Why Switch to Brazing in a Vacuum Furnace

Vacuum brazing is particularly suitable for connecting geometrically complex and precise components, mostly composed of materials such as aluminum or titanium, and the brazing process does not produce pollution. It is also sometimes preferred over a hydrogen atmosphere when brazing very large parts due to its ability to purge occluded, tight-fitting areas.

For one thing, vacuum furnace brazing deoxidizes the metals being joined. On the other hand, and more importantly, it can eliminate undesirable reactions in hydrogen or other inert gases. When the heating system reaches the melting temperature of the brazing alloy (such as solder or die-cut preform), the extremely low pressure environment or vacuum environment will promote wetting of the joint surface, causing the solder to flow into the joint through capillary action.

Finally, the method can also be used to metallize ceramic surfaces, joining ceramics to other metals via vacuum active metal brazing.

Key advantages and benefits

Our vacuum brazing operations provide a clean process that removes harmful oxides and prevents adverse reactions, resulting in high-quality brazed joints. For these reasons, vacuum brazing is highly sought after by the semiconductor, medical, and aerospace industries as it guarantees precise tolerances, is a clean manufacturing process, and gives ample time and cost savings. The parts it produces have bright, clean and beautiful surfaces and do not require any post-weld treatment, whereas common welded parts usually require machining. Additionally, compared to welding processes, there are almost no wall thickness restrictions when brazing parts or components with complex geometries.

Applications of vacuum brazing

The most common applications utilize the heat flow capabilities of aluminum and the deoxidizing properties of the process to join specialty parts such as heated and cooled assemblies, microchannel heat exchangers, aircraft components, sensors, medical equipment, structural components and other heat-related products The product. We focus on the joining of active materials in the vacuum brazing process, or those materials in the brazing process that require preferential removal of oxides.

Vacuum brazing aluminum is an important part of our business, if anyone would like to know more about our brazing methods, especially methods of brazing aluminum to itself or other metals such as Copper, Stainless Steel and For the brazing of other refractory metals and aluminum, in order to avoid the generation of brittle intermetallic phases, we provide specific design guidelines for obtaining excellent brazing joints.
