Vacuum brazing systems - Aluminium brazing under vacuum

Product catalog summary

Introduction
High-quality products made from stainless steel, ceramic, or aluminum are optimally manufactured using vacuum brazing. Ipsen provides a range of furnaces for this purpose, including manual, semi-automatic, and fully automatic single or multiple chamber systems.

Advantages of Vacuum Brazing

Adjustable furnace atmosphere for precise control.
Excellent temperature uniformity and fast control.
Environmentally friendly process without the need for flux.
No post-processing required, eliminating flux residue disposal and furnace wear.
Maintains mechanical strength and corrosion resistance of joints.
Produces high cleanliness and strong brazed joints.

Process Description
The process involves using magnesium-containing brazing alloy in batch-plated strips. During high-vacuum brazing, the aluminum oxide layer is broken and removed by vaporizing magnesium before the alloy flows.

Single Chamber Brazing Systems

Accommodates parts up to 1,600 x 7,800 x 2,400 mm.
Handles workpiece weights up to 30 tons.
Temperature uniformity better than ± 5 K.
Working vacuum less than 10^-5 mbar.

Three Chamber Brazing Systems

Throughput of up to 2,000 kg per hour.
Working vacuum less than 10^-6 mbar.
Temperature uniformity ± 5 K.
Includes a pre-chamber for thermal degreasing of parts.
