Aluminum Brazing

“MMP has brazed prototype and pre-production components for various complex thermal systems being developed at Rocky Research. The quality of workmanship from MMP has been high, and parts have always been delivered on time, often to demanding schedule. For prototype work, the most significant value in working with MMP has been their willingness to (1) discuss design and brazing considerations for each job, (2) to suggest design changes that have improved our components as well as making them more easily brazed, and (3) to braze single items and small quantities. Rocky Research will continue to rely on MMP for prototype and production brazing and for their expertise in designing brazed assemblies.”

Vacuum Aluminum Brazing

Vacuum aluminum brazing is a vacuum furnace joining process that specifically involves aluminum and various aluminum alloys. Since it takes place in a vacuum, the brazing process occurs significantly below atmospheric pressure. When compared with other processes, this joining technique offers significant advantages: durable, flux-free aluminum joints that will not bend or break under intensive pressure. During the vacuum heating process itself, the aluminum’s temperature is stringently kept at a single level. Using slow heating and cooling cycles, this technique allows for any lingering stresses on the aluminum to be drastically reduced.

Vacuum aluminum brazing is chiefly executed by means of a furnace, meaning that different joints can be combined all at once even as the overall aluminum part reaches its necessary brazing temperature. It also means that thin and thick part cross-sections can be easily joined together.  The heat is then transferred from the furnace heating elements to the aluminum component via radiation.

Vacuum brazing is a high-end joining technology because it results in parts with extremely strong joints and with no residual corrosive flux. It is a process in which two base metals, such as aluminum plates, are joined together using a filler metal that has a melting point below that of the base metal. The filler metal, also known as a braze alloy, is drawn into the closely mated parallel surfaces of the aluminum plates by capillary action. The attributes of the vacuum brazing process include uniform heating, tight temperature control, no post cleaning processes, and process repeatability.
