ABOUT VACUUM BRAZING
What Is
Vacuum Brazing?
A suitable filler metal melts and flows between closely fitted components in a controlled low-pressure furnace, while the base metals remain solid. This creates metallurgical joints that integrate separate parts into one assembly.
For suitable aluminum vacuum brazing projects, enclosed passages and multiple joining interfaces help translate complex cooling designs into manufacturable structures.
Controlled Heating
A defined furnace cycle coordinates temperature exposure with the selected material and filler system.
Metallurgical Joining
Prepared mating surfaces and suitable clearances support filler wetting and joint formation.
Complex Assemblies
Compatible joints can be processed together, reducing the need for separate mechanical connections.
Find out whether your assembly suits this joining process.

HOW VACUUM BRAZING WORKS
From Prepared Parts
to a Brazed Assembly
Geometry, surface preparation and the furnace cycle work together to form the joint. Reviewing each stage helps protect internal passages and joining interfaces.
01
Surface Preparation
Prepare clean mating surfaces so contaminants do not interfere with the planned joining conditions.
02
Assembly & Filler Placement
Position compatible filler and components with suitable joint clearances and fixtures.
03
Vacuum Environment
Evacuate the chamber to the processing conditions specified for the selected material system.
04
Controlled Heating & Brazing
Follow a defined thermal cycle so molten filler can wet suitable surfaces and flow into the joints.
05
Controlled Cooling
Cool the assembly under appropriate conditions before removal and inspection.
Temperature, vacuum conditions and heating and cooling profiles depend on the base materials, filler system, assembly geometry and qualified process. Parameters are confirmed for each project.
Coordinate the joint design and process before manufacturing begins.
Review Your Brazing ProcessMATERIALS & FILLER SELECTION
Material Compatibility
Comes First
Aluminum vacuum brazing depends on the exact alloy, filler system and joint design. Reviewing these together helps avoid committing an unsuitable material combination to production.
Aluminum Alloys
Conductivity, weight and machinability make aluminum useful for thermal components. Confirming alloy and temper helps establish whether the proposed joining route is suitable.
Brazing Filler Materials
Melting range, wetting behavior and joint clearance guide filler selection. A compatible system supports the intended bond without relying on an assumed universal alloy.
Material & Joint Evaluation
Oxide behavior, thermal expansion and service conditions influence feasibility. Reviewing the complete assembly helps align aluminum brazing services with operating requirements.
Share exact material grades, temper, drawings and service conditions. Other material combinations require a separate compatibility review.

Vacuum Brazing FAQs
Clarify material suitability, joining choices and inspection requirements before preparing your manufacturing inquiry.
What is vacuum brazing used for?
Vacuum brazing joins compatible metal parts in a controlled low-pressure furnace. It can integrate enclosed passages and multiple interfaces into thermal assemblies, helping manufacture structures that would be difficult to join mechanically.
Can you provide aluminum vacuum brazing services?
JBT can review aluminum vacuum brazing requirements alongside machining, assembly preparation and inspection. Send the exact alloy, temper, drawings and quantity so the processing scope can be evaluated and confirmed.
Is vacuum brazing suitable for liquid cold plates?
It can be suitable for compatible cold plate assemblies with properly designed joining interfaces. Material compatibility, passage geometry and leak and pressure verification should be reviewed together before choosing the route.
Can all aluminum alloys be vacuum brazed?
No. Alloy chemistry, temper, surface condition, filler selection and thermal exposure influence suitability. A material review helps identify whether the proposed combination is appropriate or an alternative joining route is needed.
Can vacuum brazing create leak-tight joints?
A suitable design and controlled process can produce a fluid-containing joint, but leak-tight performance must be verified. Agree the test method, medium, pressure, duration and allowable leakage before production.
What is the difference between vacuum brazing and friction stir welding?
Vacuum brazing uses molten filler to join compatible surfaces while the base metals remain solid. Friction stir welding joins material through a rotating tool in a solid-state process. Geometry, material and tool access guide the choice.
Do brazed assemblies need additional machining or testing?
They may need finishing of critical surfaces, dimensional inspection and specified leak or pressure checks. Planning these operations early helps account for dimensional changes and establishes clear acceptance criteria.
What information is required for a vacuum brazing quotation?
Provide 2D drawings or 3D CAD, material grades, quantity, assembly details, operating conditions and inspection requirements. These inputs help define the manufacturing scope and support a more useful quotation.
