Feature
- Can be bonded between dissimilar metals as well as homogeneous
- Reduce costs and enable design of various parts : It is easy to join products of different sizes and thickness to reduce cost and design various parts.
- Strong joint strength : Stainless steel can be designed with tensile strength over 130,000 PSI
- Ability to create beautiful and exquisite joints
- Maintaining various properties such as cleaning, confidentiality, internal corrosion, etc :
Because the joints are metallurgical, they can be made to have various properties such as ductility, shock resistance,
vibration tolerance, confidentiality, thermal conductivity, and corrosion resistance
- Mass production is possible through automation
Furnace brazing operation
Furnace brazing features
- The whole product is heated up in Furnace.
- Precise temperature control is relatively easy and uniform quality can be achieved.
- Be suitable for mass production.
- Can get a clean product because the product does not oxidize during brazing.
- For sealed products, it is recommended to remove the Flux.
- High strength and good brazing point can be obtained.
- Brazing complex products is easy.
Specification and Features of Vacuum Furnace
United States
Aber lpsen
vacuum furnace
- No oxide is produced because brazing is done in a vacuum
- High quality levels can be achieved by brazing by evaporating 100 percent of the oil content (look clean)
- Charge size: W610×H610×D1,016mm
- Loadings: 680kg (at 1,316°C)
Features
- Rapture, can be brazed without oxidation
- Highly confidential brazing possible
- Quality Improvement of Connections by Degas
- Brazing of non-ferrous metals such as titanium and their alloys is possible
- High quality heat treatment is possible
