800-1300°C super high vacuum and high temperature batch system
brazing furnace for steel or copper materials
This equipment is used for AMB copper cladding process of Si3N4 and
Aln substrates.It can also be applied to vacuum and high
temperature degassing sintering of high density alloys,
tungsten-nickel alloys, tungsten-copper alloys, titanium alloys,
magnetic materials and other rare metal materials vacuum heat
treatment process.
In vacuum brazing, materials are joined by a thermal process in a
high-purity vacuum atmosphere. Vacuum brazing allow even metals
that are highly reactive to oxygen to be joined. Surfaces must be
prepared properly. Also, chemically-active alloys may be used for
brazing of dissimilar materials. Large-area brazed joints and
complicated geometries can be joined, but uniform heating and cool
down are critical for success. Typically, brazing is the last step
in assembly and no post-processing operation is required.
In this process, different precious metal, Ni, or Cu-based alloys
are used. The choice of solder depends on the base materials and
the desired properties of the joint. For example, if copper
components are to be brazed, Ag-based brazing alloys are suitable.
When joining stainless steel or high-strength superalloys, Ni-based
solders are the ideal choice. Ceramic materials such as Al203 or
Si3N4 can also be brazed without metallization of the surfaces,
though one has to use an “active” braze alloy to wet the surface of
the ceramic.

Advantages:
- No oxidation processes during brazing thanks to vacuum atmosphere
- High load-bearing capacity of joints (similar strength to base
materials)
- High corrosion resistance and high thermal stability, but is
depends on braze alloy.
- Composite of different materials is possible.
- Mating surfaces that are inaccessible from the outside may be
brazed if braze alloy is applied before assembly.
Vacuum brazing processes have a wide range of applications in a
wide variety of industries such as aerospace, energy technology,
electromobility and others. Thermal applications in these
industries often require high-purity process atmospheres.
Typical workpieces created in this way include:
Heat exchangers and cold plates (heating, cooling)
EGR cooler
Diamond and carbide tools
Turbine parts (gas turbines, aircraft turbines)
Vacuum interrupters
Electron tubes
Feedthroughs (power feeds, etc.)
Rotary anodes for X-ray apparatus
Instruments (pressure probes, thermocouples, sensors)
Machine parts (pistons, housings, burner parts)
Components in mold making (near-contour cooled molds)
