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:
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)
