Recent aluminum brazing technology and its applications. New brazing process for aluminum alloys with non-corrosive flux.

Multiphysics Simulation and Experimental Investigation of Aluminum Wettability on a Titanium Substrate for Laser Welding-Brazing Process

The control of metal wettability is a key-factor in the field of brazing or welding-brazing. The present paper deals with the numerical simulation of the whole phenomena occurring during the assembly of dissimilar alloys. The study is realized in the frame of potential applications for the aircraft industry, considering the case of the welding-brazing of aluminum Al5754 and quasi-pure titanium ...

Soldering and brazing of copper and copper alloys

Wettability of Brazing Filler Metals on Copper and Copper Alloys

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

Transport Phenomena Involved in Controlled Atmosphere Brazing of Microchannel Aluminum Heat Exchanger

Controlled atmosphere brazing (CAB) is a state-of-the-art joining technology associated with high production rates of many products, including microchannel aluminum heat exchangers. The complex designs of highly augmented compact heat transfer surfaces impose very difficult requirements for a brazing process. Regardless of the fact that brazing is a highly developed engineering art, many state-...

Aluminum and Aluminum Alloys Casting Problems

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...
