0.6 0.8%).Controlled Atmosphere Aluminium Brazing (CAAB) Furnace Controlled Atmosphere Aluminum Brazing (CAAB) Furnace Overview AFC-Holcroft designed (Controlled Atmosphere Aluminum Brazing) CAAB provides the most advanced and state-of-the-art technological edge for processing aluminum heat exchangers such as radiators, heater cores, condensers, evaporators, charge air and oil coolers.

Controlled atmosphere brazing of aluminum - ScienceDirect
Jan 01, 2013 Materials involved in controlled atmosphere brazing (CAB) of aluminum. Light weight and high thermal conductivity are two of the properties that make Al alloys ideal materials for heat transfer devices. Additionally, aluminum has the advantages of good formability, fairly good corrosion resistance and being relatively cheap.Cited by: 15Controlled atmosphere brazing of aluminum heat exchangers Controlled atmosphere brazing technol-ogy provides a cost-effective and environmentally friendly manufacturing method for these advanced heat transfer devices. Novel heat exchanger design and continuous development of new materials, as well as stringent requirements in terms of device reliability, impose new challenges on the manufacturing process.Cited by: 2EAA Aluminium Automotive Manual Joining 6.

Check CAB- Control.The Effects of Residual Controlled Atmospheric Brazing Automobile and truck heat exchangers, including radiators, heater cores, oil coolers, charge air coolers, etc., are predominantly manufactured with aluminum alloys using a process known as controlled atmosphere brazing (CAB). In the CAB process, a fluxing agent (such as potassium fluoroaluminate), is applied to the surfaces to be joined.Transport Phenomena Involved in Controlled Atmosphere present on all aluminum surfaces must be destroyed to allow the free flow of molten clad during brazing. For a controlled atmosphere Al brazing process (CAB process), this task is accomplished by a deposition of flux on aluminum surface to be joined (Swidersky, 2001). A tightly controlled inert gas (N 2) atmosphere prevents the
