METHOD OF BRAZING ALUMINUM TO STAINLESS
Aluminum alloy has a series of properties such as high specific strength, high specific stiffness, light weight, and corrosion resistance. Its application fields are constantly expanding, especially in automobile manufacturing and other industries. It has broad application prospects. However, com...
Vacuum sintering process curve
The vacuum sintering process curve has a direct impact on the sintering quality. In order to ensure a good sintering effect, an appropriate preheating temperature should be selected and sufficient preheating should be carried out. At the same time, an appropriate sintering temperature and time sh...
Research on vacuum sintering process of low temperature solder
Commonly used chip mounting technologies mainly include solder sintering and conductive adhesive bonding. The conductive adhesive bonding process has the advantages of simple operation and low cost, but its thermal conductivity is poor. For chips with high power and need to dissipate heat, the so...
Metallurgical Studies of the Vacuum Brazing of Aluminum
1.Brazing materials When vacuum brazing aluminum and aluminum alloys, most aluminum-based solder materials used for vacuum brazing are based on aluminum-silicon eutectic and add a small amount of magnesium, an element that can improve wetting properties. Because magnesium is a very strong activat...
Problems encountered in vacuum brazing of stainless steel
The Cr2O3 oxide film formed on the surface of stainless steel is quite stable and difficult to remove. To realize vacuum brazing of stainless steel, it is necessary to understand the removal mechanism of Cr2O3 oxide film in vacuum during the brazing process. Stainless steel vacuum film removal me...
Vacuum Brazing and its Applications
For ceramic materials, everyone’s first impression is definitely its high melting point, high insulation performance and poor thermal stability. In the process of welding assemblies using ceramics and metals as connecting materials, these characteristics often add great difficulty to tradit...
Why does vacuum heat treatment always use nitrogen?
Vacuum heat treatment usually requires the use of nitrogen as the treatment atmosphere, mainly for the following reasons: Prevent oxidation: Nitrogen can form a protective oxide layer at high temperatures to protect metal products during heat treatment from chemical reactions such as oxidation an...
Vacuum brazing of refractory metals
When are refractory metals combined with vacuum brazing? Due to the oxidation or inherent contamination of active metals, vacuum brazing is often used when connecting refractory metals to active metals, such as titanium and aluminum. Refractory metals refer to metals with very high melting tempe...
Why Switch to Brazing in a Vacuum Furnace
Vacuum brazing is particularly suitable for connecting geometrically complex and precise components, mostly composed of materials such as aluminum or titanium, and the brazing process does not produce pollution. It is also sometimes preferred over a hydrogen atmosphere when brazing very large par...
Vacuum Furnaces: Everything You Need To Know
Vacuum furnaces have short cycle times. Heating 1,000 pounds of charge in a heating chamber that is already at 1,000°C takes 60 minutes, whereas heating the same chamber with 1,000 pounds of charge from cold would take 90 minutes (1.5 times longer). Advantages in cycle times and energy usage resu...
