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. During the vacuum heating process itself, the aluminum’s temperature is stringently kept at a single level.
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.
